What this book claims, and who wrote it.

  • — The book's one-line promise
  • — The author and where the book stands

A comprehensive guide for transforming reactive, wasteful maintenance departments into proactive, strategic, and profit-generating business functions by implementing a structured framework of best practices and benchmarking.

The need-to-know

A significant portion of all maintenance expenditures, estimated at one-third, is wasted due to reactive approaches and systemic inefficiencies. Effective maintenance management is a system of interconnected practices; a robust work order system is the foundation for effective planning, which in turn enables preventive maintenance and optimized inventory control. The transition from a reactive to a proactive maintenance organization requires a disciplined, sequential approach, mastering basics like work orders and planning before advancing to more sophisticated techniques.

About this guide

The guide describes these challenges, steps and possible outcomes.

Who it is for

A maintenance manager, plant manager, or operations executive responsible for the performance and cost-effectiveness of their organization's physical assets.

Challenges

  • In practice · The maintenance department is stuck in a reactive 'fire-fighting' cycle, leading to excessive equipment downtime, high overtime costs, wasted labor, uncontrolled inventory expenses, and low productivity.
  • For the reader · They feel frustrated, overwhelmed, and undervalued, constantly battling crises, struggling to justify their budget, and unable to implement the long-term improvements they know are needed to prove their department's value.

Steps to consider

  1. 1Analyze your current maintenance effectiveness using the detailed self-assessment survey.
  2. 2Adopt the principles of benchmarking to learn from best-in-class organizations.
  3. 3Implement foundational best practices in a systematic order: a robust work order system, maintenance planning and scheduling, an effective preventive maintenance program, and controlled inventory.
  4. 4Advance to higher-level practices like predictive maintenance and reliability engineering.
  5. 5Use a comprehensive reporting and analysis system to measure performance and drive continuous improvement.

Risks

The department remains stuck in a costly, reactive fire-fighting mode, draining company profits. Unexpected equipment failures continue to disrupt production, hurt quality, and damage customer relationships.

Intended result

The maintenance organization becomes proactive, with over 80% of work planned and scheduled. Equipment availability and reliability increase dramatically, boosting production capacity and product quality.

Set the record straight

What this book sets straight

The common beliefs this book pushes back on.

The myth

Maintenance is a necessary evil, a cost center that just fixes things when they break.

The reality

Maintenance is a core business process and a profit center that, when managed proactively with best practices, can significantly increase production capacity, reduce operational costs, enhance product quality, and provide a strategic market advantage.

The myth

The best way to improve maintenance performance is to cut the maintenance budget.

The reality

True improvement requires a strategic investment in systems, training, and processes like planning and preventive maintenance. This may initially increase costs but ultimately leads to massive long-term savings by eliminating waste, downtime, and lost production.

The constructs

Disciplined Work Order System

The extent to which the organization systematically uses a formal work order system to initiate, track, record, and analyze all maintenance activities, covering 100% of man-hours, materials, and jobs performed.

Maintenance Planning and Scheduling

The practice of using dedicated planners to prepare for maintenance work in advance by defining the scope, materials, tools, and labor required, and then coordinating with operations to schedule the work on a weekly basis.

Preventive Maintenance (PM) Program

A system of planned maintenance activities, including inspections, lubrication, and adjustments, designed to improve equipment life and avoid unplanned failures. Its effectiveness is measured by its coverage of critical equipment and its on-time completion rate.

Maintenance Inventory and Purchasing Control

The set of practices for managing maintenance materials and spare parts to ensure high availability (service level) while minimizing inventory holding costs, supported by accurate records and maintenance control over stocking decisions.

Maintenance Training

The formal and ongoing process of developing the technical and interpersonal skills of maintenance personnel, including craft technicians, planners, and supervisors, to ensure they can effectively maintain increasingly complex equipment.

Operations Involvement

The degree to which the operations or production department takes ownership of their equipment by performing basic maintenance tasks like inspections and lubrication, and actively participating in the work order and scheduling process.

Management Support and Attitude

The degree to which senior and plant management view maintenance as a critical, value-adding business function rather than a necessary evil, demonstrated through visible support, adequate resource allocation, and a focus on long-term asset health over short-term production targets.

Proactive Maintenance Orientation

The organizational state where the majority of maintenance work is identified and prepared in advance (planned, scheduled, preventive) rather than in response to unexpected equipment failures (reactive, emergency).

Maintenance Labor Productivity ('Wrench Time')

The percentage of a maintenance technician's paid time that is spent performing direct, hands-on work, as opposed to waiting for parts, instructions, or traveling.

Maintenance Materials Availability

The degree to which the correct spare parts and materials are available in the storeroom when needed for maintenance work, preventing delays and improving the efficiency of repairs.

Asset Availability and Reliability

The extent to which equipment and facilities are operational and capable of performing their intended function when required, measured by uptime, mean time between failures (MTBF), and overall equipment effectiveness (OEE).

Maintenance Cost-Effectivenessthe outcome

The efficiency of the maintenance function, measured by the total maintenance cost (labor, materials, contractors) relative to the value of the assets being maintained, reflecting the reduction of waste and optimization of resources.

Overall Profitability

The ultimate financial performance of the company, enhanced by the maintenance function through increased capacity (from higher asset availability) and decreased expenses (from greater cost-effectiveness).

Operations Involvement
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section explains how production staff take ownership of equipment by doing basic care and joining the scheduling process. It sets out what to hand over and how to keep it going.

Operations Involvement

The degree to which the operations or production department takes ownership of their equipment by performing basic maintenance tasks like inspections and lubrication, and actively participating in the work order and scheduling process.

Why it matters. When operations treat equipment as maintenance's problem, early warning signs go unseen and maintenance cannot get the equipment access it needs to schedule work.

Myth

Asking operators to do inspections and lubrication takes them away from production and is a union or productivity problem.

Reality

Operators are the first to notice changes in sound, heat, and leaks, so basic care catches degradation hours or days before the maintenance crew would. The trade-off is small compared to the downtime avoided, provided the tasks are simple and well-defined.

Tools for this
The least you need to know
  • Operator-performed basic care is an early-warning system, not a favor to maintenance.
  • Operations' commitment to equipment release is what makes weekly schedules stick.
  • Hand over simple, trained, time-protected tasks rather than vague responsibilities.

Management Support and Attitude
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section examines how management behavior shapes whether maintenance improvements take hold. It shows what visible support looks like in resources and decisions.

Management Support and Attitude

The degree to which senior and plant management view maintenance as a critical, value-adding business function rather than a necessary evil, demonstrated through visible support, adequate resource allocation, and a focus on long-term asset health over short-term production targets.

Why it matters. Without management backing, practices like planning and PM are abandoned the first time a production target is at risk.

Myth

Management support means approving the maintenance budget and sponsoring the improvement project.

Reality

Support is shown in what managers do when a production target conflicts with a scheduled PM or planned outage. Words and initial funding are cheap; protecting planned work under pressure is what changes behavior and amplifies every other practice.

Tools for this
The least you need to know
  • Management attitude is judged by decisions under conflict, not by statements.
  • It acts as an amplifier: strong support makes proactive practices stick, weak support undermines them.
  • Standing resources and KPI reviews signal that maintenance is a value-adding function.

Proactive Maintenance Orientation
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section defines the shift from firefighting to prepared work and how to measure it. It shows how planning and PM combine to move your work mix.

Proactive Maintenance Orientation

The organizational state where the majority of maintenance work is identified and prepared in advance (planned, scheduled, preventive) rather than in response to unexpected equipment failures (reactive, emergency).

Why it matters. Your reactive-to-planned ratio is the best single indicator of whether availability and cost gains are coming or whether you are in a permanent crisis loop.

Myth

A proactive orientation is a mindset that can be adopted through a cultural push or slogan.

Reality

It is an outcome of structural practices: planning, scheduling, and PM generate the planned work that displaces emergencies. Without them, the mindset collapses the first time something breaks.

Tools for this
The least you need to know
  • The planned-versus-reactive work mix is the core measure of this construct.
  • It results from planning and PM practice, not from attitude alone.
  • Each emergency should trigger a root-cause question about the missing preventive step.

Maintenance Labor Productivity ('Wrench Time')

  • Benchmarking Best Practices in Maintenance Management
In this section

This section explains wrench time, how to measure it, and what really drives it. It identifies the delays that take technicians off the tools.

Maintenance Labor Productivity ('Wrench Time')

The percentage of a maintenance technician's paid time that is spent performing direct, hands-on work, as opposed to waiting for parts, instructions, or traveling.

Why it matters. Typical wrench time is well below half of paid hours, so each ten-point gain releases capacity equal to hiring more technicians without adding cost.

Myth

Low wrench time means technicians are not working hard enough.

Reality

Most lost time is caused by the system: waiting for parts, permits, instructions, or equipment access, and traveling for tools. The fix lies in planning, materials, and training, not in pressure on individuals.

Tools for this
The least you need to know
  • Wrench time is a systems measure; improve it through planning, parts, and skills.
  • Work sampling reveals the real delay breakdown that self-reports miss.
  • Raising wrench time frees capacity equivalent to additional headcount.

Maintenance Materials Availability
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section covers how to measure and improve whether the right parts are there when a job starts. It connects storeroom performance to delays on the job.

Maintenance Materials Availability

The degree to which the correct spare parts and materials are available in the storeroom when needed for maintenance work, preventing delays and improving the efficiency of repairs.

Why it matters. Every stockout on a scheduled job turns planned work into waiting, shifting technicians to something else and pushing the work back into the reactive queue.

Myth

Materials availability is just a storeroom service-level number that stores staff can manage on their own.

Reality

A good stock level on paper can still miss the parts for planned jobs, because availability depends on planners specifying parts early and kitting them. It is a shared outcome between planning, purchasing, and stores.

Tools for this
The least you need to know
  • Availability should be measured at the job level, as jobs delayed by parts.
  • Kitting parts for scheduled work links planning to the storeroom.
  • Inventory control sets the potential, but planning determines whether parts reach the job.

Asset Availability and Reliability
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section covers how to measure uptime, MTBF, and OEE in a way that supports real benchmarking. It shows how to read them as outcomes of your maintenance practice.

Asset Availability and Reliability

The extent to which equipment and facilities are operational and capable of performing their intended function when required, measured by uptime, mean time between failures (MTBF), and overall equipment effectiveness (OEE).

Why it matters. These are the results production and finance care about, and they feed profitability directly, so measuring them badly means misjudging both performance and where to invest.

Myth

High availability proves that your maintenance practices are strong.

Reality

Availability can be held up by heroic repairs, redundant equipment, or excess spares while the underlying reliability is poor. MTBF and the planned-work share show whether availability is sustainable or purchased with overtime.

Tools for this
The least you need to know
  • Pair uptime with MTBF so that quick recovery does not mask poor reliability.
  • Consistent definitions determine whether a benchmark means anything.
  • Availability is the lagging result of proactive work, so look to the work mix for early signals.

Maintenance Cost-Effectiveness
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section shows how to judge maintenance spending relative to asset value and to results. It explains how to avoid reading low cost as good performance.

Maintenance Cost-Effectiveness

The efficiency of the maintenance function, measured by the total maintenance cost (labor, materials, contractors) relative to the value of the assets being maintained, reflecting the reduction of waste and optimization of resources.

Why it matters. Cutting maintenance spend looks like savings until failures raise costs later, so judging cost wrongly leads to decisions that lower profit.

Myth

The lowest maintenance cost as a percent of asset value signals the best-run maintenance operation.

Reality

Very low spend often reflects deferred work that returns as breakdown costs, and high spend may reflect poor productivity or reactive work. Cost-effectiveness has to be read alongside availability and the planned-work share.

Tools for this
The least you need to know
  • Cost is judged relative to asset value and always alongside availability.
  • Unusually low spending often signals deferral that will reappear as failure costs.
  • Raising wrench time and the planned-work share are the main routes to lasting cost reduction.

Overall Profitability
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section shows how maintenance performance becomes a financial result, so you can tie benchmark gaps to margin rather than to departmental scorecards. It covers the two routes by which maintenance moves profit: more productive capacity and lower cost.

Overall Profitability

The ultimate financial performance of the company, enhanced by the maintenance function through increased capacity (from higher asset availability) and decreased expenses (from greater cost-effectiveness).

Why it matters. If you cannot trace a maintenance benchmark to profit, you will either fund cuts that quietly erode capacity or fund reliability work that never earns its keep.

Myth

Maintenance is a cost center, so the way to improve its contribution to profit is to benchmark its spend against peers and push it down.

Reality

Maintenance moves profit through two levers, and the capacity lever often outweighs the expense lever: an hour of recovered uptime on a constrained asset can be worth more than the entire cost of the work that saved it. Cutting spend without watching availability can reduce profit even as the maintenance budget looks better against peers.

Tools for this
The least you need to know
  • Maintenance affects profit by adding sellable capacity and by removing unnecessary cost; measure both, never just one.
  • Value downtime on bottleneck assets at lost contribution margin, which usually dwarfs the direct cost of repair.
  • A maintenance benchmark is only decision-ready once you can state its effect in financial terms.

Disciplined Work Order System
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section shows what separates a work order system that merely exists from one that captures every hour, part, and job. You get the steps to turn it into the data backbone that planning and benchmarking depend on.

Disciplined Work Order System

The extent to which the organization systematically uses a formal work order system to initiate, track, record, and analyze all maintenance activities, covering 100% of man-hours, materials, and jobs performed.

Why it matters. If the system captures only part of the work, every downstream metric, from backlog to cost per asset, is built on fiction and your benchmark comparisons mislead you.

Myth

Having a CMMS with work orders for major jobs means you already run a work order system.

Reality

The value comes from coverage and closure, not from owning software. Work that skips the system, such as hallway requests, quick fixes, and unrecorded overtime, makes history unreliable and leaves planners with nothing to plan from.

Tools for this
The least you need to know
  • A work order system is only as credible as the share of payroll hours it accounts for; reconcile it to payroll.
  • Emergency work belongs in the system too, entered after the fact if necessary.
  • Coded closeout data turns routine paperwork into the evidence for planning and reliability decisions.

Maintenance Planning and Scheduling
strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section explains how dedicated planning and weekly scheduling convert incoming work into prepared, sequenced jobs. It covers the role definitions and rhythms that make it hold.

Maintenance Planning and Scheduling

The practice of using dedicated planners to prepare for maintenance work in advance by defining the scope, materials, tools, and labor required, and then coordinating with operations to schedule the work on a weekly basis.

Why it matters. Without real planning, technicians start jobs they cannot finish, so waiting and rework consume capacity and the shop stays reactive.

Myth

Planning is something supervisors and senior technicians can do alongside their regular duties.

Reality

Planning only works when planners are dedicated and separated from firefighting, since a part-time planner gets pulled into breakdowns and prepares nothing. Scheduling then commits to a weekly plan agreed with operations, which is what protects the planned work.

Tools for this
The least you need to know
  • Dedicated planners are the deciding factor; part-time planning is the usual failure mode.
  • A weekly schedule agreed with operations is what turns a plan into protected work.
  • Planning depends on clean work order data, so fix the work order system first.

strong · 1 source
  • Benchmarking Best Practices in Maintenance Management
In this section

This section covers how to build a PM program that targets the right equipment and actually gets done. You get coverage and compliance as the two measures that tell you whether it works.

Preventive Maintenance (PM) Program

A system of planned maintenance activities, including inspections, lubrication, and adjustments, designed to improve equipment life and avoid unplanned failures. Its effectiveness is measured by its coverage of critical equipment and its on-time completion rate.

Why it matters. A PM program that is too thin leaves critical equipment to fail, while one that is bloated or unfinished burns labor without preventing anything.

Myth

More PM tasks always mean fewer failures.

Reality

PM value depends on matching tasks to failure modes of critical equipment and completing them on time. An overloaded PM schedule that is routinely skipped or does intrusive work on healthy equipment can add failures through human error.

Tools for this
The least you need to know
  • Coverage of critical equipment and on-time completion are the two numbers that define PM health.
  • PM tasks should be tied to failure modes, not to habit or vendor defaults.
  • Inspection findings are the PM program's main output, because they create the planned work that replaces breakdowns.

  • Benchmarking Best Practices in Maintenance Management
In this section

This section covers how to run the storeroom and purchasing so the right parts are on hand without overstocking. It focuses on record accuracy and who decides what is stocked.

Maintenance Inventory and Purchasing Control

The set of practices for managing maintenance materials and spare parts to ensure high availability (service level) while minimizing inventory holding costs, supported by accurate records and maintenance control over stocking decisions.

Why it matters. Poor control produces the worst combination: capital tied up in parts nobody uses and stockouts on the parts that stop production.

Myth

A bigger spare parts inventory is the safest way to guarantee availability.

Reality

Availability comes from stocking the right items with accurate records and controlled min/max levels, not from volume. Surplus stock hides inaccurate records and obsolete items while critical parts still go missing.

Tools for this
The least you need to know
  • Accurate records and controlled stocking decisions matter more than total inventory value.
  • Service level and holding cost must be managed together, not traded off by instinct.
  • Tying parts issues to work orders turns the storeroom into a source of usable demand data.

In this section

This section lays out how to train craft technicians, planners, and supervisors on both technical and interpersonal skills. It shows how to make training a continuing system rather than an event.

Maintenance Training

The formal and ongoing process of developing the technical and interpersonal skills of maintenance personnel, including craft technicians, planners, and supervisors, to ensure they can effectively maintain increasingly complex equipment.

Why it matters. Under-skilled crews take longer, make repeat repairs, and cannot cope with new equipment, which drags down productivity and reliability.

Myth

Training is a cost to cut first when budgets tighten because skilled people learn on the job anyway.

Reality

On-the-job learning passes along existing habits, including bad ones, and does not cover new technology or planning and supervisory skills. Without structured training, rework and slow troubleshooting quietly erode wrench time.

Tools for this
The least you need to know
  • Planners and supervisors need training as much as technicians do.
  • Training should be tied to a skills-gap assessment, not to whatever course is on offer.
  • The payoff shows up in shorter job times and fewer repeat repairs.

Asset Availability and Reliability

How this mechanism is run, step by step, as the literature describes it.

  1. 1Name the key assets, processes and facilities whose availability you will track. The survey scores 'overall equipment availability calculated on key assets, processes, and facilities' in bands: 90% or more scores 4, 60 to 89% scores 3, 30 to 59% scores 2, and under 30% scores 0. Coverage is the first thing to fix, and the passages do not define a coverage-first cutoff beyond these bands.
  2. 2Make every job traceable to an asset. Score yourself on the share of work orders tied to an equipment/asset number, the share of jobs covered by a work order, and the share of man-hours reported to a work order (100% scores 4, 75% scores 3, 50% scores 2). Without this, uptime and failure counts cannot be attributed to an asset.
  3. 3Record required downtime on each work order. The survey awards a point for tracking it, alongside craft hours, materials and requestor. Downtime per asset is the raw input for any availability figure.
  4. 4Capture failure cause, not just the repair. Score what share of an asset's work order history accurately tracks causes of failure and clearly identifies failures (90% or more scores 4, under 40% scores 0). The source warns that chronic problems stay hidden, and that only accurate records reveal them and allow the root cause to be solved using maintenance and financial data together.
  5. 5Run failure analysis with a defined tool (why tree, fishbone, Pareto) so the work is accurate and consistent. Use the results to adjust the PM/PdM program through RCM. RCM needs complete, accurate asset data: 90% or more of assets scores 4.
  6. 6Match inspection technique to criticality. Predictive maintenance covers vibration analysis, thermography, oil analysis and sonics, scored 4 for critical and non-critical assets, 2 for critical only, and 0 for none. Tie the data to the CMMS (integrated 4, interfaced 3) so findings generate PM or corrective work orders, and schedule predictive work in the weekly plan.
  7. 7Put the cost in front of decision-makers. Price each outage as repair cost plus lost production (the source's average is 4:1). Communicate this to everyone, and use availability in operational decisions (90% or more of the time scores 4).
  8. 8Hold a joint operations/maintenance priority meeting weekly (scores 4; daily scores 2). Include maintenance in production scheduling meetings, and check that the share of emergency/urgent work orders stays under 20% (scores 4).

Checklists

Checklistfree

Asset Availability and Reliability — decision rules

  • If the emergency/urgent share of work orders is 20% or more, treat availability as a planning problem first. Fix priority-setting and PM coverage before buying more monitoring. Under 20% is the top survey band.
  • If a repair is justified only against its labor-and-materials invoice, restate it at the lost-production-inclusive cost (average 4:1) before approving or rejecting preventive or predictive spend.
  • If asset history lacks failure causes or equipment numbers, do not compute or compare MTBF-style figures yet. Fix the records first, since chronic problems stay hidden without them.
  • If maintenance reports to production, check whether supervisor pay is based only on throughput. If so, expect maintenance to turn into firefighting, unless availability or life-cycle cost targets are added to their compensation.
  • If maintenance reports to engineering and a project is running late, check whether PM labor is being diverted to project work. The source warns that existing equipment then suffers from lack of maintenance.

Asset Availability and Reliability

Context

The source's own example: a maintenance repair costs $10,000 in labor and materials, but the real cost is closer to $50,000 once lost production is counted. The gap, roughly $40,000, is lost production, so the outage costs about five times the invoice. That matches the source's statement that the average ratio is usually 4:1. Suppose the repair sits on a work order tied to an asset number, with required downtime recorded and the failure cause logged. Then it can feed a Pareto of failures for that asset, and the root cause can be pursued with a why tree. A manager who sees only the $10,000 cuts the inspection that would have caught the fault. A manager who sees $50,000 compares it with the cost of vibration, thermography or oil analysis on that asset. The source adds that downtime is more costly than maintenance expenditure, and that any time gained in repairs becomes reduced downtime or increased availability.

Case study◆ Paid

Disciplined Work Order System

Context

The book's own audit (Section 3, Maintenance Work Orders) works as a scorecard. Suppose a plant finds that about 75% of man-hours are reported to work orders (3 pts), 50% of materials are charged to a work order number at issue (2 pts), and 75% of jobs are covered by work orders (3 pts). Every work order is tied to an asset number (4 pts), but 35% are opened as emergency or urgent (2 pts, the 30-39% band). The plant then sees a pattern: the missing materials and the missing hours mean the cost of a job can never be fully known. The plant closes the materials gap first by requiring a work order number at the storeroom before any issue. It then moves the jobs and man-hours toward 100% by refusing time entries without a work order number. Next it adds a quality check on every completed order, and it records downtime, craft hours and materials as tracked categories. Over time the emergency share should fall below 20% as planning reaches the 80% weekly target and schedule compliance reaches 90%. The audit is then repeated to confirm the scores moved.

Maintenance Cost-Effectiveness

Context

The source's own figures give a worked waste calculation. A craftsperson paid about $20.00/hour is on the clock 8 hours, but hands-on time is under 4 hours, and often 2. At 4 hours of use the resource runs at 50%, so about $80 of an $160 day is non-productive. The cause is not laziness; the source says craftsmen are not given the resources to do the tasks. Next, apply the planning ratio: a $100 planned job could cost as much as $500 unplanned, so moving 10 jobs from unplanned to planned would save up to $4,000 on the source's 1:5 ratio. Then check the macro indicator. If maintenance runs at a stable percentage of production cost and it suddenly moves, you examine maintenance efficiency and effectiveness for the cause. The source also notes that one-third of the 1979 US spend of over $200 billion was wasted, and that the waste ratio likely still holds. Treat that as the baseline assumption for an unaudited program.

Maintenance Inventory and Purchasing Control

Context

The passages give a cost case. A site has a $1 million maintenance inventory. At a carrying cost of over 30% of price per year, it costs over $300,000 annually to hold. The common reaction to a materials problem is to overstock the storeroom, which raises that cost without fixing the control problem. Instead, the manager scores the storeroom against the Section 6 questions. Suppose the audit shows materials in stores when needed only 70 to 79% of the time (2 pts), max/min specified on under 70% of items (0 pts), and someone outside maintenance deciding what to stock (0 pts). The sequence is: first take stocking control into maintenance, then set max/min on every item, then protect critical items in an accessible location, then verify daily receipt updates and work-order issue coding. Stocking decisions now follow actual issue history, not a blanket increase in stock. The passages show the stakes of getting this right. Materials run 40% to 60% of the maintenance budget, and lost production can cost two to fifteen times a repair, 4:1 on average. A $10,000 repair that waits on a missing part is really closer to $50,000. The stock-versus-carry tradeoff is therefore judged against downtime cost, not just the carrying rate.

Maintenance Labor Productivity ('Wrench Time')

Context

Wireman's foreword gives the figures. A craftsman is paid for 8 hours a day at roughly $20.00 per hour, but spends fewer than 4 of those hours on hands-on work. 4 ÷ 8 is 50% wrench time, so about $80 of each $160 daily labor cost buys no direct work. In the majority of organizations the figure drops to 2 hours: 2 ÷ 8 = 25%, which leaves $120 of $160 unproductive per technician-day. Wireman is explicit that these craftsmen 'are not lazy' and are 'not provided the necessary resources by management.' So you do not start by pressuring technicians. You split the lost hours into parts waits, instruction waits, and travel, then fix the biggest bucket. The source ties the fixes to planning and scheduling: 80-90% of work planned weekly, 90% schedule compliance, and a planner role. It also notes that a reactive organization with good planning and scheduling may raise wrench time, though the passage cuts off before giving the target figure. The measurable result is the percentage rising from the baseline and the daily dollar loss falling.

Maintenance Materials Availability

Context

The source's own figures can be run as a two-sided test. Suppose a breakdown repair costs $10,000 in labor and materials. At the 4:1 average, the real cost with lost production is about $50,000. If the repair stalls because a $200 part is not in the storeroom, the delay is judged against that $50,000 exposure, not against $200. Now take the opposite fix, overstocking. A $1 million inventory costs over $300,000 a year to carry (30%+). The tradeoff is therefore not 'more stock is safer.' Each added dollar of stock costs about 30 cents a year, and each avoided stock-out saves a multiple of the repair cost. The expert move is to identify which items sit on the critical assets and stock those to a service level. Then use work-order issue history (100% of issues charged to a work order, 100% tied to an asset) to find the rest. Reduce the remaining inventory while watching stock-outs, overtime, and hands-on time.

Maintenance Planning and Scheduling

Context

Wireman's survey statistics show why planning pays. Craftsmen spend fewer than 4 of 8 hours per day on hands-on work, and in many organizations as little as 2 hours. The cause is that management does not provide the resources they need, not laziness. At roughly $20.00 per hour, a craftsman used at 50% wastes about half of that paid hour. Only about one-third of organizations employ a job planner, even though experts see planner use as one of the largest cost-saving opportunities in maintenance. Planned work versus unplanned work may have a cost ratio as high as 1:5. In practice, this means a job that costs $100 when planned can cost up to $500 when handled reactively. An organization scoring itself on Section 4 might find that craft technicians plan their own jobs (0 points), schedules are issued daily (1 point), and plans cover only craft and materials (2 points). Moving to a dedicated planner, weekly schedules, and a full four-element plan would lift each of those items to 4 points.

Maintenance Training

Context

The Foreword describes a pattern that shows what training addresses. Preventive maintenance is often reduced to lube routes. Almost three-fourths of organizations have lube routes and procedures, but the oiler position is generally entry-level, and the technician's lack of proper skills and training often leads to substandard performance and excessive breakdowns despite the program. Apply the audit to a plant in this position. Lubrication staff have OJT only, which scores 1 on craft training. Planners learn on the job, which also scores 1. Supervisors get optional training, which scores 3. Training reaches only some employees every two or more years, which scores 1 on intervals. Your first moves follow the scoring ladder. Give lubrication technicians a mixed classroom and lab course (4 pts on format), and move planners from 1 pt to 2 pts with at least a month of one-on-one OJT, then to a written program (3 pts). Make supervisor refreshers mandatory and scheduled (4 pts), and schedule all craft training at least annually (4 pts). Re-run the audit after a year to verify the points moved.

Management Support and Attitude

Context

The Foreword's own repair example shows the method. A maintenance repair is booked at $10,000 in labor and materials. Counting lost production at the typical 4:1 ratio, the real cost is closer to $50,000. A plant manager who sees only the $10,000 treats the repair as a cost to cap. Seen at $50,000, the same event is a failure that earlier planned work could have prevented. Pair this with the planned-versus-unplanned ratio of up to 1:5, where a $100 planned job becomes a $400-more unplanned one. Then compare it with the labor picture: at about $20.00 per hour and only about 50% utilization, the site pays full price for a resource it uses at half capacity because management has not supplied planners, parts, or systems. Presented together, these three numbers move the discussion from 'maintenance spends too much' to 'management has not funded the conditions that make maintenance spending effective.' Section 14 then gives a scored baseline: if visible management support rates 'weak' (2 points) instead of 'strong' (4), that gap becomes the first item on the action list.

Operations Involvement

Context

The source supplies the scoring frame, so this walks a plant through it. The scores below are illustrative inputs, not data from the source. A plant scores itself on Section 8. About 45% of operations personnel generate work requests (1 pt, the 40-59% band). Maintenance sets work-order priority with minimal operations input (1 pt). Operators are not responsible for asset upkeep (0 pts). Operators are trained and certified on only one task, inspections (1 pt). The plant compares its Section 8 total to the 22.2 average from more than 100 surveyed companies and sees a gap. It acts in this order: first, a weekly joint priority meeting, which moves that item from 1 pt to 4. Second, it names operators responsible for upkeep, moving that item from 0 to 4. Third, it trains and certifies operators on lubrication and routine adjustments, which adds points and returns maintenance hours. Those hours go to predictive work such as vibration analysis, which the source names as the next focus. The plant re-scores after each change and tracks the section against 22.2.

Overall Profitability

Context

The source's savings arithmetic: a company has a $3M annual maintenance labor budget. Applying the 1/3-waste estimate gives roughly $1M saved over time. The materials budget is typically a similar $3M, and a 1/3 reduction there brings total savings close to $2M per year. These are expense dollars not spent, so they become profit dollars. The savings need not come from headcount; they can come from less overtime, fewer outside contractors, or deferred maintenance done without extra spend. Capacity is the bigger lever. If equipment downtime runs 10 to 20% or more, product that could reach the market is lost. A company that buys backup or redundant equipment to cover that downtime lowers its return on net assets and its investment rating. In the source's real case, a compressor overhaul paid back in 28.1 days after restart, and $5.4M of increased production was realized in the next 12 months.

Preventive Maintenance (PM) Program

Context

The source's own survey figures show the pattern. About 22% of surveyed companies say PM meets their needs, and over three-fourths need major improvement. Almost three-fourths have lube routes and procedures, which looks positive, but the source warns that many organizations treat lubrication as the whole of PM and stop developing the program. Take a plant in that position. It has a lube route run by an entry-level oiler with little training, so breakdowns stay high despite the program. Following the source, the plant first widens PM to include inspections and adjustments. It trains the lubricator. It then routes inspection findings into work orders, aiming for 80-100% of work orders generated from PM inspections (the top score in the assessment). It plans each job with craft, materials, tools, and instructions, because a $100 planned job can save up to $400 against the unplanned version. It briefs operations/facilities on the benefits, since coordination fails in almost three-fourths of organizations. Overtime, 14.1% on average, is the check on whether the work is moving from reactive to proactive.

Proactive Maintenance Orientation

Context

The source's savings illustration starts with a maintenance labor budget of $3M annually. Studies show the materials budget is a similar amount, so total maintenance spend is roughly $6M. The source's claim is that if labor efficiency improves by about one-third (through less overtime, fewer outside contractors, and deferred maintenance done without added spend) and materials are also cut by one-third, total savings could approach $2M per year. These are expense dollars not spent, so they flow to profit. The savings are not headcount cuts and are not immediate: moving from a reactive to a proactive, best-practice organization takes three to five years. The larger payoff is availability. If equipment downtime runs 10 to 20% in a company, recovering that capacity outweighs the pure maintenance savings, and avoids buying redundant backup equipment that hurts return on net assets.

The book, examined

Not a summary — a close analytical reading: how the book is built, what it leaves open, and where it falls short.

How it’s built — the argument in order

  1. 01
    The Cost of Reactive Maintenance — Establishes the problem — quantifying the roughly one-third of maintenance spending wasted through reactive practices, framing maintenance as a squandered trillion-dollar opportunity and motivating the transformation thesis.
  2. 02
    Self-Assessment Survey — Provides a diagnostic instrument for managers to score their organization's current state across the core maintenance constructs, answering the 'where am I now' question before improvement can begin.
  3. 03
    Principles of Benchmarking — Lays out the fundamental method — how to benchmark against best-in-class organizations, emphasizing adapting processes over chasing raw numbers, positioning benchmarking as the engine of continuous improvement.
  4. 04
    Core Process Best Practices — The bulk of the book — sequential deep dives into organization, training, work order systems, planning/scheduling, preventive maintenance, and inventory/purchasing control, presented as an interconnected system built in disciplined order from foundation upward.
  5. 05
    Linking Maintenance to Profitability — Connects operational improvements to financial outcomes — showing how asset availability and cost reduction feed metrics like Return on Fixed Assets, reframing maintenance from cost center to profit contributor.
  6. 06
    KPIs and Management Reporting — Closes with the control layer — the performance indicators and reports needed to sustain gains, analyze wrench time, materials availability, and reliability over time.

What it leaves unsolved

How does an organization overcome cultural and political resistance to abandoning firefighting as a mode of operation?

The book prescribes a disciplined sequential transformation and stresses management attitude, but the change-management mechanics of shifting entrenched reactive habits are named as a construct rather than operationalized.

How reliable is the one-third-wasted / trillion-dollar figure, and how does it apply to a specific plant?

The headline motivation rests on an aggregate estimate; the book uses it rhetorically but does not show how a given manager verifies the waste level in their own operation beyond the self-assessment.

How should benchmarking be done when comparable best-in-class peers are unavailable or won't share data?

The method assumes access to world-class organizations' processes, but the practical barrier of finding and accessing genuine benchmark partners is not resolved.

How does the framework scale across industries with radically different asset profiles (e.g., continuous process vs. discrete manufacturing vs. facilities)?

Best practices are presented largely generically; the book admits maintenance is context-dependent yet leaves industry-specific tailoring to the reader.

What is the sequencing when resources are too scarce to master the 'basics' first?

The disciplined-order thesis assumes an organization can invest in foundations before advanced techniques, but doesn't address organizations lacking capital or staffing for even the foundational work order system.

Where it falls short — a fair critique

incomplete

The book identifies management support and attitude as a critical construct but treats it more as a precondition than a problem it solves — it offers processes and tools while under-supplying the persuasion and change-leadership tactics needed to secure that support.

uninformed

The reliance on benchmarking best-in-class companies presumes those exemplars' practices transfer, but the book gives limited attention to the survivorship and context bias in benchmark data — successful practices may be entangled with conditions the reader cannot replicate.

misinformed

The framing of maintenance as directly driving 'overall profitability' via ROFA risks overclaiming causality; availability and cost improvements are contributors among many variables, and attributing profitability shifts to maintenance can overstate its isolated impact.

illogical

The insistence on a strictly sequential 'master basics before advancing' path sits in tension with the claim that the practices form an interconnected system — interdependent systems often require parallel, iterative development rather than a linear build-order, and the book does not reconcile this.

incomplete

The self-assessment survey and KPI apparatus generate diagnosis and measurement, but the book underspecifies how to prioritize among simultaneous weaknesses when a plant scores poorly across many dimensions at once.

Before you apply it

Using it well

Where the method fits, who it’s for, and the honest case for and against — so you apply it where it works.

Is this book for you?

For you if

  • You manage or reform a maintenance department in an asset-intensive facility
  • You want a structured, sequential framework rather than isolated tips
  • You need to justify maintenance to corporate leadership financially

Skip it if

  • You run a lightweight operation with no significant physical assets
  • You already operate a mature proactive maintenance system
  • You want deep coverage of predictive/condition-monitoring technology

Need first

  • Basic understanding of maintenance operations and terminology
  • Authority or management backing to change work processes
  • Access to current maintenance cost and performance data for self-assessment

When it applies — and when it doesn’t

Use it
  • Asset-intensive plant with reactive, firefighting maintenance culture — exactly the reactive-to-proactive transformation this book targets
  • Establishing a work order system as foundation before planning — book treats disciplined work orders as the prerequisite base
  • Building a preventive maintenance and inventory control program — core processes covered in depth with best practices
  • Justifying maintenance investment to finance via profitability link — ROFA framing connects maintenance to corporate metrics
Adapt it
  • Benchmarking against best-in-class organizations — value is in adapting processes, not copying numerical targets
  • Small non-asset-intensive or service-only operation — framework assumes physical assets and maintenance departments
  • Culture where management gives no support for maintenance discipline — transformation depends on management attitude and operations involvement
  • Predictive/condition-based maintenance deep-dive — book emphasizes basics over sophisticated diagnostics
Not here
  • Skipping fundamentals to adopt advanced predictive techniques — book insists on mastering basics sequentially first
  • Chasing KPI dashboards without process change — metrics without underlying process discipline mislead

The honest case

Strongest case for

  • A trillion-dollar waste estimate makes the improvement stakes large and concrete
  • Interconnected-system view prevents piecemeal fixes that fail in isolation
  • Sequential discipline (work orders → planning → PM → inventory) mirrors how real maturity builds
  • Linking maintenance to ROFA reframes it from cost center to profit lever, aiding buy-in
  • Self-assessment plus benchmarking gives a repeatable diagnostic path to improvement

Strongest objection

  • Best-practice frameworks can become checklist compliance without genuine culture change
  • Waste figures and benchmarks may not translate across industries or company sizes
  • Emphasis on basics may undersell modern predictive and IoT-driven maintenance
  • Sequential prescription can be slow where competitive pressure demands faster gains

How to measure it

Turning each idea into a measure

For each construct: how to operationalize it, the observable signals to look for, and how well it holds up.

Disciplined Work Order System

Measured as the percentage of total maintenance man-hours reported to a work order; the percentage of maintenance materials charged against a work order; and the percentage of total jobs covered by work orders. Best practice is 100% coverage for all three.

Observable signals
  • Existence of a formal work order form (paper or electronic).
  • All technicians receive assignments via a work order.
  • No material is issued from stores without a work order number.
  • A historical file of completed work orders is maintained for each asset.
Scale

Archival data analysis of work order database or logs.

Maintenance Planning and Scheduling

Measured by the ratio of maintenance planners to hourly employees (target 1:15-20), the percentage of work that is planned versus unplanned, and the weekly schedule compliance rate (percentage of scheduled work completed).

Observable signals
  • Presence of dedicated maintenance planner roles.
  • Publication of a formal weekly maintenance schedule.
  • Regular (weekly) scheduling meetings between maintenance and operations.
  • Availability of a documented work backlog report by craft.
Scale

Archival data from CMMS (schedule compliance reports, backlog reports).

Preventive Maintenance (PM) Program

Measured by the PM compliance rate (percentage of scheduled PM tasks completed within a specified window of the due date, e.g., 1 week), and the percentage of critical plant equipment covered by the PM program. Best practice for both is 90% or more.

Observable signals
  • Existence of detailed PM checklists and procedures for critical equipment.
  • PM tasks appear on the weekly work schedule.
  • Generation of corrective work orders resulting from PM inspections.
  • Dedicated PM personnel or specific PM assignments for crews.
Scale

Archival data from CMMS (PM overdue reports, PM completion statistics).

Maintenance Inventory and Purchasing Control

Measured by the stores service level (percentage of time materials are in stock when required; target >95%), inventory turnover rate, and total inventory value as a percentage of the plant's Estimated Replacement Value (ERV; target ~1%).

Observable signals
  • A formal stores catalog exists.
  • Aisle/bin locations are specified for most items.
  • Max/min levels are set for inventory items.
  • Maintenance is consulted on or controls what items are stocked.
Scale

Archival data from inventory management system.

Maintenance Training

Measured by the annual training expenditure per employee, training budget as a percentage of total payroll, and the frequency at which formal maintenance training is provided to all craft employees.

Observable signals
  • Existence of a formal training and progression program.
  • Regularly scheduled training sessions (classroom or lab).
  • Budget allocated specifically for maintenance training.
  • Records of completed training for each employee.
Scale

Archival data from HR and financial records.

Operations Involvement

Measured by the percentage of operators trained and certified to perform basic maintenance tasks (e.g., inspections, lubrication, minor adjustments) and their participation in weekly maintenance scheduling meetings.

Observable signals
  • Operators are observed cleaning and inspecting their equipment.
  • Operations supervisors attend weekly maintenance scheduling meetings.
  • A high percentage of work requests originate from operations personnel.
  • Existence of a formal Total Productive Maintenance (TPM) or similar initiative.
Scale

Survey and perceptual data from maintenance and operations staff; archival data on work order originators.

Management Support and Attitude

Measured through perceptual surveys asking whether the maintenance function is perceived as value-added by management, whether management supports continuous improvement efforts, and whether maintenance priorities (like PM) are respected during production pressures.

Observable signals
  • Management consistently protects scheduled maintenance windows from production encroachment.
  • Funding is approved for maintenance improvement projects (e.g., CMMS, training, predictive tools).
  • Maintenance is included in strategic plant-level meetings.
  • Management speaks about maintenance in terms of reliability and contribution, not just cost.
Scale

Perceptual data from surveys of maintenance and operations personnel.

Proactive Maintenance Orientation

Measured as the ratio of proactive (planned, scheduled, PM, PdM) maintenance hours to reactive (emergency, breakdown) maintenance hours. Best practice is a ratio of at least 80:20.

Observable signals
  • Low percentage of work orders with 'emergency' or 'urgent' priority (<20%).
  • A stable weekly work schedule that is largely adhered to.
  • Low levels of maintenance overtime (average < 5%).
Scale

Archival data from CMMS work order history.

Maintenance Labor Productivity ('Wrench Time')

Measured through direct observation or work sampling studies to determine the percentage of an 8-hour day spent on direct work activities. Reactive organizations are often at 25-35%, while best practice organizations achieve 50-60%.

Observable signals
  • Technicians arrive at the job site with all necessary parts and tools.
  • Minimal time is spent waiting for equipment to be released by operations.
  • Technicians are not observed loitering or making multiple trips for one job.
Scale

Behavioral observation (work sampling).

Maintenance Materials Availability

Measured by the storeroom service level, calculated as the percentage of requested items that are available in stock at the time of request. Best practice is a service level of 95% to 97%.

Observable signals
  • Low number of stockout reports.
  • Maintenance technicians express confidence in the storeroom.
  • Reduced instances of technicians creating personal 'squirrel stores' of parts.
Scale

Archival data from inventory management system.

Asset Availability and Reliability

Measured by a combination of metrics including: percentage of equipment uptime, Mean Time Between Failures (MTBF), and Overall Equipment Effectiveness (OEE), which combines availability, performance rate, and quality rate.

Observable signals
  • High OEE scores.
  • Low levels of production delays attributed to equipment failure.
  • Production schedulers have high confidence in equipment availability.
  • Lengthening trend in MTBF for critical assets.
Scale

Archival data from CMMS and production control systems.

Maintenance Cost-Effectiveness

Measured as the total annual maintenance cost (labor, materials, contractors) as a percentage of the Estimated Replacement Value (ERV) of the facility's assets. Best practice is typically 2-3%.

Observable signals
  • Maintenance costs are stable or declining as a percentage of ERV.
  • The maintenance department consistently meets or beats its budget.
  • The ratio of maintenance cost to production output is favorable compared to benchmarks.
Scale

Archival data from financial accounting systems and CMMS.

Overall Profitability

Measured by high-level corporate financial metrics such as Return on Fixed Assets (ROFA), Return on Net Assets (RONA), or Earnings Before Interest and Taxes (EBIT).

Observable signals
  • High ROFA compared to industry competitors.
  • Strong profit margins.
  • Reduced need for excess capital investment in redundant equipment.
Scale

Corporate financial statements.
