  • Five-minute Deming: Quality before inspection

    Five-minute Deming: Quality before inspection
    2026/04/01
    Many leaders think inspection is what protects quality. If defects slip through, the answer seems obvious: add another check, another review, another pair of eyes at the end. It feels careful. It feels responsible.But that habit can quietly raise cost, normalize rework, and keep management from seeing the deeper problem. The real issue is not what we catch at the end. It is what our system keeps producing in the first place.The management trapOne of the easiest mistakes in management is to confuse detection with improvement. When something goes wrong, we naturally look for a way to catch it sooner, sort it faster, or keep it from reaching the customer. That instinct is understandable. It is also incomplete.A company can become very good at finding defects and still remain trapped in a weak process that keeps making them. W. Edwards Deming said it plainly: “[Using] inspection to improve quality is too late, ineffective, costly.”[Using] inspection to improve quality is too late, ineffective, costly.— W. Edwards DemingThe force of that statement is easy to miss. He was not arguing against all inspection. He was arguing against the belief that inspection is where quality is achieved.Quality is shaped upstream, in design, methods, training, maintenance, scheduling, and in the way management coordinates the whole system.To see how easily leaders drift into the opposite habit, consider a small manufacturer that had become highly disciplined at catching defects and surprisingly tolerant of producing them.A small manufacturer, a familiar patternHartwell Fixtures made custom metal display racks for local retailers. It was a solid Main Street manufacturer with a good reputation and steady orders. Elena, the owner, took pride in the fact that every rack was inspected before shipment.From a distance, that looked like discipline.On the floor, it looked different.Welds were sometimes rough. Powder coating occasionally bubbled. Mounting holes did not always line up. None of those issues alone threatened the business. But together, they created a constant drag on the work. Final inspection kept finding defects, and rework kept absorbing time, attention, and overtime.When a shipment was late for the third time in a month, Elena walked into inspection and saw what had gradually become normal: carts full of rework, operators waiting for decisions, and inspectors arguing over borderline pieces.“What’s the fastest way to get this back under control?” she asked.Marcus, her operations manager, answered with the logic the company had been living inside for months.“We are catching most of the bad units,” he said. “If we add one more inspector on second shift, we can clear the backlog.”That answer was practical. It was also revealing.More inspection had already been the answer for months. Yet the backlog remained. Scrap was up. Overtime was up. Customers were becoming less patient. Hartwell was not dealing with a few isolated mistakes. It was operating inside a predictable system.Later that day, Elena and Marcus looked at the recurring defects together. One week the problem centered on drilling. Another week it was coating. Another week it was warped tubing from a supplier. The pattern moved around, but the burden stayed in the same place: at the end, where the company tried to sort, repair, and rescue what the system had already produced.Deming captured that logic memorably: “Our system of make-and-inspect, if applied to making toast, would be expressed: ‘You burn, I’ll scrape.’”Our system of make-and-inspect, if applied to making toast, would be expressed: ‘You burn, I’ll scrape.’— W. Edwards DemingThat was Hartwell’s system in miniature. Make the rack. Find the defect. Grind it. Redrill it. Recoat it. Expedite it. Apologize for it. At some point, the company had confused recovery with quality.That realization changed the conversation.“If inspection is our main defense,” Elena said, “then we are planning to make defects.”“Then where do we start,” Marcus asked, “if not at the end?”Instead of asking how to strengthen the inspection wall, Elena and Marcus started tracing the defects upstream. They found fixture wear at the drilling station. They reviewed variation in incoming tubing from one supplier. They discovered that a setup shortcut had become normal on busy days. They also saw coating problems rise when rushed scheduling changes caused parts to sit too long between steps.Inspection did not disappear. But it changed purpose. It became feedback about the process, not the company’s main theory of quality.Marcus began tracking defect patterns to learn where the system was unstable. Supervisors stopped treating rework totals as proof that quality control was working. Elena stopped celebrating heroic saves that depended on overtime and last-minute sorting.The result was not perfection overnight. Some defects still appeared. But rework began to shrink. Lead times became ...

  • Five-minute Deming: "Common sense"

    Five-minute Deming: "Common sense"
    2026/03/25
    In many organizations, the phrase “use common sense” sounds perfectly reasonable. A mistake happens, a customer complains, or a process fails, and the instinctive response is to remind people to slow down and think.But this familiar management reflex can quietly prevent improvement. When leaders rely on “common sense” explanations, they often focus on the individual closest to the problem instead of the system that produced it.W. Edwards Deming warned that this habit does more than miss the cause—it can keep organizations trapped in the very patterns they are trying to fix.Why “common sense” fails in managementMost managers have experienced the moment when something goes wrong. A customer receives the wrong order, an appointment is missed, or a deadline slips by.The explanation appears obvious: someone made a mistake. Our instinct is to correct the person involved—remind them to be careful, encourage better judgment, or send a note to the team about paying closer attention.These responses feel practical because work is done by people. But Deming argued that most recurring problems do not originate with individual effort or attention.They are produced by the way work is designed—the methods, priorities, handoffs, and pressures that shape everyday decisions. When leaders overlook that reality, the same cycle repeats: correct the person, see temporary improvement, and then watch the problem return.A small service company illustrates how easily this pattern develops—and what changes when a leader begins looking at the system instead.A scheduling problem that kept returningMaria owns a home services company that schedules technicians for repairs and installations across her city.Over several months, customer complaints began to increase. Appointments were occasionally missed, technicians sometimes arrived without the right parts, and a few customers reported waiting all day for a visit that never appeared on the schedule.One afternoon a customer called after waiting five hours for a technician who never arrived. Maria reviewed the call recording and quickly discovered the problem: the job had been placed into the wrong time slot.It looked like a simple scheduling error.Later that day she spoke with her operations supervisor, David.“This one should have been obvious,” Maria said. “People just need to slow down and use some common sense when they’re entering these jobs.”David agreed the mistake appeared straightforward, and the team reminded dispatchers to double-check their entries. For a short time the complaints seemed to ease.But two weeks later another scheduling problem surfaced. Then another.While reviewing scheduling logs, David noticed something unusual. The same type of error appeared across different dispatchers and across different shifts. It did not look like one employee being careless.The team began examining the scheduling process itself. Service requests arrived through phone calls, website forms, and callbacks from technicians in the field.The information customers provided varied widely, and dispatchers often had to guess which technician should handle a job. At the same time they were expected to answer calls quickly while entering appointments into the system.During busy periods dispatchers were juggling two demands at once: respond to customers immediately and figure out incomplete job details. The errors appeared most often when call volume spiked and dispatchers rushed to keep up.Deming described this common management reaction in The New Economics: “Common sense [mistakenly] tells us to speak to the operator about it when a customer reports something wrong with a product or with a service. ‘We have spoken to the operator about it; it won’t happen again.’”Common sense [mistakenly] tells us to speak to the operator about it when a customer reports something wrong with a product or with a service. ‘We have spoken to the operator about it; it won’t happen again.’— W. Edwards DemingMaria realized her earlier response had followed exactly that pattern. She corrected the person closest to the problem while leaving the process unchanged.The team redesigned the scheduling system. They standardized intake questions so dispatchers received consistent information, clarified which technician handled each type of job, and adjusted call targets so dispatchers were not forced to rush scheduling decisions.Within weeks the number of scheduling problems began to fall—not because employees suddenly became more attentive, but because the system guiding their work had improved.As Deming wrote: “Action taken today may only produce more mistakes tomorrow. It may be important to work on the process that produced the fault, not on him that delivered it.”Action taken today may only produce more mistakes tomorrow. It may be important to work on the process that produced the fault, not on him that delivered it.— W. Edwards DemingWhy leaders blame people ...

  • Five-minute Deming: Annual performance reviews

    Five-minute Deming: Annual performance reviews
    2026/03/18
    Most organizations rely on annual performance reviews to evaluate contribution, allocate rewards, and create accountability. The logic feels straightforward: measure results, rate people, and recognize the strongest performers. For decades, this ritual has been treated as a basic tool of management.But what if the very practice meant to improve performance quietly prevents real improvement from happening?W. Edwards Deming believed annual performance reviews were not merely ineffective. He argued they were one of the most damaging management practices in modern organizations because they direct leadership attention toward judging individuals instead of improving the system that produces results.To understand why, we have to rethink what actually creates performance in the first place.Why Deming challenged performance appraisalsLeaders want to understand how well their organizations are performing. That instinct is healthy; good leadership requires visibility into results and a clear understanding of where improvement is needed.Annual performance reviews promise a structured way to do this. They compress a year of work into scores, ratings, and rankings that guide compensation, promotion, and recognition.But Deming argued that this approach misunderstands how organizations actually produce results. He wrote: “Basically, what is wrong is that the performance appraisal or merit rating focuses on the end product, at the end of the stream, not on leadership to help people.”Basically, what is wrong is that the performance appraisal or merit rating focuses on the end product, at the end of the stream, not on leadership to help people.— W. Edwards DemingIn other words, reviews judge outcomes after the work is finished rather than improving the conditions that produce those outcomes in the first place. This difference—between judging results and improving the system that creates them—sits at the heart of Deming’s philosophy of management.To see how this dynamic unfolds in practice, consider the experience of a school district wrestling with teacher evaluations.A school district confronts the problemIn the Brookfield School District, evaluation season arrived every spring with predictable tension.Teachers prepared documentation of their work while principals conducted classroom observations. District administrators compared performance scores across schools, and those numbers shaped pay increases, promotions, and professional reputations.Marcus Lee, principal of Brookfield Middle School, had participated in the process for years, and each cycle followed the same pattern. Teachers worried about their scores, principals debated ratings, and district leaders reviewed charts comparing one school to another.Yet the classrooms themselves seemed to change very little.During a district leadership meeting, Marcus raised the concern with Superintendent Elena Ramirez.“We keep having the same conversations,” he explained. “We review the ratings, we talk about who did well and who didn’t. But the classrooms themselves aren’t improving much.”Ramirez understood the frustration, but she also saw the system as necessary.“The reviews help us identify our strongest teachers,” she said. “Without them, how do we know who is performing well?”Marcus paused before answering.“That’s the problem,” he replied. “We think the scores explain performance. But most of the time they reflect the conditions teachers are working in.”He pointed to several examples. Some teachers had consistent collaboration time with colleagues, while others rarely had time to work together. Some classrooms included far more complex student needs, and others had significantly more curriculum support.The more Marcus studied the situation, the more he saw a pattern emerging.As evaluation season approached, teachers became cautious. Collaboration slowed, and fewer people experimented with new lesson ideas because trying something new carried personal risk when results were judged individually.The system was doing exactly what it was designed to do: judge individuals.But something else was happening as well. Teachers began protecting their own standing rather than sharing openly, and leaders spent hours debating scores instead of studying the conditions shaping learning—curriculum support, scheduling, classroom composition, and collaboration time.Slowly, the conversation shifted away from improving teaching and toward explaining ratings.Deming warned about this dynamic decades ago: “Merit rating rewards people that do well in the system. It does not reward attempts to improve the system.”Merit rating rewards people that do well in the system.It does not reward attempts to improve the system.— W. Edwards DemingThat comment stayed with Ramirez after the meeting. If the ratings were not revealing true performance, what should leadership be studying instead?The answer emerged as district leaders began examining the system ...
