But there is another factor that can determine whether a factory can consistently make your product correctly: the equipment used on the production line.

A process may look simple on paper, but if the equipment is poorly selected, under-capacity, difficult to maintain, or incapable of holding the required tolerances, quality problems can quickly appear.

In this episode, we discuss how production equipment affects product quality, consistency, and scalability.

We also look at when manual processes stop being reliable enough, how flexible equipment differs from dedicated machinery, why machine capacity needs headroom, and how servicing and spare-parts availability can become serious production risks.

Finally, we share two real manufacturing examples where equipment choices directly affected product quality.

What do we discuss?

• What drives the decision to invest in production equipment
  Production volume is one of the first considerations. Expensive machinery may make little sense for a few hundred units, but once volumes reach thousands or tens of thousands per month, automation can become much easier to justify. Manufacturers also need to consider equipment cost, cycle time, labour requirements, and the break-even point.
• Manual production versus machine process capability
  A manual operator may be able to perform a task correctly, but repeating the same operation thousands of times can introduce variation. Where tight tolerances and consistent output are required, properly specified machinery can provide much better process capability over long production runs.
• Flexible equipment versus dedicated machinery
  Some machines can be programmed and shared across many different products, spreading their cost across multiple projects. Other processes require dedicated equipment designed specifically for one product, material, or operation. The right choice depends on production volume, required accuracy, flexibility, and cost.
• Why production equipment is often under-specified
  Manufacturers and product companies naturally want to control capital spending, especially at launch. But equipment chosen only for expected initial volumes can quickly become a bottleneck if sales grow faster than forecast. Building some capacity headroom into the production setup can therefore be very important.
• The hidden impact of machine setup and changeover time
  Programmable machinery does not necessarily switch instantly from one product to another. Calibration, alignment, setup checks, and trial runs may all be required. If this time is overlooked, the factory can significantly overestimate its true production capacity.
• Why spare parts, servicing, and maintenance matter
  Paul shares an example of a pick-and-place robot operating in China that needed a replacement component from Italy. The lead time was six weeks. A machine may perform perfectly when running, but poor local support or unavailable spare parts can create serious production downtime. Preventive maintenance and serviceability therefore need to be considered before equipment is selected.
• When manual resin dispensing caused inconsistent quality
  One product required a very precise amount of resin to be applied into a cavity. Doing the job manually with a syringe resulted in bubbles, poor curing, overflow, and inconsistent quality. A general-purpose automated dispenser also struggled because the resin was too viscous, so the team ultimately sourced dedicated equipment specifically suited to the application.

…and more! Please consider listening to the episode to hear the full story.

For buyers, the obvious temptation is to take advantage of the lower price. But an unusually cheap quote can create problems later if the supplier realizes that it cannot make enough money on the order. The factory may push for a price increase once production is underway, reduce the resources allocated to the project, or look for less visible ways to cut its costs.

That can include material substitutions, reduced maintenance, weaker quality control, rushed production, or assigning less capable people to the account. Over several production runs, it can also lead to the kind of gradual deterioration Paul Midler famously described as “quality fade.”

There is another risk, too. If an aggressive quote is a symptom of deeper financial problems, the supplier may be struggling with cash flow, unpaid sub-suppliers, shrinking business, or even the possibility of closure.

Let’s discuss what very low Chinese factory quotes can tell you about a supplier, the warning signs buyers should watch for, and why relentlessly pushing a manufacturer’s margin down can ultimately work against you.

Mattel, Philips, Samsung, Fitbit, Peloton, and numerous hoverboard manufacturers all had products recalled after safety or reliability issues were brought to light. These companies had far more engineering, testing, and quality resources than most importers, yet critical risks were still missed or not addressed quickly enough.

In this episode of China Manufacturing Decoded, Adrian and Renaud look at the news stories, examining what went wrong in each case and, more importantly, what importers can learn from them.

Even products from major brands can suffer from serious safety and reliability problems. This episode examines six well-known failures involving Mattel, Philips, Samsung, hoverboards, Fitbit, and Peloton, revealing weaknesses in areas such as supplier control, material selection, long-term reliability testing, foreseeable misuse, and post-launch monitoring.

For importers, the key lesson is that contracts and compliance certificates are not enough. Safety-critical requirements must be enforced throughout the supply chain, products must be tested under realistic use and misuse conditions, and customer complaints must be treated as valuable quality data. Effective risk analysis, supplier oversight, reliability testing, and rapid corrective action can significantly reduce the likelihood of costly recalls and injuries.

The post 6 Major Product Failures and the Quality Lessons Importers Should Learn appeared first on QualityInspection.org.

Worn tooling, loose components, blocked filters, inadequate lubrication, and other forms of equipment deterioration can gradually affect process stability and product quality. By the time the machine finally breaks down, the factory may already have produced hours, or even days, of defective products.

Preventive maintenance helps factories identify and address these risks before they turn into costly production emergencies. It replaces unpredictable breakdowns with planned inspections, cleaning, servicing, and component replacement.

Join us as we explain how preventive maintenance can reduce defects, unplanned downtime, excess inventory, delayed shipments, and emergency repair costs. We also discuss how it works alongside 5S, process control, and factory automation to support more consistent manufacturing performance.

Episode Summary

• 00:00 – Why preventive maintenance matters
  Adrian introduces this CMD Gold episode and explains why factories with experienced employees and expensive machinery can still suffer from defects, delays, and lost production capacity.
• 01:10 – What happens when factories rely on reactive maintenance
  Renaud describes the typical cycle in a poorly managed factory: machinery is installed, operated until it fails, and then repaired under intense production pressure without the necessary spare parts or preparation.
• 03:06 – What preventive maintenance means
  Preventive maintenance replaces unexpected breakdowns with planned inspections, cleaning, servicing, and component replacement. Some downtime remains, but it occurs at a controlled and convenient time.
• 04:29 – Is preventive maintenance more expensive?
  An unexpected equipment failure can produce defective parts, disrupt production planning, create material shortages, leave workers idle, and shorten the useful life of the machinery. These costs are often far greater than the cost of planned maintenance.
• 07:42 – Daily, weekly, and usage-based maintenance
  Operators can perform simple daily checks such as cleaning filters and looking for oil leaks. Technicians can conduct more detailed weekly inspections, while other components should be serviced or replaced according to operating hours or production cycles.
• 11:52 – Why factories resist planned maintenance
  Production managers may be reluctant to stop machinery while orders are waiting. This can create conflict between production and maintenance teams and encourage factories to operate equipment until it fails.
• 13:05 – Maintenance skills and automation
  More advanced automation creates more potential points of failure and requires better-trained technicians. Factories should automate progressively and make sure each new system is reliable before adding further complexity.
• 15:32 – Capacity, inventory, and customer benefits
  Reducing unexpected downtime increases usable factory capacity. It can also allow the manufacturer to hold less protective inventory, offer shorter lead times, improve labor productivity, and deliver more reliably.
• 18:17 – Preventing defects and supporting process control
  Worn or damaged machinery may continue producing bad parts before anyone realizes something is wrong. Preventive maintenance, 5S, and process monitoring reinforce one another by revealing deterioration before it causes a major failure.
• 20:12 – Planned maintenance or emergency repairs
  Maintenance is unavoidable. A factory can either perform it according to a documented plan or wait until equipment breaks and employees, production schedules, and customers are already affected.

Takeaways

• Every factory pays for maintenance. Preventive maintenance determines when that cost is incurred and limits the disruption it causes.
• Machines can produce defects before failing. Equipment deterioration is therefore a quality risk as well as a downtime risk.
• Operators and technicians have different responsibilities. Operators can complete basic daily checks, while trained personnel handle more detailed servicing.
• Maintenance can be time- or usage-based. Replacement intervals may depend on days, operating hours, production cycles, or measured deterioration.
• Production pressure is a major obstacle. Factories frequently postpone maintenance because they do not want to stop a busy machine.
• Automation increases maintenance requirements. More advanced equipment introduces additional failure points and demands stronger technical capabilities.
• Good maintenance increases effective capacity. More reliable equipment improves output without necessarily requiring additional machinery.
• 5S, process control, and maintenance work together. Clean, controlled processes make developing problems easier to identify.

That is because technical validation confirms whether a product performs as designed. It does not always reveal whether the product feels intuitive, comfortable, responsive, or easy to use in real-world conditions.

Adrian and Paul Adams examine the gap between engineering compliance and user experience. They discuss how packaging can accidentally activate a product, why a safe surface temperature may still feel uncomfortably hot, and how controls, materials, setup instructions, and response times can make a technically sound product feel faulty.

The episode also explains why product teams should test early prototypes with independent users, observe how they interact with the product, and continue using it long enough to uncover frustrations that a specification or checklist may never capture.

Episode Summary

• 00:00:45 – How can a technically correct product still fail users?
  A product may meet every specification and pass all its technical tests while still feeling awkward, confusing, uncomfortable, or unreliable to the customer.
  Users do not experience engineering reports or test results. They experience how the product responds, how it feels in their hands, and whether they can understand and operate it easily.
• 00:02:02 – A specification is a checklist, not the complete product experience
  Specifications are effective for measurable requirements such as dimensions, voltages, timings, tolerances, and material hardness.
  However, requirements such as whether a grip feels comfortable, whether a product seems too heavy, or whether a control feels intuitive are much more subjective. These qualities cannot always be captured accurately with a single number.
• 00:03:27 – When packaging made a working product appear faulty
  Paul describes a battery-powered product that operators accidentally switched on while placing it into its packaging.
  By the time customers opened the box, the battery could be depleted. Their first impression was that the product was defective or had not been charged properly, even though it had functioned correctly during production.
  
• 00:04:35 – When the first solution created another usability problem
  The initial solution was to require users to hold the power button for two seconds.
  This prevented accidental activation during packing, but test users then reported that the product would not turn on. They expected it to respond immediately, as similar products did.
  The technical requirement had been met, but the behavior did not match user expectations.
• 00:05:40 – Fixing the packaging instead of compromising the product
  The team restored the short press required to turn on the product and instead modified the packaging.
  By removing two of the finger openings, operators and users could only lift the product from positions away from the power button.
  This prevented accidental activation without making the product feel unresponsive.
• 00:06:38 – Passing a safety requirement does not guarantee comfort
  A product may remain well below the maximum external temperature permitted by its safety specification but still feel unpleasantly hot during normal use.
  Paul gives the example of a kitchen product designed to remain at approximately 40°C, despite a permitted limit of 60°C. The product has a significant safety margin, but someone carrying it across a kitchen may still become uncomfortable and want to put it down.
  The product passes the requirement, but the experience may still be poor.
• 00:09:13 – Why usability is harder to validate than engineering
  Engineering problems often have clear answers. A circuit works, or it does not. A component is within tolerance or outside it.
  Usability is less clear. A product may feel comfortable to one user, too light or flimsy to another, and too heavy for someone else.
  The intended users, environment, physical abilities, expectations, and method of operation all influence whether the design provides an acceptable experience.
• 00:11:57 – Why user experience is underinvested during NPI
  Usability testing is often neglected because it can be difficult to specify, measure, budget, and validate.
  Companies developing new products may be willing to invest in engineering tests with objective pass-or-fail results, but hesitate to spend money creating early prototypes for subjective user trials.
  As a result, products may progress through development without enough evidence that intended users can operate them comfortably and intuitively.
• 00:14:13 – Why usability feedback often arrives too late
  Many teams wait until tooling, fixtures, and pre-production builds are complete before placing realistic products in users’ hands.
  At this stage, changing the shape, material, weight, controls, packaging, or internal design can be expensive and may delay production.
  A product can therefore pass every NPI checklist and phase gate while still failing when customers begin using it.
• 00:15:50 – Do not rely only on the people who designed the product
  Product owners and engineers already understand how the product is intended to work. This knowledge can prevent them from noticing instructions, controls, or behaviors that would confuse a new user.
  The product should be given to people who have never seen it before, ideally without detailed guidance.
  Observing what they try to do, where they hesitate, and what they misunderstand provides more useful evidence than asking the development team to evaluate its own design.
• 00:16:21 – The intended user changes what “good” means
  A powerful cordless vacuum cleaner may work extremely well but still be too heavy for an elderly user to lift, store, or operate.
  Similarly, Paul recalls a technically successful smartphone that was so smooth and slippery that he repeatedly dropped it and replaced it after a month.
  Neither product necessarily failed its specification. The problem was that its physical design did not suit the real user or operating conditions.
• 00:18:26 – What product teams should examine during usability testing
  Paul identifies several areas where technically compliant products commonly create a poor experience:
  – Response timing and delays
  – Missing or unclear visual and audible feedback
  – Buttons that are difficult to find or press
  – Controls that cannot be used while wearing gloves
  – Labels and serial numbers that are difficult to locate or read
  – Setup processes that are not intuitive
  – Instructions that assume too much prior knowledge
  – Materials, shapes, and weights that become uncomfortable during use
  These details may look minor during development but can strongly influence customer satisfaction and product reviews.
• 00:20:25 – Feedback must be clear, appropriate, and noticeable
  A product may beep, flash, or display a signal exactly as specified, but that feedback may still be ineffective.
  The sound may be too loud, too quiet, too high-pitched, too long, or simply irritating. A light may be difficult to see, and a delayed response may make users believe that nothing happened.
  Product feedback should be validated with representative users rather than selected only according to the development team’s judgment.
• 00:24:01 – Setup should be intuitive, and instructions should be easy to follow
  New or innovative products may not behave like products users already understand.
  The setup process should therefore be intuitive, or the instructions should explain it in language that ordinary customers can follow without specialist knowledge.
  Sending early products and draft instructions to independent users can reveal confusing steps before the product reaches the market.
• 00:25:33 – Product owners need to live with the product
  Using a product briefly is not enough to understand its complete user experience.
  Product owners should use realistic prototypes repeatedly and over an extended period. Daily use reveals frustrations that may not appear during a short test, including inconvenient controls, awkward storage, confusing routines, unnecessary delays, or features that become irritating over time.
  Other representative users should also live with the product because the product owner may be biased by their knowledge of the design.
• 00:27:35 – Test realistic prototypes as early as possible
  Early prototypes do not always need to contain every final feature.
  A prototype may be created specifically to test weight, grip, controls, setup, packaging, or another important aspect of the experience.
  The earlier these questions are tested, the more freedom the development team has to improve the design before tooling and production make changes expensive.

The Main Lesson

Technical specifications are essential, but they cannot fully define whether a product will be comfortable, intuitive, reassuring, or enjoyable to use.

A product may perform exactly as designed while still appearing faulty because its response is too slow, its feedback is unclear, its packaging activates it accidentally, or its controls do not behave as users expect.

It may also comply with safety limits while still feeling uncomfortable, or provide strong technical performance while being too heavy, slippery, difficult to set up, or inconvenient for its intended users.

These problems are difficult to identify using engineering reviews and checklists alone. Product owners and engineers already know how the product works and may unconsciously compensate for confusing behavior.

You should therefore test realistic prototypes with independent, representative users (or live with them themselves) as early as possible. They should observe users without providing unnecessary instructions and examine response timing, feedback, controls, labeling, setup, materials, weight, accessibility, and prolonged daily use.

The goal is not simply to prove that the product works.

Product teams need to feel it, use it, and live with it before approving it for production.

The post Why Technically Correct Products Still Fail Users appeared first on QualityInspection.org.

The first step is to determine whether the failure comes from the product design, the materials and components, or the manufacturing process itself. Buyers also need to distinguish between understandable issues during early production and repeated mistakes that reveal a supplier has weak controls, poor documentation, or no effective quality system.

In this episode of China Manufacturing Decoded, Adrian and Renaud explain how to investigate recurring production problems, what evidence a supplier should provide after claiming an issue has been fixed, and when transferring production may be the safest option.

Episode Summary

• 00:00:59 – What to do when production problems keep appearing
  A listener asks how companies should respond when manufacturing has already started, but each shipment continues to reveal new quality problems.
• 00:02:14 – Is it a design problem or a manufacturing problem?
  The first step is to identify where the failure originates. Products that cannot withstand normal use may have design or component-selection problems, while units that arrive damaged or dead on arrival are more likely to indicate workmanship or manufacturing failures.
• 00:04:40 – Validate new products before scaling production
  Innovative products should be tested with representative users before a large launch. Reliability testing can simulate expected use, but real-world pilot batches may reveal behaviours, environments, and failure modes that the development team did not anticipate.
• 00:07:00 – Why problems appear during early production
  Issues during the first production runs may indicate that the product did not undergo sufficient pilot builds, troubleshooting, verification, or process qualification before mass production began.
• 00:08:29 – When repeated factory mistakes become a serious warning sign
  Occasional production problems can happen. However, repeated basic mistakes after a product has been manufactured for some time suggest that the supplier lacks effective systems, checks, and controls. A capable factory should detect material, component, machine-setting, and workmanship problems close to their source before they reach the finished product or the customer.
• 00:10:15 – Can supplier audits reduce this risk?
  A quality system audit or initial factory evaluation can reveal whether a potential manufacturer has basic controls, records, and processes in place.
  Buyers must also understand what type of supplier they are working with. Some manufacturers can manage product industrialization and production ramp-up, while others expect the customer to provide detailed technical and project management guidance.
• 00:12:38 – What evidence proves that a problem has been fixed?
  A supplier’s promise that “it will be better next time” is not enough.
  The supplier should investigate the problem, identify its root cause, contain any affected materials or products, implement corrective actions, and validate that the solution works without creating unintended consequences.
• 00:15:38 – Using fixtures to improve consistency
  If a manual operation is producing inconsistent results, a fixture or jig may make the task easier and more repeatable.
  The supplier should provide evidence that the fixture exists, demonstrate how it is used, update the relevant work instructions, and confirm that the new process has been validated.
• 00:16:13 – Make processes easier, better, faster, and cheaper
  Process improvements should first make the task easier for the operator. Easier operations are usually performed more consistently, often become faster, and may ultimately reduce labour and quality costs.
• 00:19:09 – Corrective action versus more inspections
  Some inspection is necessary because defects must be detected before corrective action can begin. Additional inspections may also be needed temporarily when a serious problem appears.
  However, buyers often focus on inspecting finished products without investing enough effort in improving the process that created the defects.
• 00:21:37 – When inspections become supplier babysitting
  If inspectors check everything indefinitely, the manufacturer may begin relying on the buyer’s inspection team to determine whether production is acceptable.
  This removes responsibility from the supplier and discourages them from developing their own effective quality system.
• 00:22:02 – Containment and corrective action must run together
  Extra inspections can act as a temporary filter while the supplier investigates and removes the root cause.
  The buyer may manage the inspection and containment side, while the supplier works on the corrective action. Both activities should continue until there is reasonable evidence that the problem will not return.
• 00:23:12 – Common factory weaknesses to investigate
  Recurring problems often come back to a relatively short list of weaknesses:
  1. Poor incoming material and component controls
  2. No formal first-article approval
  3. Inadequate checks during production
  4. Unclear work instructions
  5. Poor understanding of likely defects and critical characteristics
  6. Insufficient mistake-proofing
  7. Inadequate use of fixtures, jigs, and tooling
  Blaming an individual operator is not a root-cause analysis. The real question is why an untrained or unsupervised operator was allowed to perform an uncontrolled process on the product.

The Main Lesson

Production problems do not automatically mean that a supplier is incapable. New products and early production runs can reveal issues that were not identified during development or pilot manufacturing.

The critical distinction is how the supplier responds.

A capable manufacturer should be able to detect problems close to their source, produce inspection and process records, investigate root causes, implement corrective actions, update working documents, and demonstrate that the solution has been validated.

More inspections may reduce the immediate risk of defective products reaching customers, but inspection alone does not improve the manufacturing process. Used for too long, it can encourage the supplier to depend on the buyer to manage quality for them.

Buyers should therefore use inspection for short-term containment while ensuring that the supplier works on permanent process improvement. If repeated basic mistakes continue, records are unavailable, production is moved between facilities without approval, or the supplier cannot demonstrate effective corrective action, transferring production may be the safest option.

Then the team assembles everything inside the final enclosure, switches the product on, and discovers problems that did not exist before.

This is a common but often underestimated stage of new product development. Once separate components and subsystems are brought together, they create a new operating environment. Heat accumulates, airflow is restricted, electromagnetic interference may appear, mechanical clearances tighten, and access to important test points can disappear.

In this episode of China Manufacturing Decoded, Adrian and Paul Adams examine why apparently successful components can fail when integrated into a complete product. They also explain how staged integration, early testing, accessible debugging points, and realistic user testing can prevent these problems from derailing a project.

Episode Summary

• 00:00:21 – Why individually working parts can fail together
  Electronics, firmware, power systems, wiring, mechanical parts, and the enclosure may all work independently. Combining them creates new interactions and operating conditions.
• 00:02:28 – Why everything seems to work on the test bench
  Bench testing gives engineers plenty of space, controlled power, monitoring equipment, test probes, and easy access to the product’s electronics.
• 00:07:40 – What changes when product integration begins
  Integrating systems too early, before each one has been properly validated, can make it extremely difficult to determine which subsystem is causing a fault.
• 00:08:39 – Products must be designed so engineers can debug them
  PCBs need accessible test points and connections that allow engineers to monitor signals, update firmware, and investigate faults after components have been installed.
• 00:10:16 – Integrate one subsystem at a time
  Adding several PCBs, sensors, motors, or other systems simultaneously makes troubleshooting unnecessarily difficult. A staged build allows the team to identify exactly when a problem appears.
• 00:13:45 – A technically compliant product can still fail
  A product may meet its written specification and applicable safety limits but still provide a poor or even alarming user experience.
• 00:15:00 – How heat buildup creates hidden product problems
  A kitchen appliance discussed in the episode remained within its assumed technical limits, but its surface became too hot for users to handle comfortably. This illustrates why regulatory or specification compliance should not be treated as the only measure of success.
• 00:20:19 – The first assembled product is only a mini milestone
  Building the first complete, functioning unit is an important achievement. However, it should be treated as the beginning of integrated system testing rather than proof that the design is finished.
• 00:21:39 – Solving an enclosure airflow problem
  Paul describes a recent project where heat had nowhere to escape from the enclosure. Adding an airflow path and a very small fan reduced the temperature substantially. This issue would not have appeared while the heating subsystem was being tested by itself on the bench.
• 00:23:53 – A five-step product integration playbook
  Paul concludes with five practical rules for managing integration:
  1. Integrate the product in stages.
  2. Test important risks early.
  3. Keep debugging access available.
  4. Test the product as customers will actually use it.
  5. Treat the enclosure as an active part of the complete system.

The Main Lesson

Testing components separately is essential, but it does not prove that the finished product will work correctly.

The enclosure affects airflow, temperature, signal behaviour, component positioning, accessibility, and the way users interact with the product. It should therefore be considered part of the system rather than simply a cosmetic shell added at the end.

Teams should also avoid treating the first complete build as a finished product. It is the first opportunity to observe how all of the subsystems interact under realistic conditions.

Problems found at this stage may still require changes to the electronics, firmware, component selection, internal layout, materials, ventilation, or enclosure design. Discovering and correcting those issues before tooling and production is far less damaging than finding them after products reach customers.

The real value of events such as the Canton Fair and Global Sources comes from knowing what to ask, what to observe, and which suppliers deserve further investigation.

In this episode of China Manufacturing Decoded, Adrian and Renaud explain how buyers can assess suppliers during an initial booth conversation. They cover how to identify possible trading companies, ask about in-house processes, judge production capacity and customer fit, and avoid being treated as an unprepared “tire kicker.”

They also explain why trade show conversations should only be the beginning of the qualification process. Promising suppliers still need background checks, factory visits, and proper due diligence before you place an order.

Listen to the audio here or on Apple Podcasts · Spotify · Amazon Podcasts · Deezer · iHeartRADIO · TuneIn.

Episode Summary

Trade shows remain valuable because they allow buyers to examine physical products, compare many potential suppliers quickly, and ask questions in real time. They are also useful for spotting market trends and emerging technologies. However, products displayed widely at events such as the Canton Fair may also be easily accessible to competitors, so buyers should look for opportunities to differentiate rather than copy what everyone else can see.

Preparation is essential. Buyers should research exhibitors beforehand, arrive with a clear description of what they need, and ask suppliers about their main products, factory location, in-house processes, target markets, customer types, and production capacity. These questions can help reveal whether the exhibitor is a genuine manufacturer or a trading company, whether it controls critical production processes, and whether its size and capabilities are suitable for the buyer’s expected volumes.

Suppliers are also assessing visitors. To avoid being dismissed as a “tire kicker,” buyers should explain their company, market experience, product maturity, and realistic sales forecasts. Exaggerated promises about huge future orders are unlikely to be taken seriously. It is better to discuss credible volumes across the first few years and explain how a smaller initial order could lead to larger business later.

Finally, a professional booth and attractive samples do not prove that a supplier is reliable. Promising conversations should be followed by background checks, factory visits, and more detailed discussions with technical and operational staff before any order is placed.

But by that stage, the products have already been made.

If a large part of the batch has the same problem, inspection can identify the failure, but it cannot undo the time, materials, and production capacity already spent.

A stronger approach is to define how quality will be controlled before production begins.

Here we’ll explain three types of quality control plans:

1. A product quality control plan that defines inspection, testing, acceptance criteria, responsibilities, and what happens when products fail.

2. A process control plan that identifies critical production steps and explains how quality will be checked while the products are being made.

3. A QC plan for a new product that addresses additional risks involving approved samples, test fixtures, components, tooling, pilot runs, reliability, and compliance.

The discussion also explains why buyers need to define their own quality standards rather than assuming the supplier will do it for them.

Some are worried about tariffs. Others want to reduce China-related risks, move closer to their customers, protect their IP, or stop relying on a single supplier that has too much control over their production.

So the idea comes up: should we move production to a new factory?

Maybe Vietnam looks attractive. Maybe Mexico seems closer to the US market. Maybe another supplier in China can do the job. Or maybe the company decides it should own the manufacturing process itself.

But a factory move is not automatically an improvement.

If the current production setup has a poor layout, weak process controls, too much inventory, unreliable equipment, or a poorly understood supply chain, moving to a new building may simply copy those same problems into a different location.

That was one of the main points made by David Collins, CEO of Manufacturing Transformation Group, in a recent discussion with Renaud Anjoran on the China Manufacturing Decoded podcast.

Before choosing a country, a supplier, or a building, companies need to ask a more basic question:

What problem are we really trying to solve?
