- Requirements to specsThe customer says sturdy and cheap, which is not a spec.
- Material selectionOne says carbon steel, another says stainless.
- Drive train comparisonMotor with screw, or a cylinder? Unclear.
- Structural checkWill this bracket hold or bend?
- Tolerances and fitsParts do not assemble, or they assemble loose.
- Motor sizingPicking a motor by wattage and it stalls.
- Bearing life estimateBearings keep failing; sizing or mounting is unclear.
- Sealing designThis joint keeps leaking.
- Thermal designIt throttles when hot and sometimes burns.
- Harness and connectorsThe harness is a mess and connectors keep losing contact.
- Schematic reviewThe schematic is about to be released and I fear errors.
- Control sequenceThe sequence is vague and things crash during commissioning.
- Sensor selectionSensors false-trigger or miss entirely.
- DFMEADesign review consists of everyone saying it should be fine.
- Drawing annotationThe shop calls twenty times about the drawing.
- Assembly sequence and poka-yokeParts get reversed or left out.
- Lightweighting trade-offsWeight must come down without losing strength.
- Cost versus processQuotes differ threefold and I cannot see why.
- Prototype test planThe prototype exists and nobody defined pass.
- Failure analysisIt broke or burned and the supplier blames usage.
- Standards and certificationExporting and unsure which certifications apply.
- Supplier technical reviewThe supplier said they could and could not.
- ECN assessmentOne dimension change that seems trivial.
- On-site troubleshootingThe machine is down at the customer and I am guessing by phone.
- Routing designA new part needs a route and the sequence is undecided.
- Standard work instructionA ten-page SOP nobody reads; they work by feel.
- Control planCritical dimensions rely on 100 percent final inspection.
- Inspection and samplingQC passes it, the customer rejects it, standards differ.
- Fixture requirementsOperators tap parts into place and position varies every time.
- Capacity and taktThe order arrives and capacity is not there.
- Line balancingSome stations are overwhelmed, others idle.
- Changeover reductionA model change stops the line for two hours.
- Defect analysisFive percent defects and everyone is guessing.
- First-off inspectionNo first-off check, then a whole batch is scrap.
- Nonconforming materialDefective parts pile up on the line.
- TraceabilityA customer complains and the build date is unknown.
- Equipment checks and maintenanceMachines are fixed after failure, and the line stops.
- Improving OEEOEE sits at 55 percent and priorities are unclear.
- Layout and 5SThe shop is chaos and finding a tool takes ten minutes.
- Safety hazard reviewHazards get reviewed only after a near miss.
- Incoming inspectionIncoming quality swings and the line keeps swapping material.
- Rework planRework depends on one veteran's feel and still fails.
- Packaging and transportGoods arrive scratched and deformed.
- Pilot to mass productionPilot passed and mass production fails.
- Labour standards and piece ratesPiece rates are skewed: speed over quality or people leave.
- Energy and material lossEnergy and scrap keep eating margin.
- Automation assessmentAutomation is tempting and payback is unclear.
- Tracing a complaint backA complaint arrives and the process cause is unknown.
