Monitoring and verifying quality characteristics while production is underway.
In-Process Quality Control keeps defects from snowballing by catching issues at the moment they emerge.
Operators rely on SPC charts to understand variation in real time.
IPQC checkpoints
Typical checks include torque tests, solder joint inspection, dimensional sampling, and functional verification.
Compare product results with specification limits. If using a control chart, apply its control limits and signal rules to assess process stability. Follow the reaction plan; the two kinds of limits are not interchangeable.
Coordinating responses
When readings drift, teams document containment steps and escalate to engineering for root cause analysis.
Structured root cause analysis ensures process fixes address systemic problems.
Key takeaways
- IPQC protects production flow by detecting variation early.
- Escalation workflows prevent recurring issues from slipping through.
