Definition and context
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.
Where this term fits in the workflow
In-Process Quality Control (IPQC) is usually shown in the inspection and sampling.
Terms used when teams decide what to inspect, how much to sample, and whether a lot can ship.
What is KaizenQ?
KaizenQ helps factory teams record inspection results, defect photos, and notes in one report shared with the office.

Key takeaways
- IPQC protects production flow by detecting variation early.
- Escalation workflows prevent recurring issues from slipping through.
