A Production Readiness Exception Review focuses on the items that prevent scheduled work from being truly ready for execution.
The purpose is not to repeat the full production plan.
The purpose is to identify exceptions that can still cause delay, disruption, or schedule change before the work reaches the floor.
Start with the readiness standard
Production Readiness Review helps check whether the required material, equipment, tooling, labor, quality conditions, and information are available.
Define what “ready” means before reviewing exceptions.
Typical readiness elements include:
- material;
- tooling;
- equipment;
- labor;
- instructions;
- quality approval.
Isolate the exceptions
Do not spend equal time on work that is already ready.
List only the orders, batches, or jobs with a meaningful readiness gap.
For each exception, state:
- what is missing;
- when it is needed;
- current risk to the schedule.
Review material gaps
Plan for Every Part helps define material quantity, location, handling, and replenishment information.
Material exceptions should distinguish between:
- not received;
- not released;
- not staged;
- wrong quantity;
- wrong condition.
Review equipment and tooling gaps
Check:
- machine availability;
- changeover readiness;
- fixture condition;
- program availability.
Changeover Readiness helps move preparation outside the downtime window where practical.
Review staffing and capability
A scheduled job may have people assigned but still lack the required qualification.
Skills Matrix helps make capability coverage visible.
Readiness should reflect usable skill, not only headcount.
Decide before release
If an exception cannot be resolved in time, decide whether to:
- resequence;
- substitute work;
- escalate support;
- delay release.
Production Priority Rules helps govern tradeoffs when competing work cannot all go first.
Track recurring exceptions
Repeated readiness failures may reveal:
- supplier instability;
- weak scheduling horizon;
- planning defects;
- chronic tooling issues;
- capability gaps.
The review should reduce exceptions over time rather than normalize them.
Common mistakes
Reviewing the whole schedule instead of exceptions, defining no readiness criteria, treating material receipt as the same as material availability, ignoring qualification gaps, waiting until shift start to expose missing tooling, releasing work with known exceptions and hoping recovery will occur, and failing to analyze recurring readiness failures are common mistakes.
Practical sequence
- define readiness criteria.
- review upcoming released work.
- isolate meaningful exceptions.
- identify the missing condition.
- assign one owner.
- define the latest safe resolution time.
- escalate support where needed.
- resequence when resolution is unlikely.
- record the decision.
- analyze recurring exception patterns.
The practical lesson
A Production Readiness Exception Review protects the schedule before execution begins.
The best time to solve a readiness problem is before the order reaches the point where the plant has to stop and react.
