Reduce the work required to correct product after the first pass.
Rework consumes machine time, labor, inspection capacity, material handling, and schedule space without increasing finished output. Reducing it requires identifying the process conditions that create repeat repairs, retests, and repeated handling.
Track the losses that consume capacity without creating good output.
Rework, defects, process variation, inspection, scrap, and yield should be tied back to the production conditions that created them.
Move from detection toward prevention.
Inspection is necessary, but the larger gain comes from making the process stable enough that fewer defects are created in the first place.
CRIT-ATrack Repeat Repairs
A defect that repeatedly sends product through the same repair path deserves separate visibility from one-time correction.

Rework at the bottleneck consumes scarce capacity that could otherwise produce new good output.

Inspection results should reach the responsible process quickly enough to prevent more units from entering the same defect condition.

These diagrams separate recurring quality loss from overall process stability and improvement trend.

Track recurring quality loss over time to see whether changes are reducing the problem.
Process stability.
Stable process behavior supports better yield and fewer quality escapes.
