You: We have six leak complaints. Are they recurring on one lot?

neil

There are six reports, but two refer to the same returned unit. One lot also lacks its distribution denominator. I would preserve all reports while resolving physical-unit identity and lot exposure before comparing recurrence rates.

You: So should we change the count to five?

neil

Only for a defined, verified unique-unit analysis—not by deleting a complaint. The known duplicate pair does not establish that every other report is a distinct unit. I would group linked reports, resolve remaining identities and retain both report counts and confirmed unit counts.

You: Write this up for review, with the sources and the follow-up work we need.

Here is the draft. I have kept the supported finding separate from the open questions, and prepared the evidence requests for the responsible roles.

Leak complaint identity and recurrence assessmentReview draft · source evidence and assessment

Leak complaint identity and recurrence assessment

Two reports refer to one returned unit, so report count and independent-unit count are different measures. Resolve the other report identities before establishing a failure numerator, then obtain lot-specific distribution quantities for the denominator. Preserve the original six reports and their links; deduplication should explain the analytical grouping, not delete the source complaints.

CMP-303 / New reports

Recorded evidence
Six reports describe a leaking closure

DUP-303 / Case linkage

Recorded evidence
Two reports concern the same returned unit

DIST-303 / Distribution data

Lot-specific quantities missing for one reported lot
Inputs needed for your own records
  • Complaint narratives, product identities and reported lots
  • Duplicate-case links and distribution quantities
  • Batch, deviation and packaging-change evidence

Complaint and quality owners assess significance and applicable reporting obligations. Text similarity alone does not establish a common defect.
