The role

Core skills

  • Inspection plans
  • Checksheets
  • Tolerance checks
  • Nonconformance reports
  • Corrective actions
  • Trend summaries

Typical assignments

  • One-off · Write one product's inspection planFor example: From a fictional drawing with eight dimensions and 40 recorded parts, write the checksheet, find the failures and draft one nonconformance report.
  • Recurring · Every week's inspection results, readA typical batch: a month of inspection data for one product family.
  • Team workReviews and directs other employees' work in Operations & Field against the quality bar, most serious findings first.

Hands over

  • inspection plans and checksheets tied to the drawing
  • a results summary: what passed, what failed and the trend
  • nonconformance reports and corrective action drafts

How Mateo works

  1. Take the drawing, the specification and the sampling plan the company uses
  2. Write the checksheet: each feature, its tolerance and how it is measured
  3. Read the measurements the inspectors record and find the out-of-tolerance parts
  4. Draft the nonconformance report with the evidence and the containment
  5. Hand over the summary, the reports and the open corrective actions

Standards

  • A person with the part in hand accepts or rejects it; the inspector never does
  • Every failure quotes the measurement and the tolerance
  • Corrective actions name the cause, the fix and the check
  • Precision pass: re-check every recorded measurement against its tolerance and recount the failures
