Count bad units separately from individual defects

About 10 minutes · 3 reading + 7 practice and checks
Time includes reading, practice, and questions. Extra videos or further study are optional.
See this course’s project requirements

A fictional quality-inspection record with sample selection, boundary classifications, stated acceptance-rule application and a traceable release-or-hold memo.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Save the locked inspection-plan cover sheet; include the original-case decision evidence and a separate changed-case result.
  • Save an item-level inspection sheet with criterion reasons; include the original-case decision evidence and a separate changed-case result.
  • Save a two-measure summary and apply the unit-count gate; include the original-case decision evidence and a separate changed-case result.
  • Write a bounded conclusion without whole-lot guarantee; include the original-case decision evidence and a separate changed-case result.
  • Save the disposition trail and remaining signoff hold; include the original-case decision evidence and a separate changed-case result.
  • Save two-lot inspection/disposition packet and improvement; include the original-case decision evidence and a separate changed-case result.

Review and revise

Use these criteria to check your work and choose what to improve.

  • The final packet uses the supplied task-specific constraints and all six records agree.
  • Every result can be traced to an identifier, input, calculation or stated decision rule.
  • Changed-case practice updates dependent records and keeps holds or uncertainty visible.
  • The packet states the learner role, authority boundary and specific next verification needed before real work.

The idea in everyday life

Original fictional workplace practice; paper or a local document is sufficient. The rules and records below are supplied for this exercise, not asserted universal workplace policy. Hazel revised observation:19 has width 51.2 and wrong label; 27 width 50.0 and wrong label. The other eight meet both criteria. Exercise acceptance still counts nonconforming units, not total defect findings.

The idea

The specified count may concern units rather than defects; several failures on one unit do not necessarily increase the number of nonconforming units.

Count bad units separately from individual defects — worked practice

The specified count may concern units rather than defects; several failures on one unit do not necessarily increase the number of nonconforming units.

Hazel revised observation:19 has width 51.2 and wrong label; 27 width 50.0 and wrong label. The other eight meet both criteria. Exercise acceptance still counts nonconforming units, not total defect findings. Use paper or a local document. Preserve the original case and make a separate changed-case record.

  1. 1. Step 1

    List findings with unit IDs and criteria.

    You should see: 19 has two findings; 27 has one.

    Keep the stated identifier, unit and policy alongside this result so another reader can check it.

  2. 2. Step 2

    Count distinct units with any finding.

    You should see: Two nonconforming units.

    Keep the stated identifier, unit and policy alongside this result so another reader can check it.

  3. 3. Step 3

    Count defect findings separately for diagnosis.

    You should see: Three findings:one width and two labels.

    Keep the stated identifier, unit and policy alongside this result so another reader can check it.

  4. 4. Step 4

    Save a two-measure summary and apply the unit-count gate.

    You should see: Nonconforming units 2→hold; three findings retained as separate detail.

    Keep the stated identifier, unit and policy alongside this result so another reader can check it.

Now change one thing

A third label finding occurs on already-failing 19. How many nonconforming units remain?

Your work

What to finish

Save a two-measure summary and apply the unit-count gate; include the original-case decision evidence and a separate changed-case result.

Common mistake

Watch for this

Applying a defect count to a rule defined for nonconforming-unit count.

How can I tell I understand it?

Using the supplied identifiers, I can save a two-measure summary and apply the unit-count gate. My changed-case record names the revised condition and explains which dependent decision it changes.
