Freeze the lot sample and decision rule
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. Fictional Hazel card lot L8 has 100 units. Authorized exercise plan: preselected random sample IDs04,12,19,27,38,43,56,61,77,92; n=10; accept if at most 1 nonconforming unit; reject/hold if2+. This classroom plan is not a validated safety sampling scheme.
A sample disposition is meaningful only when the lot identity, selection method, sample size and acceptance rule were set before seeing results.
Freeze the lot sample and decision rule — worked practice
A sample disposition is meaningful only when the lot identity, selection method, sample size and acceptance rule were set before seeing results.
Fictional Hazel card lot L8 has 100 units. Authorized exercise plan: preselected random sample IDs04,12,19,27,38,43,56,61,77,92; n=10; accept if at most 1 nonconforming unit; reject/hold if2+. This classroom plan is not a validated safety sampling scheme. Use paper or a local document. Preserve the original case and make a separate changed-case record.
1. Step 1
Record L8 population 100 and exact ten sample IDs.
You should see: One fixed lot and ten distinct preselected units.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
2. Step 2
Write acceptance number before classifying measurements.
You should see: c=1; 2+ nonconforming units triggers hold/reject.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
3. Step 3
Keep sample selection independent of convenient appearance.
You should see: Do not replace a selected damaged unit with a better-looking unit.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
4. Step 4
Save the locked inspection-plan cover sheet.
You should see: L8, n10, c1, selection IDs and disposition authority recorded before results.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
What to finish
Save the locked inspection-plan cover sheet; include the original-case decision evidence and a separate changed-case result.
Watch for this
Choosing a passing sample or changing the threshold after seeing the measurements.
How can I tell I understand it?
Using the supplied identifiers, I can save the locked inspection-plan cover sheet. My changed-case record names the revised condition and explains which dependent decision it changes.
