Here’s what you’ll need and what you’ll make. You can return to this guide during any lesson.

Who this is for

Learners ages 14+ exploring work and adults preparing for an entry-level or next-stage responsibility. Work eligibility, supervision and occupational requirements remain separate.

Prepare before lesson one
  • Paper or a local document and a basic calculator are enough; all required records are supplied.
  • Recommended preparation: Improve a Process and Check Quality. Use fictional information throughout.
Your final project

Finish with proof you can use.

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 an evidence inventory with privacy boundary; include the original-case decision evidence and a separate changed-case result.
  • Save source-linked timeline and two follow-up questions; include the original-case decision evidence and a separate changed-case result.
  • Save causal comparison with supported/unsupported claims; include the original-case decision evidence and a separate changed-case result.
  • Save condition-linked action register with physical authority boundary; include the original-case decision evidence and a separate changed-case result.
  • Save follow-up review with two exceptions and next owner; include the original-case decision evidence and a separate changed-case result.
  • Save incident-learning packet with two specific follow-ups; 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.
Three ideas to help you along the way
Three useful ideas

The rules behind the steps.

01

Match the task-specific constraint

An incident review starts from protected time-specific records; response, legal reporting and technical investigation belong to the authorized team.

02

Keep decisions traceable

Preserve the original records and identify which person or policy can authorize a change; a plausible assumption is not approval.

03

Test the handoff

A learning brief separates verified facts, provisional causes, action evidence and unanswered questions, with privacy and actual responsibility intact.

What do these words mean?
Key words

Key terms worth knowing.

Near miss
An event with potential harm without the stated injury occurring.
Evidence inventory
Source IDs, type, times and known limits.
Contributing condition
A plausible mechanism linked to evidence rather than personal fault.
Effectiveness evidence
Observed use/condition after implementation, not just an assigned action.

6 lessons.
One useful project.

Work in order the first time. Each lesson makes something the next lesson can use.

  1. 1
    Up next

    Preserve incident records without investigating physically

    Save an evidence inventory with privacy boundary. Explain how an incident review starts from protected time-specific records; response, legal reporting and technical investigation belong to the authorized team.

  2. 2
    11 min

    Build a timeline and identify unsupported links

    Save source-linked timeline and two follow-up questions. Explain how a timeline contains observed or recorded events with sources; gaps between them must remain questions rather than invented causal steps.

  3. 3
    12 min

    Compare causal hypotheses to their supporting evidence

    Save causal comparison with supported/unsupported claims. Explain how a cause claim needs a plausible mechanism and evidence; considering multiple contributing conditions is more useful than asserting personal fault from one observation.

  4. 4
    11 min

    Link corrective actions to specific contributing conditions

    Save condition-linked action register with physical authority boundary. Explain how a useful corrective action targets the verified condition, has an owner and requires implementation/effectiveness evidence; rereading a slogan does not fix a mismatched check scope.

  5. 5
    10 min

    Audit follow-up evidence and recurrence limits

    Save follow-up review with two exceptions and next owner. Explain how no recurrence in a short observation window is limited evidence; verify whether the new control was actually used and whether exposure opportunities occurred.

  6. 6
    15 min

    Write a no-blame incident-learning brief

    Save incident-learning packet with two specific follow-ups. Explain how a learning brief separates verified facts, provisional causes, action evidence and unanswered questions, with privacy and actual responsibility intact.
