Reduce information friction without creating a new burden

About 11 minutes · 3 reading + 8 practice and checks
Time includes reading, practice, and questions. Extra videos or further study are optional.
See this course’s project requirements

A paper task-observation study separating frequency, duration, force/posture cues and access constraints, with a low-risk process-change comparison and supervisor questions.

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 task-demand observation record and review questions; include the original-case decision evidence and a separate changed-case result.
  • Save exposure comparison without asserting safety benefit; include the original-case decision evidence and a separate changed-case result.
  • Save annotated layout proposal with fit/access review needs; include the original-case decision evidence and a separate changed-case result.
  • Save information-layout mock up and verification checklist; include the original-case decision evidence and a separate changed-case result.
  • Save small trial review with additional fit/condition questions; include the original-case decision evidence and a separate changed-case result.
  • Save ergonomic friction packet with bounded implementation brief; 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. Yew record cards:label codes P7/P8 look similar in small print; screen reflection reported; worker reads full unrelated history to find one current code. Paper options larger clear code/group current field/minimize unrelated display; actual contrast/accessibility testing not performed.

The idea

An ergonomic work-design review can include visual and information demands; proposed changes need accuracy checks as well as reduced unnecessary search.

Reduce information friction without creating a new burden — worked practice

An ergonomic work-design review can include visual and information demands; proposed changes need accuracy checks as well as reduced unnecessary search.

Yew record cards:label codes P7/P8 look similar in small print; screen reflection reported; worker reads full unrelated history to find one current code. Paper options larger clear code/group current field/minimize unrelated display; actual contrast/accessibility testing not performed. Use paper or a local document. Preserve the original case and make a separate changed-case record.

  1. 1. Step 1

    Separate three friction types.

    You should see: Similar codes/visual reflection/unnecessary information search.

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

  2. 2. Step 2

    Design clear paper labels without changing stable codes.

    You should see: Keep P7/P8IDs; add readable labels/spacing.

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

  3. 3. Step 3

    Show only task-relevant current code in the mock view.

    You should see: Original history retained controlled; not all public.

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

  4. 4. Step 4

    Save information-layout mock up and verification checklist.

    You should see: Check code accuracy, readability, privacy and actual screen conditions.

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

Now change one thing

Mock view accidentally changes P8 to P7. How many of the two code identities are now correct?

Your work

What to finish

Save information-layout mock up and verification checklist; include the original-case decision evidence and a separate changed-case result.

Common mistake

Watch for this

Solving readability by changing identifiers or claiming a paper layout has fixed actual screen conditions.

How can I tell I understand it?

Using the supplied identifiers, I can save information-layout mock up and verification checklist. My changed-case record names the revised condition and explains which dependent decision it changes.
