Map precedence and measured task time
See this course’s project requirements
A paper assembly-station plan with precedence constraints, target cycle time, station assignments, calculated balance losses and a tested demand-change response.
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 a precedence map with five measured task durations; include the original-case decision evidence and a separate changed-case result.
- Save the takt calculation with period and exclusions; include the original-case decision evidence and a separate changed-case result.
- Save the three-station feasibility check against 90 sec; include the original-case decision evidence and a separate changed-case result.
- Save capacity estimate separately from guaranteed delivery; include the original-case decision evidence and a separate changed-case result.
- Record the rejected candidates and exact capacity reasons; include the original-case decision evidence and a separate changed-case result.
- Assemble the precedence/takt/balance/sensitivity/trial packet; 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 Willow paper assembly tasks: A mark card 30 sec; B fold 45 after A; C apply printed label 20 after A; D review 55 after B and C; E sleeve 25 after D. No tools/material handling required; times are supplied simulated observations.
A station assignment must respect task dependencies before balancing minutes; a later task cannot be moved ahead of its prerequisite.
Map precedence and measured task time — worked practice
A station assignment must respect task dependencies before balancing minutes; a later task cannot be moved ahead of its prerequisite.
Fictional Willow paper assembly tasks: A mark card 30 sec; B fold 45 after A; C apply printed label 20 after A; D review 55 after B and C; E sleeve 25 after D. No tools/material handling required; times are supplied simulated observations. Use paper or a local document. Preserve the original case and make a separate changed-case record.
1. Step 1
Draw A feeding B and C; join both into D and then E.
You should see: A→B/C→D→E.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
2. Step 2
Add the task seconds once each.
You should see: 30+45+20+55+25=175 seconds work content.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
3. Step 3
List tasks that may occur in parallel after A.
You should see: B and C have no stated dependency on each other.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
4. Step 4
Save a precedence map with five measured task durations.
You should see: A five-task map with 175 sec content; D cannot start until B and C finish.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
What to finish
Save a precedence map with five measured task durations; include the original-case decision evidence and a separate changed-case result.
Watch for this
Sorting tasks by duration while discarding their dependency constraints.
How can I tell I understand it?
Using the supplied identifiers, I can save a precedence map with five measured task durations. My changed-case record names the revised condition and explains which dependent decision it changes.
