Calculate demand pace with usable 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. Willow has 240 scheduled minutes, 30 minutes excluded breaks, and demand for 140 paper units. Usable time 210 min=12,600 sec. The demand/time are fictional; no performance target is imposed on real workers.
Takt time is available production time divided by demand for that same period; breaks and units must be handled consistently.
Calculate demand pace with usable time — worked practice
Takt time is available production time divided by demand for that same period; breaks and units must be handled consistently.
Willow has 240 scheduled minutes, 30 minutes excluded breaks, and demand for 140 paper units. Usable time 210 min=12,600 sec. The demand/time are fictional; no performance target is imposed on real workers. Use paper or a local document. Preserve the original case and make a separate changed-case record.
1. Step 1
Subtract excluded breaks from scheduled time.
You should see: 240−30=210 usable minutes.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
2. Step 2
Convert usable minutes to seconds.
You should see: 210×60=12,600 seconds.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
3. Step 3
Divide by period demand.
You should see: 12,600÷140=90 sec per demanded unit.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
4. Step 4
Save the takt calculation with period and exclusions.
You should see: A demand-pace record:90 sec/unit for this 210-minute fictional period.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
What to finish
Save the takt calculation with period and exclusions; include the original-case decision evidence and a separate changed-case result.
Watch for this
Mixing minutes and seconds or describing required demand pace as proven capacity.
How can I tell I understand it?
Using the supplied identifiers, I can save the takt calculation with period and exclusions. My changed-case record names the revised condition and explains which dependent decision it changes.
