Read parent-child quantities and revision levels
See this course’s project requirements
A two-level paper bill-of-materials explosion, net material requirement sheet, batch release decision and revised production packet for fictional stationery kits.
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 v1 gross-material explosion grouped by component; include the original-case decision evidence and a separate changed-case result.
- Net loose stock and save the dependency calculation; include the original-case decision evidence and a separate changed-case result.
- Write a Day3 shortage register with excluded supply reasons; include the original-case decision evidence and a separate changed-case result.
- Save the dated dependency schedule and late-order flag; include the original-case decision evidence and a separate changed-case result.
- Save the v2 shortage with EC2 link and superseded v1 value; include the original-case decision evidence and a separate changed-case result.
- Assemble the versioned manufacturing-planning 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 Spruce v1 display kit K requires 2 sub assemblies A and 1 tray T. Each A requires 3 clips C and 2 pads P. Each T requires 2 clips C. Demand is 10 K. All records are paper planning; no manufacturing is performed.
A bill of materials is a hierarchy: quantities belong to one parent, so a component reached through two branches contributes through both.
Read parent-child quantities and revision levels — worked practice
A bill of materials is a hierarchy: quantities belong to one parent, so a component reached through two branches contributes through both.
Fictional Spruce v1 display kit K requires 2 sub assemblies A and 1 tray T. Each A requires 3 clips C and 2 pads P. Each T requires 2 clips C. Demand is 10 K. All records are paper planning; no manufacturing is performed. Use paper or a local document. Preserve the original case and make a separate changed-case record.
1. Step 1
Draw K above A and T; write each quantity on its own edge.
You should see: K→2 A; K→1 T; A→3 C+2 P; T→2 C.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
2. Step 2
Multiply demand along the A branch.
You should see: 10 K require 20 A, therefore 60 C and 40 P.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
3. Step 3
Expand the T branch independently.
You should see: 10 T require another 20 C.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
4. Step 4
Save a v1 gross-material explosion grouped by component.
You should see: Gross requirements: 20 A, 10 T, 80 C, 40 P, with both clip paths visible.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
What to finish
Save a v1 gross-material explosion grouped by component; include the original-case decision evidence and a separate changed-case result.
Watch for this
Treating a per-parent quantity as a total, or losing shared components from another branch.
How can I tell I understand it?
Using the supplied identifiers, I can save a v1 gross-material explosion grouped by component. My changed-case record names the revised condition and explains which dependent decision it changes.
