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: Inventory and Order Operations. 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 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  • Save the v2 shortage with EC2 link and superseded v1 value; include the original-case decision evidence and a separate changed-case result.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.
Three ideas to help you along the way
Three useful ideas

The rules behind the steps.

01

Match the task-specific constraint

A bill of materials is a hierarchy: quantities belong to one parent, so a component reached through two branches contributes through both.

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 material plan is not a release: authorization, current revision and dated shortages must all be resolved under the supplied gates.

What do these words mean?
Key words

Key terms worth knowing.

BOM edge
A component quantity per one immediate parent.
Gross requirement
Demand before usable supply is netted at the relevant level.
Net requirement
The unsatisfied quantity after eligible dated supply.
Lead-time offset
Backward scheduling from a dependent required date.
Engineering change
An approved revision to the defined product relationships.

6 lessons.
One useful project.

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

  1. 1
    Up next

    Read parent-child quantities and revision levels

    Save a v1 gross-material explosion grouped by component. Explain how a bill of materials is a hierarchy: quantities belong to one parent, so a component reached through two branches contributes through both.

  2. 2
    15 min

    Net finished and intermediate stock in dependency order

    Net loose stock and save the dependency calculation. Explain how netting must occur at the level where usable stock exists; stocked assemblies already contain their components and should not be exploded again.

  3. 3
    13 min

    Separate usable receipts reservations and holds

    Write a Day3 shortage register with excluded supply reasons. Explain how availability is specific to this order and its required date; a held item or receipt arriving later cannot support an on-time release.

  4. 4
    13 min

    Offset lead times from the required assembly date

    Save the dated dependency schedule and late-order flag. Explain how backward scheduling subtracts supplied lead times along dependencies; it does not make a late receipt timely merely by changing a calendar label.

  5. 5
    15 min

    Reconcile an approved engineering change

    Save the v2 shortage with EC2 link and superseded v1 value. Explain how a revision changes only its stated relationships, but every dependent quantity must be recalculated from the approved version.

  6. 6
    17 min

    Make a material-ready release decision

    Assemble the versioned manufacturing-planning packet. Explain how a material plan is not a release: authorization, current revision and dated shortages must all be resolved under the supplied gates.
