Find the real capacity limit
See this course’s project requirements
A two-product costing and constrained-capacity model with contribution, overhead, bottleneck minutes and a demand-limited production recommendation.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- A cost-classification and unit-cost schedule.
- A contribution schedule and two-product profit bridge.
- An overhead-rate and applied-versus-actual reconciliation.
- A capacity feasibility and contribution-per-minute table.
- A checked feasible product mix with an explicit tie and resource ledger.
- A price/capacity sensitivity and conditional product-mix recommendation.
Review and revise
Use these criteria to check your work and choose what to improve.
- Costs: behavior, units and overhead assignment are explicit.
- Feasibility: time/demand/whole-unit constraints hold.
- Objective: contribution and fixed-pool profit reconcile.
- Decision: ties and changed-price/capacity scenarios are checked.

The idea in everyday life
Original fictional practice. All money is USD. No account, payment, personal record or outside participation is required. Fictional workshop sells whole units only. Product A: price 30, variable material 12, variable labor 6, bottleneck 6 min, demand cap 50. Product B: price 24, material 8, labor 4, bottleneck 4 min, demand cap 80. Available bottleneck time 600 min. Monthly fixed manufacturing overhead 600, budget activity 600 min (rate 1/min). All produced units sell within demand limits; no inventory, other constraints or taxes in this bounded model.
The scarce resource is a common denominator for competing products.

Two products
Paste at A1.
| AProduct | BPrice | CMaterial | DVariable labor | EMachine min | FMax demand |
|---|---|---|---|---|---|
| A | 30 | 12 | 6 | 6 | 50 |
| B | 24 | 8 | 4 | 4 | 80 |
Copy as plain text
1. 4.1 Find
Compute contribution divided by bottleneck minutes for both products.
You should see: A2/min; B3/min.
2. 4.2 Find
Test the proposed maximum-demand mix against 600 minutes.
You should see: 620 minutes exceeds available time by 20.
3. 4.3 Find
Identify B as initial priority while retaining its 80-unit demand cap.
You should see: Priority is not permission to make 150 B units for sale.
4. 4.4 Find
Check a changed A cycle of 3 minutes: A contribution/min 4 now exceeds B3.
You should see: The prioritization changes with the resource coefficient.
What to finish
A capacity feasibility and contribution-per-minute table.
Watch for this
Choosing on unit contribution alone or manufacturing units beyond sellable demand.
How can I tell I understand it?
Verify that your completed capacity feasibility and contribution-per-minute table meets the three lesson-specific checks and retains the supporting original records.
