# Add a shared-resource constraint to a schedule

Illustrative planning brief; no automatic product import.

Synthetic planning case: Two independent artwork tasks take three and four model days. Both require the same sole illustrator full-time; final assembly takes one day after both.

## Decision

The resource-constrained plan needs at least eight model days: seven illustrator-days in sequence, then one assembly day. Logical independence does not create a second illustrator.

## Owned work

- Check exclusive resource use
  - Owner role: Resource owner
  - Acceptance evidence: A and B cannot use the sole illustrator simultaneously under this model.
- Revise the feasible sequence
  - Owner role: Scheduler
  - Acceptance evidence: The illustrator has seven nonoverlapping model days before assembly.
- Explain the schedule change
  - Owner role: Project lead
  - Acceptance evidence: Five is labelled a network-only result; eight reflects the declared resource constraint.

## Workflow

1. Check exclusive resource use. Check: A and B cannot use the sole illustrator simultaneously under this model.
2. Revise the feasible sequence. Check: The illustrator has seven nonoverlapping model days before assembly.
3. Explain the schedule change. Check: Five is labelled a network-only result; eight reflects the declared resource constraint.

## Judgment

This simple exclusive-resource case is not a general resource-optimization solver. Durations and availability remain assumptions.


## Filled manual planning note

The resource-constrained plan needs at least eight model days: seven illustrator-days in sequence, then one assembly day. Logical independence does not create a second illustrator. Without contention the network-only finish would be max(3,4)+1=5. The stated exclusive resource requires 3+4+1=8 days. This simple exclusive-resource case is not a general resource-optimization solver. Durations and availability remain assumptions.


## Before / after

Before: Network-only plan: five model days with unlimited independent artwork resources.

After: Declared sole-illustrator plan: eight model days with artwork serialized.


## Workflow questions

### Can I choose either artwork first?

Yes under these inputs; both orders finish at eight days. Other deadlines may distinguish them.

### Does another team member remove the constraint?

Only if their eligibility and availability are established; do not infer substitution from headcount.

## Product connection

Use the owned checks and downloaded brief to discuss this planning decision alongside your TeamBoostAI tasks. Confirm available fields, roles and account features separately. The example is manual; it does not calculate live analytics, create work or run an experiment in the product.

Confirm account availability before adopting this manual outline.

## Original worked case

Synthetic records, manual planning only. No account import or live analytics.

### Inspect the invented case records

Activity | Model duration | Required resource
--- | --- | ---
Artwork A | 3 days | Sole illustrator
Artwork B | 4 days | Same illustrator
Assembly | 1 day | Separate assembler after both

### Reasoning

Without contention the network-only finish would be max(3,4)+1=5. The stated exclusive resource requires 3+4+1=8 days.

### Bounded result

The resource-constrained plan needs at least eight model days: seven illustrator-days in sequence, then one assembly day. Logical independence does not create a second illustrator.

### Distinct decision

The example isolates the difference between logical parallelism and actual shared-resource feasibility.

### Limits

This simple exclusive-resource case is not a general resource-optimization solver. Durations and availability remain assumptions.
