# Compare matched work cases in a process pilot

Illustrative planning brief; no automatic product import.

Synthetic planning case: Four matched rehearsal tasks are timed before and after a process change. Times in minutes are A10→8,B12→12,C14→11,D16→15; repeated practice may also affect the result.

## Decision

The paired reductions are two, zero, three and one minutes, averaging 1.5. Keep the unchanged B case and the practice limitation rather than claiming every task improved because of the change.

## Owned work

- Verify paired identity
  - Owner role: Pilot recorder
  - Acceptance evidence: Each before/after row concerns the same defined rehearsal task.
- Retain case-level differences
  - Owner role: Reviewer
  - Acceptance evidence: The zero-change B row remains visible beside the other reductions.
- Investigate alternative explanations
  - Owner role: Process lead
  - Acceptance evidence: Practice, order and changing conditions are considered before attributing the result.

## Workflow

1. Verify paired identity. Check: Each before/after row concerns the same defined rehearsal task.
2. Retain case-level differences. Check: The zero-change B row remains visible beside the other reductions.
3. Investigate alternative explanations. Check: Practice, order and changing conditions are considered before attributing the result.

## Judgment

A four-case paired illustration is not a causal or statistically calibrated process evaluation.


## Filled manual planning note

The paired reductions are two, zero, three and one minutes, averaging 1.5. Keep the unchanged B case and the practice limitation rather than claiming every task improved because of the change. Total paired reduction=2+0+3+1=6 minutes over four tasks; mean reduction=1.5. Before mean 13 and after 11.5 preserve the same matched cases. A four-case paired illustration is not a causal or statistically calibrated process evaluation.


## Working artifact

- A,C,D reductions / Two,three and one minutes / Keep each matched case
- B unchanged / Twelve minutes both times / Do not claim universal improvement
- Practice unresolved / Repeated rehearsal may affect timing / Review sequence and context in the next pilot


## Workflow questions

### May I compare unmatched before/after averages instead?

That answers a different question and can mix different task composition. Preserve pairing when it is the intended design.

### Does a positive mean prove the process caused improvement?

No. These invented repeated rehearsals leave practice and other explanations unresolved.

## 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

Matched task | Before minutes | After minutes | Before minus after
--- | --- | --- | ---
A | 10 | 8 | 2
B | 12 | 12 | 0
C | 14 | 11 | 3
D | 16 | 15 | 1

### Reasoning

Total paired reduction=2+0+3+1=6 minutes over four tasks; mean reduction=1.5. Before mean 13 and after 11.5 preserve the same matched cases.

### Bounded result

The paired reductions are two, zero, three and one minutes, averaging 1.5. Keep the unchanged B case and the practice limitation rather than claiming every task improved because of the change.

### Distinct decision

The guide preserves matched differences and exceptions rather than comparing unrelated aggregate groups.

### Limits

A four-case paired illustration is not a causal or statistically calibrated process evaluation.
