# Observation–Inference Ledger — completed example

Source: https://richbay.ai/cases/pilot-evidence-boundary
This is an editorial teaching example based on the published task packet, not a new model run or customer result.

## Decision
- Decision: expand, pause, or stop the pilot?
- Decision owner: the pilot owner in this exercise.

## Ledger
| Observation | Source | Proposed inference | Missing basis | Supported? |
| --- | --- | --- | --- | --- |
| 48 invited users; 18 weekly active | Task packet | Engagement is low | Agreed target or relevant comparison | Unresolved |
| 7 interviews; 5 request CSV export | Task packet | All users need CSV export | Representative evidence beyond interviewees | No |
| Pilot has run for 3 weeks | Task packet | Users will continue using it | Longer-term retention observations | Unresolved |

## Bounded conclusion
- Supported: some interviewed users requested CSV export; weekly activity was observed.
- Not established: representative demand, durable retention, or readiness for broad expansion.
- Proposed action: pause expansion while continuing a bounded evidence-gathering pilot. This is a recommendation, not an observed event.
- Reason: current evidence cannot establish readiness to expand; it also does not establish failure.

## Next evidence
- Record repeat use by cohort and interview active and inactive participants.
- Before collecting results, agree on a success threshold, review date, and usage cadence with the pilot owner. The packet does not justify a fixed number of weeks.
- Reconsider expansion if the agreed criteria are met; revise or stop if repeated observations show the intended use is not happening.

Inside a reviewed case

Three correct answers.
Different paths to trust.

All three captured outputs reach the same budget total. Compare how easily you can verify the steps.
