Summary and decision
Test the most consequential uncertainties before scaling.
Decision: Approve a pilot with explicit success, adaptation and stop criteria.
Preparation
- Bring the intervention logic and available baseline data.
- Choose a representative setting and record where it differs from other settings.
Audience
6-10 people: pilot team, intervention owner, analyst, FM, HR and sponsor delegate.

Exercises A and B
Exercise A: Experiment card
- State the mechanism and the uncertainty the pilot must resolve.
- Define who participates, duration, exposure and a feasible comparison.
- Agree measures and stop criteria before the pilot starts.
Exercise B: Learning and adaptation log
- Specify which observations would challenge the preferred explanation.
- Record implementation changes so results remain interpretable.
- Plan a review that can decide scale, adapt, repeat or stop.
Worksheets
Worksheet A
- Hypothesis and uncertainty
- Setting, participants and duration
- Baseline and comparison
- Success, adaptation and stop criteria
Worksheet B
- Observation and date
- Delivery change or external factor
- Interpretation and uncertainty
- Decision and next test
Illustrative example
Illustrative, not a real case
- Illustrative: two teams test room-release rules for four weeks.
- Compare actual room use with the same teams’ baseline and note seasonal workload.
- Treat improvement as provisional because the pilot is small and non-randomised.
Completion criteria
- The pilot can disconfirm its own hypothesis.
- Measures and decision thresholds are agreed in advance.
- The record distinguishes delivery, use and outcomes.
Follow-up
- Run the pilot and document adaptations weekly.
- Feed findings into concept confirmation before broad delivery.
Points of attention
- A before-and-after change alone does not prove causality.
- Do not scale unresolved access or workload problems.
Workplace phase and change activities
Workplace: Develop (phase in the Workplace method)
Change Management
- Prepare
Why this workshop helps: Defines a pilot with success, adaptation and stop criteria before scaling.
Adapting outside a workplace setting: Replace the room-release example with the uncertainty that matters most in your change.
- Activate
Why this workshop helps: The pilot is where new practices are first tried with support.
Adapting outside a workplace setting: Replace workplace examples with situations from your own change; the structure can stay.
- Learn
Why this workshop helps: Stop and adaptation criteria make learning explicit.
Adapting outside a workplace setting: Replace workplace examples with situations from your own change; the structure can stay.

Why here: Informs the choice for a pilot with pre-agreed measures, adaptation rules and stop criteria before scaling. It does not validate this workshop.
- Finding:
- Context, programme theory, stakeholder involvement, uncertainty and iterative refinement belong throughout intervention development.
- Limitation for workplace:
- Guidance from health research informs our design. It does not validate this workplace workshop sequence.
