4D Pilot & Rollout Planner

Plan one model-and-schedule linking trial and identify the preparation needed before rollout.

Free to useNo account neededInputs stay in your tab

Answer the starting questions, review the assumptions and explore your result. You can add more detail as you go.

What this tool covers: No construction-sequence safety approval. Person-days do not equal elapsed delivery days.

Start with what you know

Your answers stay in this tab and can carry into related tools. Use nonconfidential labels. Reloading, leaving the journey or clearing the session removes the working answers.

Choose the decision the trial should support.

Usable means the chosen package can be reviewed.

Select whether activities and dates are sufficiently defined.

Broad scopes still start with a representative package.

Choose the expected update cycle.

Explore a preliminary scenario. Methods are under review; confirm the assumptions before using a result for project decisions.

Optional refinement

3 additional fields. Open only the details you know.

Trial allocation / Are model and activity identifiers stable? (2 fields)

Optional comparison: neither allocation promises to repair an incomplete model.

Optional: test an update before scaling.

Is the change workflow agreed? (1 fields)

Optional: identify who updates links and approves versions.

Worked example

An available model and outline schedule lead to a work-breakdown action; compare five-day and eight-day trial allocations.

The example project is separate from your answers. Any visible starter rates or productivity assumptions are labeled and editable.

How this tool works

Missing model or schedule yields preparation actions. Available inputs support one linking trial. Estimate rollout only from measured comparable package and update work.

Limitations

  • No construction-sequence safety approval. Person-days do not equal elapsed delivery days.
