Before Expanding a Plan, Name the Evidence You Need

A plan can begin to expand before leaders know whether its most important assumptions are sound. Early enthusiasm may lead to a larger budget, more staff or a second location, even when the original approach has not produced enough information to guide that decision.

A short evidence check helps leaders separate momentum from proof. It does not require complicated research. It requires agreement about what must be true, what will be observed and what decision the evidence will support.

Use Assumption–Evidence–Decision

Before approving an expansion, write three lines.

Assumption: Name the condition that must be true for expansion to make sense. Keep it specific. “People like the program” is too broad. “Current sessions show enough consistent demand to support another location” is clearer.

Evidence: Decide what information would support or challenge the assumption. Choose a review period and observable signals before looking at the results. These might include registrations, attendance, repeat participation, delivery capacity, costs or staff workload. Select measures that fit the decision instead of collecting information without a purpose.

Decision: State what you will do under different results. For example: expand with a small pilot, adjust the current model and test again, or pause the expansion. Naming the options in advance makes it easier to respond honestly when the evidence is mixed.

The routine does not eliminate judgment. It gives leaders a clearer basis for using it.

A hypothetical workplace example

Imagine an organization is considering a second location for a monthly business workshop. In this hypothetical example, the team identifies one assumption: the current workshop has enough continuing demand and facilitator capacity to support a second site.

For four weeks, the team reviews registrations, actual attendance, waiting-list requests and facilitator workload. Before the review begins, leaders agree that strong demand and manageable workload would support one limited pilot at the new location. If demand is inconsistent or the current team is already stretched, they will improve the existing workshop before expanding.

The team is not trying to prove the idea is good. It is gathering the information needed to choose the next responsible step.

Take one plan that may grow soon and complete these sentences:

Assumption: This expansion makes sense only if…

Evidence: We will review these signals by…

Decision: Based on the result, we will expand, adjust or pause by…

Share the three lines with the people responsible for delivery so everyone knows how the decision will be made.
