An approved revenue plan does not keep its assumptions current

The annual plan was approved in September. In December, the hiring dates have moved, a partner launch is unresolved and the support team has accepted additional customer work. The spreadsheet still balances because none of its assumptions has formally failed. The business is about to spend against a version of the operating conditions that no longer exists.

Give consequential assumptions an expiry date and an event that can force earlier review. Expiry means the assumption needs a new decision before it supports further commitments. It does not mean the assumption becomes false at midnight. The purpose is to stop old approval from doing the work of current evidence.

Attach validity to the decision being supported

Start with a pending decision: authorize recruiting, commit campaign spend, reserve delivery capacity or set a regional coverage plan. Identify the few assumptions that would change that decision. A complete catalogue of every spreadsheet input is less useful than knowing which unsupported input could cause the next avoidable mistake.

A planning assumption might say that two hires will start in January, a partner will supply a defined opportunity flow or a specialist can support a new segment. Write what must be observed to keep using it. “Recruiting is progressing” cannot support a particular start date as clearly as an accepted offer and a verified start plan.

Choose the expiry from the lead time of the dependent decision. If a January start requires an accepted offer by early December under your recruiting circumstances, review before that date. A standard quarterly refresh would be too late. Conversely, stable assumptions need not be re-approved every week merely to make the process look diligent.

Use two clocks

A calendar date provides a latest review point. An event trigger catches a material change sooner. An assumption about available specialist capacity might expire before launch planning, but an unexpected customer commitment should trigger immediate retesting. Waiting for the calendar would preserve a known mismatch.

State who can assess the evidence and who can authorize the dependent decision. RevOps can maintain the connection between inputs and uses; it should not silently accept a hiring date on behalf of recruiting or reserve delivery time on behalf of the service leader. A named reviewer also needs a real question to answer.

A fictional plan reaches an expiry without a rejection

A fictional CRO plans for two sellers to start on January 11. The plan’s contribution estimate uses the company’s own ramp assumptions. Recruiting and revenue leadership agree that accepted offers by December 4 are the evidence required to keep using those starts for the next resource decision.

On December 4, one offer is accepted and the other role has no final candidate. The missing offer does not prove that the business cannot hire. It means the two-start assumption no longer has the support required for the decision that depended on it. The second contribution becomes unresolved until a revised start and ramp view is accepted.

The CRO preserves the annual target while commissioning a revised operating view. Campaign spending intended to feed both hires is now a separate choice: release the portion useful to the confirmed hire, redirect the remainder to an existing team with demonstrated capacity, or defer it. Merely moving the review date a month would continue reliance without resolving the evidence.

The recruiting owner later presents a credible February start. Leadership can replace the old assumption and evaluate its consequences. The change should identify which contribution moved and which spending decision followed. It should not rewrite September’s plan as though the February start had always been intended.

Make the interim treatment explicit

An expired assumption can be renewed with evidence, replaced with a revised input, retained as a labelled scenario or withdrawn from use. The right treatment depends on the consequence. Avoid one automatic rule that either freezes the whole business or lets every expired input continue unchanged.

Separate reversible preparation from a commitment that would be hard to recover. Preparing a revised account list may be sensible while a hiring date is uncertain. Promising coverage that requires the missing hire needs a stronger basis. State the work that may continue and the next decision that must wait.

If leadership chooses to proceed despite weak evidence, record the choice and its rationale. That is a decision to accept uncertainty, not a successful retest. Naming it allows the team to inspect the consequence later without pretending the assumption was verified.

Keep the old plan and the current operating view legible

Preserve the approved plan as the original reference. Alongside it, maintain the latest accepted assumptions and the decisions they currently support. This lets leaders distinguish a changed ambition from a changed ability to execute it. It also prevents every refresh from becoming an argument about whether the target is being lowered.

At the operating review, discuss only assumptions approaching expiry, affected by a trigger or already overdue for a consequential decision. The output should be a changed input, an explicit acceptance of uncertainty or a specific decision to pause. “Reviewed” alone is not evidence that reliance remains justified.
