Working sequence

  1. Set the purpose, evidence boundary, accountable owner, and review cadence.
  2. Complete the fields from current evidence and make assumptions explicit.
  3. Use the result to support a review conversation, not as an automatic decision.
  4. Record the resulting action, decision, or next review date with the appropriate owner.

Inputs and method

Complete the fields below with evidence suitable for review. The tool structures the work; professional judgement remains necessary.

  • Annual net benefit
  • Analysis years
  • Discount rate (%)

Fictional learning scenario: Use the labelled fictional example in the online tool as a learning starter; replace it with authorised local evidence.

Review and decision prompt

Does the investment remain attractive under transparent assumptions and plausible downside scenarios?

Common failure mode

Financial outputs mislead when timing, taxes, risk, alternatives, or non-financial effects are silently excluded.
