Brief the Decision: Show Which Assumptions Actually Drive It

For CFOs, controllers, FP&A teams, accountants and finance operations professionals

You'll produce a short decision brief that names the key assumptions, shows how sensitive the outcome is to each, and states what the evidence does and doesn't support.

In about two hours, learn to run sensitivity checks with AI's help and write a one-page brief that ranks the drivers and separates what the evidence supports from what is still open.

What you will be able to do

  • Find the inputs that matter: Trace which inputs flow into your outcome measure and shortlist the handful worth testing, instead of walking leadership through all fifty lines.
  • Run sensitivity checks you can defend: Change one input at a time over a stated low and high range, record the outcome at base, low and high, and keep a log someone else could rerun from the model.
  • Rank drivers by impact and evidence: Place each driver on an impact-by-evidence grid and say in one sentence why it ranks where it does, so leadership sees both what moves the result and how sure you are.
  • Separate facts from open questions: Record each supported fact with its source, reporting period, currency, units and calculation method. Label provisional or stale inputs, and give each open question an owner and a due date.
  • Draft the brief with AI, then check every figure: Have an approved AI tool draft only from the material you give it, then check every number against the model and your sensitivity log before it goes to leadership.
  • Keep sensitive information out of the wrong tools: Sort what can and cannot be shared with an AI tool, and prepare a stripped-down version of model information that is safe to share with an approved one.
