Business Case Stress Test

Ten structural questions that reveal whether a business case is built to be examined or built to be approved, answered from your knowledge of the case with nothing uploaded.

You do not upload the business case and no document is read or analysed by anything. You answer ten questions about how the case is constructed, and the fixed-point scoring shows where its structure would give way under an approver's pressure.

0–49 Weak business case structure 50–74 Needs strengthening 75–100 Stronger business case structure How our tools are scored
  1. Financial assumptions defined Are the assumptions behind the numbers visible?
    • Assumptions are implicit in the numbers
    • Listed, but without sources or owners
    • Listed with sources, owners and sensitivities
  2. Downside scenario included Does the case show what failure would actually cost?
    • Only the base case is presented
    • A downside exists, but it barely stings
    • A genuine downside is modelled with its consequences
  3. Alternatives compared Were other options developed, or just mentioned?
    • Only the preferred option is developed
    • Alternatives are named but not costed
    • Alternatives are costed, including doing nothing
  4. Implementation risks identified Does the case acknowledge how delivery could fail?
    • Risks are not addressed in the case
    • A generic risk list, without owners
    • Specific risks with owners and mitigations
  5. Ownership clear Is one person accountable for the benefits landing?
    • No single person is accountable for the benefits
    • An owner is named, but authority and capacity are unconfirmed
    • A named owner with the authority and capacity to deliver
  6. Dependencies listed Does the case name what it needs from elsewhere?
    • Dependencies are not identified
    • Known informally, but not documented
    • Documented and agreed with the teams that must deliver them
  7. Benefits quantified Are the benefits numbers anyone has agreed to own?
    • Benefits are described qualitatively
    • Quantified, but not accepted by the delivering functions
    • Quantified and signed off by the functions that must deliver them
  8. Timeline realistic Was the timeline built from the work or from a target date?
    • Set to a target date, not to the work
    • Plausible, but with no contingency
    • Built from the work, with contingency included
  9. External validation completed Has anyone outside the organisation tested the case?
    • No one outside the sponsoring team has tested it
    • Reviewed by internal audit or finance only
    • Tested by independent outsiders with relevant experience
  10. Decision criteria clear Do the approvers know what would make them say no?
    • The approval criteria are unstated
    • Criteria exist, but differ by approver
    • Approvers share explicit criteria for yes and for no
Reading the score

What the result bands mean

0–49: Weak business case structure

As described, the case is a recommendation wearing the clothes of an analysis. Without stated assumptions, compared alternatives or a genuine downside, approvers are being asked to endorse a conclusion rather than examine a case.

50–74: Needs strengthening

The skeleton of a sound case is present, but specific joints are weak: typically benefits nobody has signed up to deliver, timelines set by ambition, or validation that never left the building. These are the elements approvers probe first, and the ones that unravel first after approval.

75–100: Stronger business case structure

The case is structurally complete: assumptions, alternatives, downside and ownership are all visible. What structure cannot guarantee is honesty of inputs. A well-built case can still rest on a benefits figure that was reverse-engineered from the approval threshold.

No upload, no document analysis

This stress test never sees your business case. There is no upload, no text analysis and no AI reading anything: you answer ten questions from your own knowledge of the document, and fixed point values do the rest in your browser. That constraint is deliberate: the structural weaknesses that sink cases are ones the author already knows about when asked directly.

What the test examines

The ten questions cover the load-bearing elements of any investment case: whether the assumptions are visible enough to be challenged, whether alternatives were genuinely developed, whether anyone owns the benefits, and whether the approvers know what would make them say no. A case can have impeccable arithmetic and still fail all ten, because arithmetic is the easy part.

Who should stress-test the case

  • Authors who want to find the weaknesses before the investment committee does.
  • CFOs and approvers deciding how hard to push back on a case that reads well.
  • PMO and strategy teams setting a structural bar for cases entering the portfolio.

How the result is calculated

Each answer carries 0, 5 or 10 points, summed and normalised to 100, then mapped to one of three structural bands. Because the same answers always give the same score, the most useful pattern is the retest: strengthen the two weakest answers, run it again, and repeat until the structure stops being the problem.

Frequently asked questions

Why not just upload the business case and have it analysed?

Because the cases that matter are confidential, and because structural weakness is not a text-analysis problem. The author already knows whether anyone owns the benefits; the test simply forces that knowledge into the open without any document leaving your machine.

Our case scored well but was still rejected. What does that mean?

Structure gets a case examined fairly; it does not make the underlying investment good. Rejection of a well-structured case usually means the substance was tested and found wanting, which is the process working as intended.

Who should answer the questions, the author or a reviewer?

Both, separately. The gap between the author's score and a reviewer's score is one of the most revealing outputs: it shows where the case reads as complete to the person who wrote it and incomplete to everyone else.

A case that survives structure still has to survive scrutiny.
