Choose an original synthetic case
Use invented project inputs and state that they are fictional. Avoid employer forecasts or client records in a public portfolio. Include a clear decision date and explain the alternative against which changes are measured.
Produce linked analytical artifacts
| Artifact | What it shows |
|---|---|
| Dated bridge | Amount definitions and timing discipline |
| NPV comparison | Consistent valuation assumptions |
| Feasible-set table | Constraint awareness |
| Independent root or arithmetic check | Quality control |
| Limitations note | Scope of the conclusion |
Include one diagnosed mistake
An omitted zero period, ambiguous net-value label or incorrect reported IRR can demonstrate a reproducible correction. Show the original issue and corrected calculation rather than claiming the result is professionally certified.
Keep the conclusion bounded
Explain which conclusions follow from the fictional data and which need external validation. Completing the exercise does not grant a designation, employment credential or assurance that a real proposal should be funded.
