Business Case Best Practices
Key principles for strengthening business case governance and improving investment decisions at enterprise scale.
Why It Matters
Most business cases are written to win approval and then quietly abandoned, frozen at the moment of funding and rarely revisited. The portfolio carries the cost of that pattern in the form of stale assumptions, weakened accountability, and investment decisions that no longer reflect the conditions the organisation is actually operating in.
This guide treats the business case as a living portfolio tool rather than a one-time approval artefact, so investment decisions stay current, comparable, and tied back to strategy throughout delivery.
What This Guide Covers
- Spot the six common trapsRecognise the archetypes that weaken investment cases before they reach steering, so weak proposals don't reach the funding stage.
- Keep cases live throughout deliveryApply governance that keeps business cases current and comparable rather than frozen at approval.
- Fund initiatives in stagesRelease capital progressively as outcomes emerge, instead of writing a single cheque against an early-stage forecast.
- Structure stronger, decision-ready casesBuild business cases that are clear, balanced, and easy for governance forums to challenge constructively.
Use this guide to bring discipline to the way your portfolio commissions, governs, and challenges business cases at every stage of the investment lifecycle.
