The Business Case Structure
3 min read
A business case is an argument with numbers. The structure follows the same logic as any persuasive argument: establish the problem, quantify the cost of the problem, present the solution, quantify the benefit of the solution, and prove the return exceeds the investment. Every section must be supported by data. Every number must be traceable. A business case that says "we believe this will improve productivity" is an opinion. One that says "based on the pilot, this reduced task time by 34%, saving 12 hours per week across 8 team members, which equates to $124,800 annually at fully loaded cost" is a case.

Do This
- Lead with the executive summary — decision-makers read this first and sometimes only this
- Include alternatives considered and explain why they were rejected
- Quantify the cost of doing nothing — inaction has a cost too
Avoid This
- Build the case bottom-up and save the conclusion for the last page — front-load the answer
- Present only one option — a business case without alternatives is a foregone conclusion, not an analysis
- Skip the risk section — a case with no risks acknowledged is a case the CFO does not trust
