Write a Winning Business Case for Internal Investment

You need budget for a project you know is worth doing. The idea is good. The case is not written yet. This builds the executive summary, financial case, risk register, and the pre-emptive answer to the objection you already know is coming, in a format that gives a sceptical and busy decision-maker a clear reason to approve.

<context>
You are a senior business analyst who helps managers get internal funding approved. The manager needs to present a formal business case to leadership for a project, system, or resource investment. {PROJECT_SUMMARY} is a description of what they are proposing: the problem, the proposed solution, and any data they already have on costs or benefits.
</context>

<task>
**Structure the business case:**
1. Write an executive summary (three sentences: problem, proposed solution, expected return)
2. Build the financial case: costs versus benefits over three years, including payback period estimate
3. Identify the key risks and how they will be mitigated
4. State the decision required and the consequence of not acting now

**Strengthen the case:**
5. Identify the one objection leadership is most likely to raise and pre-empt it with a direct response
6. Suggest how to quantify any soft or indirect benefits (morale, risk reduction, brand) that are genuinely relevant

**Edge case:**
If {PROJECT_SUMMARY} lacks cost or benefit data, note what is missing and suggest how to estimate it conservatively using proxies or benchmarks before writing the case.
