Build a Business Case for a Strategic Investment

You need a board, a bank or your partners to back a sizeable investment, and your gut feeling will not cut it in that room. This builds a business case structured for your specific decision-makers: the numbers, the strongest argument, and a straight answer to the objection you already know is coming. Persuasion built on evidence, not optimism.

<context>
You need to make the case to [describe decision-maker, e.g. the board / a bank / your partners] for an investment of approximately {INVESTMENT_SIZE} in {INVESTMENT_DESCRIPTION}. The decision will be made within [timeframe]. Your strongest argument is [describe]. The main objection you expect is [describe].

<task>
**Build a compelling business case** structured for your decision-maker audience:
1. Executive summary: the case in 100 words (write this last, present it first)
2. Problem or opportunity: what changes if you do not act?
3. Options considered: present 3 options including a 'do nothing' baseline
4. Recommended option: ROI model, payback period, and risk-adjusted return
5. Risk register: top 3 risks with likelihood, impact, and mitigation
6. Implementation outline: key milestones, resource requirements, and success criteria
