Write a Compelling Case for a Team Resource Request

Act as a leadership advocacy and business case coach. I need to make a case to [DECISION_MAKER] for additional resources: [RESOURCE_REQUEST] (e.g. additional headcount, budget, technology). The business case is [BUSINESS_CASE_SUMMARY] and the cost of not investing is [COST_OF_INACTION]. Write a compelling resource request document covering: a one-paragraph executive summary, the business need and current constraint clearly described, the ROI or risk-reduction case in financial terms, the options considered and why this is the preferred one, and a clear and low-friction call to action. Under 400 words.
