The prompt

Create a cost-benefit analysis for the options I'm choosing between. Decision: [WHAT I'M DECIDING - e.g. "hire two analysts vs. buy a reporting tool vs. outsource"] Options: [LIST each option, including do nothing] Known costs: [one-time and ongoing costs for each, with sources] Expected benefits: [time saved, revenue, error reduction, risk reduced - with any numbers I have] Time horizon: [e.g. 3 years] Other factors that matter: [risk, speed, flexibility, employee impact, strategic fit] Steps: 1. For each option, list costs in two groups: one-time (purchase, implementation, training, transition) and recurring (licenses, salaries, maintenance, internal time). Add costs people usually forget and mark them [ADDED - CONFIRM]. 2. List benefits, separating hard benefits (cash saved or earned) from soft benefits (time freed, quality, morale). Do not convert soft benefits to money unless I give a basis. 3. Calculate per option: total cost over the horizon, total hard benefit, net benefit, and payback period. Show formulas so I can rebuild them in Excel. 4. Compare non-financial factors in a simple rating (high / medium / low). 5. Show which single assumption would change the ranking if it were wrong. Return: 1. A summary table: Option | One-time cost | Annual cost | Annual hard benefit | Net benefit over horizon | Payback | Key risk. 2. A non-financial comparison table. 3. The swing assumption and a break-even point for it. 4. A short recommendation with its main trade-off. Use only my numbers; write [NEED: ...] for gaps instead of guessing. For major financial commitments, have finance check the figures. The decision is mine.
