One-page budget request memo

Help me write a one-page memo asking for budget. The reader is busy and will decide based on this page alone. Who decides: [their role and what they care about, for example cost control, growth, risk] What I'm asking for: [the amount and what it pays for] The problem it solves: [what's happening now and what it costs us in time, money or risk] Options I considered: [including doing nothing, with rough costs] Expected benefit: [what changes, and any numbers you have] Timing: [when you need a decision and why] Structure: 1. The ask, in one sentence, at the top. 2. The problem, in three sentences or fewer. 3. Options compared in a small table: cost, benefit, risk. 4. My recommendation and why. 5. What I'll report back on and when. Keep it under 350 words. Use my numbers only. Where I haven't given one, mark it [number needed] instead of inventing it. Then list the two toughest questions the decision-maker is likely to ask and how I might answer them.
