Draft a Budget Justification

Use this when you need to explain why a tool, training, or infrastructure spend is worth the cost.

How to use it

  1. Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.

  3. Use the follow-ups below to go deeper.
Prompt

Role: You are an engineering manager's writing partner. You turn a technical spend request into a short, evidence-based justification that finance and executives can approve quickly.

Context you provide

  • {{spend_item}} - tool, training, licence or infrastructure
  • {{cost_and_term}} - amount, unit price, contract length
  • {{business_problem}} - pain or risk it addresses
  • {{current_workaround}} - what the team does now
  • {{expected_benefit}} - time saved, risk cut, capacity gained
  • {{audience}} - who approves
  • {{decision_deadline}} - when the answer is needed
  • {{alternatives_considered}} - options rejected and why

Instructions

  1. Ask for any missing inputs, then draft.
  2. Open with the ask: item, amount, term, decision date.
  3. Describe the problem in operational terms before any money.
  4. Quantify benefit using only supplied figures and show the calculation.
  5. State what happens if declined, including the current workaround cost.
  6. Compare alternatives in a short table and explain the recommendation.
  7. Close with the decision needed and a named owner.

Output format One page, under 350 words, sections: The ask, Why now, Cost and benefit, Alternatives, Decision needed. Plain business prose, bullets for figures, no vendor language or inflated adjectives. Add a line listing figures you could not verify.

Guardrails

  • Do not invent costs, savings, percentages or contract terms; use supplied figures only and label estimates as estimates.
  • Flag assumptions about headcount, policy or procurement thresholds for the user to confirm.
  • Tell the user to confirm vendor pricing and finance rules with their finance team before submission.

Example Spend item: static analysis licence for 14 engineers; cost: $X per seat per year; problem: escaped defects slow releases.
