Rescore a feature backlog with RICE after a new estimate

Practice: Catching mistakes and made-up facts. About 5 minutes.

About this exercise

You're picking next quarter's first build using RICE (reach x impact x confidence ÷ effort). Write exactly 4 numbered lines, one per feature, each showing the math and score, then one unnumbered last line: Build first: [feature]. In this morning's standup, engineering re-estimated Slack alerts at 1.5 person-weeks (the sheet isn't updated yet). Ignore opinions that aren't in the scoring, plain text, under 90 words.

Common mistakes when you ask AI for this

  • Using the old estimate. The AI scores Slack alerts on 3 weeks and picks Dark mode. Try: Add: "Slack alerts effort is now 1.5 weeks, per today's standup."
  • Not asking to see the work. Without the math you can't spot a slipped decimal. Try: Add a line to copy: "1. Bulk export: 2,000 x 2 x 0.8 ÷ 4 = 800"
  • Letting opinions in. The AI weighs the CEO's ask or design's hunch into the pick. Try: Add: "Pick on score only. Ignore opinions not in the inputs."
  • Trusting the AI to count words. AI is bad at counting. Ask for a total word limit and it often lands over it. Try: Cap each line: "each line under 16 words."
  • Forgetting where it goes. AI loves markdown tables and bold, which show up as clutter in a planning doc comment. Try: Add: "Plain text, no bold, headings or tables."

What a strong prompt includes

  • Uses the new estimate
  • Defines the score
  • Asks to show the math
  • Asks for the pick last
  • Asks for plain text
