Prioritization Frameworks (RICE, MoSCoW, Kano)

In short

Your backlog has 80 ideas and your team can build six. Prioritization frameworks don't decide for you, but they turn a shouting match into a fair conversation.

Structured ways to rank competing ideas — RICE scores Reach/Impact/Confidence/Effort, MoSCoW sorts into Must/Should/Could/Won't, and Kano separates basic expectations from delighters.

Think of it like this

Packing for the hostel

Your suitcase fits only so much. Laptop and charger are musts. The extra hoodie is a should. The fourth pair of shoes is a won't. You also pick small, light things that matter a lot. That's MoSCoW and RICE in a suitcase.

1/5Five ideas, all "important" to someone. RICE scores each one: Reach x Impact x Confidence / Effort.

The big ideas

What you need to know

RICE: a score

Reach (users per quarter) x Impact (0.25 to 3) x Confidence (%) / Effort (person-months). Higher goes first.

MoSCoW: four buckets

Must have, Should have, Could have, Won't have this time. Great for fixing release scope with stakeholders.

Kano: how users feel

Basics cause anger if missing. Performance features please more as they improve. Delighters surprise users who didn't expect them.

Frameworks start talks

Scores are estimates. Use them to expose assumptions, then apply judgement.

See it in code

A tiny example

excel

1=(B2 * C2 * D2) / E2

In Google Sheets, put Reach in B, Impact in C, Confidence as a decimal in D and Effort in E. Fill the formula down, then sort by it.

Save yourself the pain

Common mistakes

Oops

Tweaking RICE numbers until your favourite idea wins.

Do this instead

Agree on how you'll estimate each factor first, and write down where each number came from.

Oops

Marking everything as a Must have.

Do this instead

A Must is something the release fails without. If it could slip a week, it's a Should.
