Prioritisation frameworks do not tell you what to build. They make your reasoning explicit enough to argue with, which turns out to be the more valuable property.
RICE and its weak link
RICE scores reach, impact, confidence and effort, dividing the first three by the last. Its strength is forcing a numeric estimate of effort against value rather than an intuition.
Its weakness is that impact is usually guessed. The confidence multiplier is meant to discount that, and it works only if people apply it honestly. Where a team has no strong prior, RICE mostly launders a guess into a number.
MoSCoW for scoping a release
Must, Should, Could and Won't is a scoping tool, not a ranking one. Its real value is the Won't column, which makes exclusions explicit and dated rather than leaving them to resurface repeatedly.
It works well for a fixed-deadline release and poorly for a continuous backlog, where everything drifts into Must over time.
- RICE: comparing many independent items with reasonable data.
- MoSCoW: scoping a single release against a fixed date.
- Kano: deciding between delighters and basic expectations.
- Cost of delay: sequencing when timing genuinely changes value.
Kano separates delight from expectation
Kano classifies features as basic expectations, performance attributes or delighters. Basics generate no satisfaction when present and severe dissatisfaction when absent — data export is a good example.
The practical lesson is that shipping a delighter while a basic expectation is missing does not net out positive. Fix the absent basics first, however unexciting they look on a roadmap.
How we actually decide
We use RICE for a rough ordering, then override it deliberately for strategic bets and for anything blocking a customer commitment. The framework is an input to the argument, not the verdict.
The discipline that matters most is not the scoring. It is writing down why an item was chosen over its neighbours, so that when priorities shift next quarter the team can tell whether the reasoning changed or only the mood.
Key takeaways
- Frameworks make reasoning arguable; they do not produce answers.
- RICE's impact figure is usually a guess — apply confidence honestly.
- MoSCoW's real value is an explicit Won't column.
- Missing basic expectations outweigh any delighter you ship.
