Prioritising experiments: ICE vs. RICE
In short
ICE scores impact, confidence and effort. RICE adds reach and divides by effort. ICE is faster and usually enough for small teams; RICE pays off with many users and several product surfaces. Both only work when scoring is documented and repeatable.
Comparison
| ICE | RICE | |
|---|---|---|
| Factors | Impact, confidence, effort | Reach, impact, confidence, effort |
| Overhead | low | medium |
| Suits | small teams, fast cycles | larger products |
What goes wrong
- Confidence as gut feel instead of evidence
- Effort without an engineering estimate
- Scoring by one person alone
- A backlog that is never rescored

Growth hacking for brands
Growth hacking is a process, not a trick: measure the funnel, prioritise hypotheses, run clean experiments, document results, scale winners. ViralBP builds that loop including tracking, so growth becomes repeatable instead of accidental.
FAQ
How often should you rescore?
Every sprint or month. Results change confidence, and therefore the order.
