Growth Experiment Prioritization Scorer
by @quochungto
Use this skill to score and rank a growth experiment backlog using the ICE framework (Impact, Confidence, Ease — each rated 1–10 and averaged) and select the...
Example 1: Series A — 20-Idea Backlog, Activation Sprint
A B2B SaaS team of 5 (growth PM, engineer, designer, marketer, data analyst) has 20 experiment ideas targeting activation — getting new trial users to the "aha moment" (≥3 team members using a shared project within 7 days). North Star: weekly collaborative sessions per team.
The scored backlog (abbreviated) looks like:
| Rank | Experiment | Impact | Confidence | Ease | ICE | Status | |------|------------|--------|------------|------|-----|--------| | 1 | Add progress bar to team setup wizard | 8 | 7 | 9 | 8.0 | Launch now | | 2 | In-app prompt to invite 2nd team member at step 3 | 8 | 8 | 7 | 7.7 | Launch now | | 3 | Email sequence: days 1, 3, 7 post-signup | 7 | 8 | 6 | 7.0 | Launch now | | 4 | Rebuild onboarding checklist UI | 9 | 6 | 3 | 6.0 | Pipeline: next sprint | | 5 | Integration with Slack for task notifications | 8 | 5 | 2 | 5.0 | Pipeline: 3 weeks (eng scoping) | | ... | ... | ... | ... | ... | ... | ... | | 19 | Add mascot to empty state screens | 3 | 4 | 8 | 5.0 | Drop | | 20 | Redesign marketing site hero | 4 | 3 | 2 | 3.0 | Drop |
Sprint selection: The growth PM selects experiments 1, 2, and 3 for the sprint (matching the team's capacity of 2–3 tests per week). Experiment 4 is slotted for the following sprint pending design mockups. Experiment 5 goes to engineering for a scope estimate. Experiments 19 and 20 are dropped — neither has a clear mechanism to increase collaborative sessions, which is the current NSM.
Example 2: Series B — 50-Idea Backlog, Retention Sprint
A marketplace team of 12 (two growth squads: acquisition + retention) needs to groom 50 ideas for a retention sprint targeting 90-day repeat purchase rate. North Star: orders per buyer per quarter.
Scoring challenge: The retention squad notices that 15 of the 50 ideas are acquisition ideas submitted by the other squad — they score well on Impact but target a different focus area. The growth lead moves all 15 to a separate acquisition backlog without scoring them in the retention sprint.
The remaining 35 retention ideas are scored. The top 8 (ICE ≥ 6.5) are selected for the sprint — 4 per squad per week. Ideas ranked 9–20 (ICE 4.5–6.4) are pipelined with dates. Ideas 21–35 (ICE ≤ 4.4) are reviewed for hypothesis quality: 5 are returned to submitters for clarification; 10 are dropped.
Key finding from the scoring: Three ideas that the retention squad assumed were quick (scoring themselves 8 on Ease) were recalibrated to Ease 4 by the growth lead after consulting the engineering team — all three required A/B test infrastructure that was not yet in place. Moving them to the pipeline freed up sprint slots for two mid-ranked ideas (ICE 6.2) that were genuinely fast to ship. The sprint launched on schedule.
