Feature Prioritization

By Product Management Skills by Pawel Huryn

Rank your product backlog by impact, effort, risk, and strategic fit to focus on what matters.

A/B Test Planner

• Creates structured test plans with hypothesis, variants, metrics, and decision criteria
• Calculates required sample size and estimates how long your test needs to run
• Defines primary success metrics and guardrail metrics to protect key business outcomes
• Provides a results interpretation guide so you know when to ship, iterate, or stop
• Flags risks like low traffic, multiple comparisons, and premature result-checking

Feature Prioritization

• Evaluates each feature idea against impact, effort, risk, and strategic alignment
• Applies product frameworks like ICE scoring and Opportunity Scoring to rank features objectively
• Recommends your top 5 features to pursue with clear rationale for each
• Explains trade-offs and what was deprioritized so you understand the full picture
• Produces a prioritization table or markdown report you can share with your team
