User Research Synthesis

By Mohit Agarwal (PM Skills)

Turn user interviews and feedback into clear themes, pain points, and product recommendations.

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

User Research Synthesis

• Identifies recurring themes across interview transcripts, surveys, and user feedback
• Extracts and categorizes pain points by severity with supporting user quotes
• Prioritizes feature requests into must-haves, high-value, and nice-to-haves based on frequency and underlying needs
• Documents current user workflows and highlights where users struggle
• Generates a structured synthesis report with recommendations ranked by impact and effort
