What Is a PMF Workbook?

A PMF workbook is a structured set of exercises designed to help you evaluate your product’s performance in the market. It focuses on areas like customer satisfaction, retention, growth, and competitive advantage. By completing these exercises, you’ll gain a clear understanding of: Who your customers are.How well your product is solving their problems.Whether your growth metrics are sustainable. The workbook isn’t just theoretical; it’s actionable. Each section guides you through collecting data, analyzing patterns, and pinpointing what needs to change.

What’s Inside the PMF Workbook?

  1. Understanding Your Customers
This exercise helps you define your target audience and understand the problems they face. You’ll outline your customer segments, their pain points, and how your product solves these issues. Outcome: A clear picture of your product’s alignment with customer needs.
  1. The “40% Rule” Survey
This is a survey-based exercise where you ask your customers, “How would you feel if you could no longer use our product?” If at least 40% respond with “very disappointed,” you’re likely close to PMF. Outcome: A measurable way to gauge customer dependency on your product.
  1. Retention Curve Analysis
Retention curves show how many users stick around over time. A flat curve is a strong indicator of PMF, while steep drop-offs suggest issues with engagement or onboarding. Outcome: Insights into user behavior and the product's ability to keep them engaged.
  1. Growth and Virality
Here, you track metrics like your monthly active users, growth rate, and viral coefficient (how many users a single customer refers). Sustainable growth is a key signal of PMF. Outcome: A snapshot of your growth potential and customer acquisition efficiency.
  1. Customer Feedback Patterns
This exercise organizes feedback into patterns, highlighting recurring themes in what customers love, dislike, or want improved. Outcome: Actionable feedback to guide product development.
