SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps teams rigorously measure Product-Market Fit (PMF) to understand if their product is a "must-have" for a specific segment, identify drivers of value, and diagnose potential PMF drift.

Core Features & Use Cases

  • PMF Measurement: Triangulates signals from surveys (Sean Ellis method), behavioral data (retention/engagement), and customer advocacy.
  • Actionable Insights: Produces a PMF Scorecard, diagnosis by segment, and a prioritized action plan.
  • Use Case: A growth team can use this Skill to determine if their product has achieved PMF for a target segment before scaling acquisition spend, or to diagnose why PMF might be eroding.

Quick Start

Use the measuring-product-market-fit skill to measure PMF for your product, focusing on the B2B SaaS segment.

FAQPage Schema
How do I measure product-market fit for a B2B SaaS product?

Measure product-market fit by triangulating Sean Ellis survey data, behavioral retention analytics, and customer advocacy signals. This approach assesses PMF across defined segments to diagnose current status, identify value drivers, and detect potential PMF drift for B2B SaaS products.

What is the Sean Ellis survey method for assessing PMF?

The Sean Ellis survey method is a customer feedback technique used to determine if a product is a must-have. It is triangulated with behavioral retention data and customer advocacy signals to diagnose PMF status across defined segments.

Why does product-market fit erode for specific customer segments?

Product-market fit erodes due to PMF drift, which occurs when value drivers shift within segments. Diagnosing this drift requires triangulating behavioral retention analytics, Sean Ellis survey data, and customer advocacy signals to identify the root causes.

How do I create an action plan after measuring product-market fit?

Create a PMF action plan by generating a PMF Measurement Pack that includes a scorecard, diagnosis by segment, and prioritized actions. This pack also defines a re-measurement cadence to continuously track PMF drift over time.

Can I use behavioral retention data to diagnose product-market fit drift?

Yes, behavioral retention data is used to diagnose PMF drift. It is triangulated with Sean Ellis survey results and customer advocacy signals to assess PMF status across segments and identify drivers of value.

What is the best way to track product-market fit before scaling acquisition spend?

Track product-market fit before scaling acquisition by measuring PMF across a target segment using Sean Ellis survey data, behavioral retention analytics, and customer advocacy signals. Generate a scorecard to ensure the product is a must-have before investing.
