Fit Scorecards (PMF, BMF, SMF, bPMF)

Jason Hreha· Updated July 10, 2026

Use these checklists to make stage-gates explicit. Link each item to evidence (research notes, logs, datasets) and record thresholds in your Decision Memo.

The Behavior Fit Assessment is a practitioner decision tool for comparing candidate behaviors across Dispositional Fit, Capability Fit, and Context Fit. It is not a validated measurement instrument. Treat the minimum dimension as a bottleneck and prioritization heuristic; it is not a deterministic probability of behavior.

A score of 6 out of 10 on each Behavior Fit Assessment dimension is a starting threshold that must be calibrated by domain, population, context, stakes, and observed behavior.

Problem Market Fit (PMF) #

Problem definition is concrete; user language captured verbatim.
Evidence of solution-seeking behavior (searches, workarounds, prior spend).
Willingness signals (time/money/effort) documented for target segment.
Threshold met: [ ] Yes / [ ] No; Evidence: [link]

Behavior Market Fit (BMF) #

Target behavior defined operationally (who/what/when/where).
Provisional BFA ratings, evidence gaps, and the candidate minimum-dimension bottleneck are documented.
Any starting screen is calibrated for the domain, population, context, stakes, and observed behavior.
Real-context observation supports the BMF decision.
Users describe behavior as exciting/compelling in realistic probes.
Early prototypes show immediate reward/value upon completion.
Threshold met: [ ] Yes / [ ] No; Evidence: [link]

Solution Market Fit (SMF) #

First successful instance path ≤ steps target; minimal fields/choices.
TTFB median ≤ domain benchmark (e.g., < 5 min B2C; < 1 day B2B pilot).
Completion rate ≥ pre-registered threshold in pilot window.
Failure points instrumented and reduced across iterations.
Threshold met: [ ] Yes / [ ] No; Evidence: [link]

Behavioral Product-Market Fit (bPMF) #

Cohort definition and window (e.g., 30 days) documented.
D30/D180 behavior retention meets thresholds with denominators.
Unit economics and operations validated for sustained delivery.
Threshold met: [ ] Yes / [ ] No; Evidence: [link]
