Fit Scorecards (PMF, BMF, SMF, bPMF)

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

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).
• Feasibility (BSM min‑component ≥ 6) for median target user.
• 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]
