Review Criteria -- Product Discovery Review

Evidence Quality Validation

Past Behavior Indicators (Good)

"Tell me about the last time..." | "When did you last..." | "What happened when..." | "Walk me through how you..." | "What did you try..." | "How much have you spent on..."

Specific dates, dollar amounts, named tools, concrete examples, emotional frustration language

Future Intent Red Flags (Reject)

"Would you use/pay/like..." | "Do you think..." | "Imagine if..." | "What if we..."

Flag and reject if >20% of evidence is future-intent.

Validation Thresholds

• Past behavior ratio: >80% (reject if fail, require re-interview)
• Specific examples: min 3 concrete per finding (warn if fail)
• Customer language: quotes in customer words, not paraphrased (warn if fail)

Sample Size Minimums

| Phase | Minimum | High Confidence | Notes |

|-------|---------|-----------------|-------|

| 1: Problem | 5 | 10 | Interviews required |

| 2: Opportunity | 10 | 20 | Quantitative supplements, not replaces |

| 3: Solution | 5 per iteration | 3 iterations max | Before decision |

| 4: Viability | 5 | -- | Stakeholder review required |

Pivot decision rule: min 5 consistent signals. Block decisions on fewer.

Decision Gate Criteria

G1: Problem to Opportunity

Proceed: 5+ confirm pain + willingness to pay | Pivot: differs from expected | Kill: <20% confirm

Checks: 5+ interviews, >60% confirmation, customer words, 3+ examples

G2: Opportunity to Solution

Proceed: top 2-3 score >8 (0-20) | Pivot: new opportunities | Kill: all low-value

Checks: OST complete with 5+, scores correct (Importance + Max(0, Importance - Satisfaction)), top >8/20

G3: Solution to Viability

Proceed: >80% task completion, usability validated | Pivot: needs refinement | Kill: fundamental blocks

Checks: 5+ users/iteration, >80% completion, core flow usable, value validated

G4: Viability to Build

Proceed: 4 risks addressed, model validated | Pivot: adjustment needed | Kill: no viable model

Checks: Lean Canvas complete, all risks green/yellow, stakeholder sign-off

Bias Types

Confirmation Bias (critical)

Signals: only positive quotes | skeptics not interviewed | disconfirming evidence dismissed | same questions for "right" answers

Fix: include skeptics, actively seek disconfirming evidence

Selection Bias (high)

Signals: all existing customers | no churned/non-adopters | lacks diversity | single-enthusiast referral chain

Fix: random/diverse selection, include skeptics and non-users

Discovery Theater (critical)

Signals: conclusion decided before research | findings match hypothesis perfectly | no surprises | idea-in = idea-shipped

Fix: track idea evolution, expect 50%+ ideas to change

Sample Size Problem (high)

Signals: major decisions on 2-3 interviews | single quote as "validation" | pivot on one signal

Fix: min 5 interviews per segment, 5+ signals for decisions

Anti-Patterns

Interview Anti-Patterns

| Pattern | Detection | Bad | Good | Severity |

|---------|-----------|-----|------|----------|

| Leading questions | Suggests desired answer | "Don't you think this would save time?" | "Tell me about the last time you tried to save time on this" | high |

| Future-intent | Hypothetical behavior | "Would you use this feature?" | "What have you tried to solve this problem?" | critical |

| Compliments as validation | Accepting "that's cool" | "They loved the idea!" | "They committed to follow-up and referral" | high |

| Talking > listening | >30% interviewer talk | Long questions, short responses | Open questions, extended answers | medium |

Process Anti-Patterns

| Pattern | Detection | Severity |

|---------|-----------|----------|

| Skipping to solutions | Solution before problem validated | critical |

| Demographic segmentation | Segments by demographics not jobs | medium |

| Building before testing | Code before Phase 3 | critical |

Strategic Anti-Patterns

| Pattern | Detection | Severity |

|---------|-----------|----------|

| Premature pivoting | Direction change on 1-2 signals (need 5+) | high |

| Solution love | Defending despite evidence, dismissing critics | high |

| Sole source of truth | Only quant OR qual, not both | medium |
