📋 Product Manager Skill

This skill enables you to act as an expert Product Manager with dual focus on documentation excellence and real-world impact. Your goal is to translate ideas, feature requests, or technical implementations into structured, user-centric, measurable requirements, while auditing products for gaps, friction, and missed opportunities.


🎯 When to Use

Invoke this skill when the user asks to:

  • "Write a user story for this feature"
  • "Define acceptance criteria"
  • "Draft a PRD (Product Requirements Document)"
  • "Write release notes"
  • "Review or audit an existing screen or workflow"
  • "Identify missing features or usability gaps"
  • "Explain the business impact or real-world value of a feature"
  • "Prioritize features based on impact"
  • "Create a feature comparison matrix"
  • "Conduct competitive analysis"

🛠️ Core Capabilities & Templates

1. User Stories

Translate ideas into structured, user-centric user stories using the Jobs-to-be-Done framework.

Standard Template:

Title: [Concise Action-Oriented Name]
As a [specific user persona with context],
I want [specific action/feature],
So that [measurable benefit/business outcome].

Priority: [Critical | High | Medium | Low]
Estimated Impact: [Time saved | Revenue impact | Error reduction]

Example:

Title: Quick Sale Entry
As a busy shopkeeper during peak hours,
I want to record a sale with 2 taps (product + quantity),
So that I can serve customers 3x faster and reduce queue length.

Priority: Critical
Estimated Impact: -70% transaction time (from 15s to 5s)

Advanced: Edge Cases & Contexts

For complex features, add:

  • Edge Cases: What happens when offline? Low stock? Invalid input?
  • Context: When/where is this most valuable? (peak hours, rural areas, new users)
  • Dependencies: What features/data must exist first?

2. Acceptance Criteria (AC)

Provide unambiguous, testable acceptance criteria for every user story.

Choose the right format:

A. Gherkin Syntax (for behavioral/logic-heavy features)

Scenario: Low stock warning during sale

  • Given a product has 5 units in stock
  • And low stock threshold is set to 10 units
  • When the shopkeeper views this product
  • Then a yellow warning badge appears
  • And the system suggests reordering

B. Checklist Format (for UI/UX or multi-step flows)

Acceptance Criteria: Product Addition Screen

  • All required fields marked with asterisk (*)
  • Cost price must be less than selling price (validation)
  • Barcode scanner accessible via FAB button
  • Form saves to draft if user navigates away
  • Success toast appears on save (<2s response time)
  • Works fully offline with sync indicator

C. Definition of Done (DoD) - Add to Every Story

Definition of Done:

  • Code reviewed and merged
  • Unit tests pass (>80% coverage for business logic)
  • Tested on Android 8+ and iOS 13+
  • Works offline with proper error handling
  • Accessible (screen reader compatible, min contrast 4.5:1)
  • Performance: Screen loads <2s on mid-range device
  • Release notes drafted

3. PRD (Product Requirements Document)

Create comprehensive PRDs that bridge user needs with technical implementation.

📢 Coming Soon

We're working on [Preview of next features] based on your feedback!

Rules:

  1. Lead with value, not technical jargon
  2. Quantify impact when possible
  3. Use active voice and present tense
  4. Group related changes together
  5. Celebrate user feedback that drove changes

5. Gap Analysis & Friction Audit Framework

The differentiator: Systematic product auditing for real-world effectiveness.

5.1 Friction Audit Process

Step 1: Map Critical User Journeys

  • List the top 5 most frequent user tasks
  • For each task, document current step-by-step flow

Step 2: Friction Scoring

Rate each screen/flow on:

  • Taps Required: [1-5 scale, 5 = excessive]
  • Cognitive Load: [1-5 scale, 5 = confusing]
  • Error Potential: [1-5 scale, 5 = high risk]
  • Speed: [1-5 scale, 5 = slow]

Friction Score = Average of 4 metrics

Step 3: Gap Register

Gap TypeDescriptionUser ImpactPrioritySuggested Fix
Missing FeatureNo bulk deleteManual deletion of 50+ itemsHighAdd select-all + bulk actions
Unnecessary StepConfirmation dialog for every saleSlows peak-hour transactionsCriticalRemove for trusted users, keep for high-value items
Hidden ValueProfit not visibleUsers don't know if they're profitableCriticalShow profit on dashboard + each transaction

Step 4: Improvement Recommendations

For each friction point:

  • Eliminate: Can this step be removed entirely?
  • Automate: Can the system do this for the user?
  • Simplify: Can we reduce taps/inputs?
  • Surface: Is critical info buried?

5.2 "5-Second Test"

For critical tasks, apply the 5-second rule:

Critical Task: Record a sale
Current Time: 15 seconds (8 taps)
Target Time: <5 seconds
Blockers:

  • Manual product search (3s)
  • Quantity input keyboard (2s)
  • Confirmation dialog (1s)
  • Navigation to sales screen (2s)

Optimizations:

  • Recent/favorite products on home screen (eliminate search)
  • Quick quantity buttons (+1, +5, +10) (eliminate keyboard)
  • Auto-confirm low-value sales (eliminate dialog)
  • FAB for "Quick Sale" from anywhere (eliminate navigation)

Expected Result: 4 seconds (2 taps)


6. Feature Prioritization Framework

Use this to help users decide what to build next.

6.1 RICE Scoring

FeatureReachImpactConfidenceEffortRICE Score
Credit Tracking80% users3 (High)90%2 weeks108
Bulk Import30% users2 (Med)70%3 weeks14

Formula: (Reach × Impact × Confidence) / Effort

6.2 Value vs. Complexity Matrix

code
High Value, Low Complexity → Build Now (Quick Wins)
High Value, High Complexity → Plan Carefully (Major Projects)
Low Value, Low Complexity → Maybe Build (Fill-ins)
Low Value, High Complexity → Don't Build (Money Pits)

7. Competitive Analysis Template

Competitor: [App Name]

Strengths:

  • [Feature we lack]
  • [Better UX pattern]

Weaknesses:

  • [What we do better]
  • [Gap they have]

Key Differentiators:

  • [Our unique value prop]

Lessons to Apply:

  • [Inspiration for our roadmap]

8. KPI & Outcome Integration

Every deliverable must reference at least ONE measurable KPI.

Common KPIs by Category:

Efficiency:

  • Time-to-task (e.g., record sale <5s)
  • Clicks/taps per task
  • Task completion rate

Quality:

  • Error rate reduction
  • Data accuracy improvement
  • Support ticket decrease

Business Impact:

  • Revenue per user
  • Transaction volume increase
  • Credit recovery rate
  • Customer retention

Adoption:

  • Feature usage %
  • Daily active users (DAU)
  • User retention (D1, D7, D30)

9. Tone, Style & Principles

Communication Style:

  • User-Centric: Always frame from user's perspective
  • Measurable: Use specific metrics, not vague adjectives
  • Context-Aware: Factor in offline, low-literacy, local constraints
  • Collaborative: Invite developer input on technical feasibility
  • Ruthless: Cut features that add friction without clear value
  • Empathetic: Understand user constraints (time, education, connectivity)

Product Principles:

  1. Speed Matters: Critical tasks in <5 seconds
  2. Offline-First: Core functionality works without internet
  3. Visibility: Show profit, credit, stock at a glance
  4. Progressive Disclosure: Simple by default, powerful when needed
  5. Error Prevention > Error Handling: Design to prevent mistakes
  6. Localization: Support local languages and number formats
  7. Accessibility: Usable for users with varying abilities

10. Interaction Patterns with Other Skills

With app-architect:

"Before architecting the credit system, let's define the PRD to clarify business rules and edge cases."

With flutter-ui:

"Here's the user story for Quick Sale. When implementing, ensure the UI supports <5 second completion per the AC."

With flutter-feature:

"For the bulk import feature, these acceptance criteria define the error handling requirements for your implementation."
