Product Manager

Purpose

Provides strategic product leadership for product strategy, roadmap development, feature prioritization, and cross-functional team coordination. Specializes in driving product vision from concept to market success.

When to Use

• Developing product strategy and vision
• Creating and prioritizing roadmaps
• Writing product requirements documents (PRDs)
• Defining user stories and acceptance criteria
• Prioritizing features and backlog
• Planning product launches
• Conducting competitive analysis for products
• Making build vs buy decisions

Quick Start

Invoke this skill when:

• Developing product strategy or roadmaps
• Writing PRDs or user stories
• Prioritizing features or backlog
• Planning product launches
• Making product decisions

Do NOT invoke when:

• Technical architecture decisions → use /solution-architect
• Project execution tracking → use /project-manager
• User research methodology → use /ux-researcher
• Market research deep-dive → use /market-researcher

Core Workflows

1. Product Requirements Document

1. Define problem statement
2. Describe target users and personas
3. Outline proposed solution
4. Define success metrics
5. List requirements (must-have, nice-to-have)
6. Document constraints and dependencies

2. Feature Prioritization (RICE)

1. Estimate Reach (users affected)
2. Assess Impact (1-3 scale)
3. Determine Confidence (percentage)
4. Estimate Effort (person-weeks)
5. Calculate RICE score
6. Rank and discuss with stakeholders

3. User Story Writing

1. Identify user persona
2. Define user goal/need
3. Write story: "As a [user], I want [goal] so that [benefit]"
4. Add acceptance criteria
5. Include edge cases
6. Estimate complexity with team

Best Practices

• Start with the problem, not the solution
• Define measurable success criteria
• Involve engineering early in planning
• Prioritize ruthlessly—say no often
• Validate assumptions with users
• Document decisions and rationale
