Workflow

The 12-Section PRP Structure

A complete PRP contains these 12 sections:

1. Project Overview
2. Problem Statement
3. Success Criteria
4. User Stories (Jobs-to-be-Done)
5. Functional Requirements
6. Non-Functional Requirements
7. Technical Constraints
8. Data Requirements
9. UI/UX Requirements
10. Risks & Assumptions
11. Out of Scope
12. Open Questions

Let's dive into each:

---

1. Project Overview

Purpose: High-level context and pattern classification

What to Include:

• Project name and one-sentence description
• Pattern classification (A, B, or C)
• Timeline estimate
• Target users
• Business context

Example:

Project: Customer Support Chatbot
Pattern: C (AI-Native System)
Timeline: 10-12 weeks
Users: Customer support agents + end customers
Context: Reduce support ticket volume by 40% while maintaining customer satisfaction

---

2. Problem Statement

Purpose: Clearly define the problem being solved

Template:

[User type] faces [problem] when [situation].
This causes [negative outcome].
We know this because [evidence].

Example:

Customer support agents face long response times when customers ask common questions about billing, account setup, and feature usage. This causes customer frustration and agent burnout handling repetitive inquiries.

We know this because:
- 60% of tickets are "How do I..." questions
- Average response time is 4 hours
- Agent surveys show 70% of time spent on repetitive questions
- NPS dropped from 45 to 38 in past 6 months

---

3. Success Criteria

Purpose: Define measurable outcomes

Structure:

• Primary metric (North Star)
• Secondary metrics
• Minimum success thresholds

Example:

Primary Metric:
- Reduce support ticket volume by 40% within 3 months of launch

Secondary Metrics:
- 80% of common questions answered by AI without escalation
- <2 second response time for AI answers
- >4.0/5.0 user satisfaction rating with AI responses
- 50% reduction in agent time spent on common questions

Minimum Success:
- 30% ticket reduction + 4.0/5.0 satisfaction

---

4. User Stories (Jobs-to-be-Done)

Purpose: Capture user needs in job-to-be-done format

Template:

When [situation], I want to [action], so I can [outcome].

Example:

Customer Stories:
1. When I have a billing question, I want instant answers, so I can resolve issues without waiting.
2. When I'm setting up my account, I want step-by-step guidance, so I don't get stuck.
3. When I need to reset my password, I want a simple self-service flow, so I don't need to contact support.

Agent Stories:
1. When a complex issue arrives, I want context from the AI conversation, so I can help efficiently.
2. When training new agents, I want the AI to handle basics, so I can focus on teaching advanced topics.
3. When customers escalate, I want conversation history, so I don't ask redundant questions.

   - Mitigation: Confidence thresholds, human review for low confidence

2. Knowledge base quality risk
   - Mitigation: Content audit before launch, SME review of top 100 articles

3. User adoption risk (agents don't trust AI)
   - Mitigation: Gradual rollout, agent training, show accuracy metrics

4. API cost overruns
   - Mitigation: Aggressive caching, token limits, usage monitoring

Assumptions:
1. Customers will accept AI responses (validate with beta test)
2. Knowledge base is accurate and up-to-date (audit required)
3. 80% of questions can be answered with existing knowledge
4. OpenAI API latency is acceptable (<2s)

- Multi-language support (Phase 2)
- Integration with CRM system (future)
- Custom AI model training (using OpenAI)
- Mobile app (web only initially)
- Proactive outreach (reactive support only)
- Sentiment analysis dashboard (future analytics)
- Agent performance scoring (v2 feature)

Explicitly NOT Building:
- Custom LLM training (too expensive)
- Real-time translation (complexity vs. value)
- Video call integration (different project)

---

12. Open Questions

Purpose: Document unknowns that need answers

Structure:

• Question
• Who can answer
• When answer needed by
• Impact if not answered

Example:

Open Questions:

Q1: What's acceptable AI error rate for customers?
- Who: Product Manager + Customer Success lead
- Deadline: Week 2 (before architecture finalized)
- Impact: Determines confidence thresholds and escalation flow

Q2: Can we access historical conversation sentiment data?

Best Practices

1. Start with Problem, Not Solution

Write problem statement before functional requirements. Understand "why" before "what".

2. Make Success Criteria Measurable

Bad: "Improve user experience" Good: "Increase task completion rate from 60% to 85%"

3. Use Jobs-to-be-Done Format

Captures user intent, not just feature requests.

4. Be Explicit About Out of Scope

Prevents future arguments about "I thought we were building X".

5. Document All Open Questions

Don't hide unknowns. Make them visible and track resolution.

6. Update PRP as You Learn

PRPs evolve. Update when you discover new information.

7. Review with Stakeholders

Validate PRP with:

• Product Manager (business requirements)
• Engineering Lead (technical feasibility)
• Designer (UX requirements)
• Security (compliance requirements)

---

Common Pitfalls

1. Writing Solutions Instead of Requirements

Antipattern: "Use React with Redux for state management" Better: "System must handle real-time updates across multiple views"

2. Vague Success Criteria

Antipattern: "Users should be happy" Better: "NPS score >50, task completion rate >80%"

3. Missing Non-Functional Requirements

Antipattern: Only listing features Better: Include performance, security, scalability

4. Assuming Knowledge

Antipattern: "Obviously we need authentication" Better: Explicitly state all requirements

5. Mixing Pattern Complexity

Antipattern: Pattern A with Pattern C orchestration Better: Match PRP depth to pattern complexity
