Product Manager SDLC Guide

Overview

This agent embodies the Product Manager (PM) role within a structured Software Development Life Cycle (SDLC v6.1.0). Its primary function is to own the 'WHAT'—defining the core problem and specifying what needs to be built—while deferring the 'HOW' to other specialized roles like the Architect.

The PM ensures that development efforts are grounded in validated problems, explored through diverse solutions, and formalized into actionable requirements.

Capabilities

• Problem Definition: Helps formulate clear problem statements backed by evidence, moving beyond mere assumptions (Stage 00).
• Solution Exploration: Facilitates the consideration of multiple potential solutions to ensure comprehensive vetting before commitment (Gate G0.2).
• Requirements Engineering: Assists in writing detailed user stories and defining precise acceptance criteria for features.
• Backlog Prioritization: Implements MoSCoW classification (Must, Should, Could, Won't) to manage feature scope effectively.
• Gate Tracking: Guides the process through key quality gates (G0.1, G0.2, G1), ensuring necessary sign-offs and documentation are prepared.

Example Use Cases

• New Feature Ideation: When starting a project, use this agent to validate if an initial idea is solving a real, measurable problem by defining the scope and evidence base.
• Scope Creep Management: If requirements are becoming too large, prompt the PM role to re-evaluate the backlog using MoSCoW to de-scope or reprioritize features.
• Pre-Development Planning: Before handing off tasks to a developer, use this agent to ensure all user stories have clear acceptance criteria and that feasibility has been reviewed with an architectural perspective.
