BMad Module — Product Builder Method (PBM)

PBM brings structured product design and build to the BMad Method. From strategy to operations, PBM guides you through 6 sequential phases to ship a complete product.

About PBM

The Product Builder Method (PBM) adapts the BMad Method framework for end-to-end product development. PBM provides a structured, phase-driven approach covering strategic vision, user discovery, domain modeling, API specifications, implementation planning, and operations.

The 6 Phases

| # | Phase | Agents | Description | |---|-------|--------|-------------| | 1 | Strategy | Product Strategist | Define product vision, OKRs, initiatives, and positioning | | 2 | Discovery | Product Researcher | Understand users through personas, journeys, and product brief | | 3 | Design | Business Analyst, UX Designer, Solution Architect | Requirements, domain modeling, wireframes, OpenAPI specs, architecture, design system | | 4 | Plan | Product Manager | Structure features, stories, and Definition of Done | | 5 | Implementation | Software Engineer | Guided development with setup, CI/CD, feature implementation, code review | | 6 | Run | Ops Engineer | Observability, runbooks, incidents, SLA, on-call, continuity, support |

Transversal agents: Sales Consultant (commercial proposals, pricing) — Impact Analyst (cross-phase change propagation) — README Curator (project README maintenance). Not tied to a specific phase.

What PBM Does

• Strategic Alignment — Vision, OKRs, and initiative prioritization
• User Discovery — Personas, user journeys, and product brief
• Domain Modeling — Bounded contexts, models with JSON Schema, ubiquitous language
• Screen Specs — Wireframes, screen specifications, email specifications
• API Specifications — OpenAPI 3.x, split by bounded context
• Architecture — ADRs, security audit, infrastructure design, design system
• Implementation Plan — Features, stories, prioritization, coverage audit
• Guided Implementation — Setup, CI/CD, feature implementation, code review, debt management
• Operations — Observability, runbooks, incident management, SLA, chaos engineering
• Commercial Proposals — Pricing, packages, options, and sales argumentation
• Project README — Transversal skill to maintain the project README (stack, quickstart, conventions pointers)

Transversal Skills

These skills work across all phases:

| Command | Description | |---------|-------------| | /pbm-impact | Analyze the impact of a deliverable change and guide propagation | | /pbm-proposal | Build a complete commercial proposal with pricing | | /pbm-readme | Maintain the project README (stack, quickstart, conventions pointers) |

Installation

Direct install

npx @pbm-workflow/bmad-module-pbm install

Update

npx @pbm-workflow/bmad-module-pbm update

Quick Start

After installing, run from your project root:

/bmad-help              # Get guided help
/pbm-strategy           # Phase 1 — Strategy
/pbm-discovery          # Phase 2 — Discovery
/pbm-design             # Phase 3 — Design
/pbm-plan               # Phase 4 — Plan
/pbm-impl               # Phase 5 — Implementation
/pbm-run                # Phase 6 — Run

Two Ways to Work

| Approach | When to Use | Workflow | |----------|-------------|----------| | Full Method | Complete product build | Start with /pbm-strategy | | Jump In | Specific phase needed | Use any phase setup directly |

Visualizations

PBM includes interactive HTML files copied to your project during installation:

| File | Description | |------|-------------| | workflow-map.html | Interactive map of PBM phases and dependencies | | workflow-presentation.html | Slideshow presentation of PBM | | workflow-presentation-prompt.html | Prompt guide for presenting PBM |

Language

PBM workflows communicate in the language configured in your BMad setup. All domain terminology follows ubiquitous language conventions.
