--- title: "The Four Phases of BMad Method" description: Understanding the four phases of the BMad Method --- BMad Method uses a four-phase approach that adapts to project complexity while ensuring consistent quality. --- ## Phase Overview | Phase | Name | Purpose | Required? | |-------|------|---------|-----------| | **Phase 1** | Analysis | Exploration and discovery | Optional | | **Phase 2** | Planning | Requirements definition | Required | | **Phase 3** | Solutioning | Technical design | Track-dependent | | **Phase 4** | Implementation | Building the software | Required | --- ## Phase 1: Analysis (Optional) Exploration and discovery workflows that help validate ideas and understand markets before planning. **Workflows:** - `brainstorm-project` - Solution exploration - `research` - Market/technical/competitive research - `product-brief` - Strategic vision capture **When to use:** - Starting new projects - Exploring opportunities - Validating market fit **When to skip:** - Clear requirements - Well-defined features - Continuing existing work --- ## Phase 2: Planning (Required) Requirements definition using the scale-adaptive system to match planning depth to project complexity. **Workflows:** - `prd` - Product Requirements Document (BMad Method/Enterprise) - `tech-spec` - Technical specification (Quick Flow) - `create-ux-design` - Optional UX specification **Key principle:** Define **what** to build and **why**. Leave **how** to Phase 3. --- ## Phase 3: Solutioning (Track-Dependent) Technical architecture and design decisions that prevent agent conflicts during implementation. **Workflows:** - `architecture` - System design with ADRs - `create-epics-and-stories` - Work breakdown (after architecture) - `implementation-readiness` - Gate check **Required for:** - BMad Method (complex projects) - Enterprise Method **Skip for:** - Quick Flow (simple changes) **Key principle:** Make technical decisions explicit so all agents implement consistently. --- ## Phase 4: Implementation (Required) Iterative sprint-based development with story-centric workflow. **Workflows:** - `sprint-planning` - Initialize tracking - `create-story` - Prepare stories - `dev-story` - Implement with tests - `code-review` - Quality assurance - `retrospective` - Continuous improvement **Key principle:** One story at a time, complete each story's full lifecycle before starting the next. --- ## Phase Flow by Track ### Quick Flow ``` Phase 2 (tech-spec) → Phase 4 (implement) ``` Skip Phases 1 and 3 for simple changes. ### BMad Method ``` Phase 1 (optional) → Phase 2 (PRD) → Phase 3 (architecture) → Phase 4 (implement) ``` Full methodology for complex projects. ### Enterprise ``` Phase 1 → Phase 2 (PRD) → Phase 3 (architecture + extended) → Phase 4 (implement) ``` Same as BMad Method with optional extended workflows. --- ## Related - [Why Solutioning Matters](./why-solutioning-matters.md) - [Preventing Agent Conflicts](./preventing-agent-conflicts.md) - [Quick Start Guide](../../tutorials/getting-started/getting-started-bmadv6.md)
