+---
+
+# Phase 8: Product Evolution
+
+**Goal:** Improve existing products through targeted, incremental changes — running the full WDS pipeline in miniature for each improvement.
+
+**Your Role:** You work like a developer on the team. Pick a view that needs improving, scope it as a scenario, design the solution, implement it in a branch, test it, and deploy. Each cycle is one focused improvement.
+
+---
+
+## WORKFLOW ARCHITECTURE
+
+Phase 8 is **menu-driven**, not linear. Each activity is a compressed version of a full WDS phase.
+
+### Core Principles
+
+- **Brownfield First**: You're joining an existing product, not building from scratch
+- **Focused Scope**: One view, one scenario, one improvement at a time
+- **Full Pipeline in Miniature**: Analyze → Scope → Design → Implement → Test → Deploy
+- **Branch-Based**: Every change lives in its own branch until deployed
+- **Kaizen**: Small, incremental, data-driven — each cycle informs the next
+
+### Step Processing Rules
+
+1. **READ COMPLETELY**: Always read the entire step file before action
+2. **FOLLOW SEQUENCE**: Execute all sections in order
+3. **WAIT FOR INPUT**: Halt at decision points and wait for user
+4. **SAVE STATE**: Update design log when completing steps
+
+---
+
+## INITIALIZATION
+
+### 1. Configuration Loading
+
+Load and read full config from `{project-root}/_bmad/wds/config.yaml` and resolve:
+- `project_name`, `output_folder`, `user_name`
+- `communication_language`, `document_output_language`
+
+### 2. Design Log
+
+Read `{output_folder}/_progress/00-design-log.md`. Check Current and Backlog for context.
+
+### 3. Activity Menu
+
+```
+What would you like to do?
+
+[A] Analyze Product          — Understand current state, find improvement targets
+[S] Scope Improvement        — Create a scenario for a specific update
+[D] Design Solution          — Sketch and specify the update
+[I] Implement                — Code in a new branch
+[T] Acceptance Test          — Test against spec
+[P] Deploy                   — PR and deliver to the team
+```
+
+### Activity Routing
+
+| Choice | Workflow File | Steps | Borrows From |
+|--------|--------------|-------|--------------|
+| [A] | workflow-analyze.md | steps-a/ | Phase 3 (scenarios) |
+| [S] | workflow-scope.md | Inline | Phase 3 (scenarios) |
+| [D] | workflow-design.md | steps-d/ | Phase 4 (UX design) |
+| [I] | workflow-implement.md | Inline | Phase 5 (development) |
+| [T] | workflow-test.md | steps-t/ | Phase 5 [T] (testing) |
+| [P] | workflow-deploy.md | steps-p/ | Phase 4 [H] (delivery) |
