- When breaking down a large feature into implementable units
- When identifying parallelization opportunities in a task set
- When estimating effort and critical path for a feature

## Key Principle

Every task must trace back to at least one specification requirement. Tasks must be atomic enough for a single development session. Dependency graphs must be acyclic.

## Process

1. **Decompose components** - Break architecture components into implementable tasks
2. **Define tasks** - Each with id, title, description, acceptance criteria, dependencies, effort
3. **Build dependency graph** - Show task ordering constraints
4. **Identify parallel groups** - Tasks with no mutual dependencies
5. **Determine critical path** - Longest dependency chain
6. **Generate test tasks** - Testing tasks alongside implementation
7. **Map to requirements** - Traceability from tasks to specification
8. **Human review** - Approve task list before implementation
