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