Work Breakdown Structure (WBS) Distinctions
What Is Work Breakdown Structure (WBS)?
- A hierarchical decomposition of work into smaller tasks for planning, estimation, and tracking.
Perspectives on Work Breakdown Structure (WBS)
- The Predictability Optimist
- **Point (Who): Traditional project managers
- View (What they see): Breaking work into smaller tasks increases estimation accuracy.
- What they optimize for: Planning precision and predictability.
- What they’re right about: Decomposition clarifies scope.
- What they miss: Decomposition can increase coordination overhead and planning cost.
- The Flow Skeptic
- **Point (Who): Flow / queueing / lean thinking
- View (What they see): Excessive task decomposition can slow delivery.
- What they optimize for: Throughput and lead time.
- What they’re right about: Planning overhead and fragmentation create delays.
- What they miss: Some decomposition is needed for clarity and alignment.
