Process Improvement Work Breakdown Structure
This is a practical guide to building a work breakdown structure for a process improvement project — a deliverable-oriented decomposition of the whole scope into manageable work packages, adapted to the realities of improving an existing business process.
What a Work Breakdown Structure is
A work breakdown structure is a deliverable-oriented decomposition of the whole scope into manageable work packages. For the full concept and how it works in general, see Work Breakdown Structure. On a process improvement project it plays the same role, tuned to this kind of work.
Why it matters for a Process Improvement project
Process Improvement projects live or die on improving an existing business process. A well-built work breakdown structure gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how process improvement projects drift into avoidable delay and cost.
What to include
- Top-level deliverables
- Sub-deliverables
- Work packages (8–80 hours)
- WBS numbering
- WBS dictionary entries
Process Improvement-specific considerations
Tailor the work breakdown structure to the risks that most often derail process improvement projects:
- Change resistance
- Measuring the baseline
- Scope discipline
Example
On a real process improvement project, the work breakdown structure would be shaped by improving an existing business process. In particular, it should explicitly account for the project’s biggest risks — change resistance, measuring the baseline, scope discipline — rather than treating them as afterthoughts.
