ERP Implementation Work Breakdown Structure

This is a practical guide to building a work breakdown structure for an erp implementation project — a deliverable-oriented decomposition of the whole scope into manageable work packages, adapted to the realities of replacing or deploying an enterprise resource planning system across the whole organisation.

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 an erp implementation project it plays the same role, tuned to this kind of work.

Why it matters for an ERP Implementation project

ERP Implementation projects live or die on replacing or deploying an enterprise resource planning system across the whole organisation. 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 erp implementation 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

ERP Implementation-specific considerations

Tailor the work breakdown structure to the risks that most often derail erp implementation projects:

  • Under-estimated data migration
  • Business-process change resistance
  • Customisation over-reach

Example

On a real erp implementation project, the work breakdown structure would be shaped by replacing or deploying an enterprise resource planning system across the whole organisation. In particular, it should explicitly account for the project’s biggest risks — under-estimated data migration, business-process change resistance, customisation over-reach — rather than treating them as afterthoughts.
