ERP Implementation Business Case
This is a practical guide to building a business case for an erp implementation project — the justification that weighs the costs, benefits and risks of doing the project, adapted to the realities of replacing or deploying an enterprise resource planning system across the whole organisation.
What a Business Case is
A business case is the justification that weighs the costs, benefits and risks of doing the project. For the full concept and how it works in general, see Business Case. 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 business case 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
- Problem or opportunity
- Options considered
- Costs and benefits
- Financial appraisal (ROI/NPV/IRR)
- Recommendation
ERP Implementation-specific considerations
Tailor the business case 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 business case 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.
