System Integration Business Case
This is a practical guide to building a business case for a system integration project — the justification that weighs the costs, benefits and risks of doing the project, adapted to the realities of integrating multiple systems into a coherent whole.
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 a system integration project it plays the same role, tuned to this kind of work.
Why it matters for a System Integration project
System Integration projects live or die on integrating multiple systems into a coherent whole. 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 system integration projects drift into avoidable delay and cost.
What to include
- Problem or opportunity
- Options considered
- Costs and benefits
- Financial appraisal (ROI/NPV/IRR)
- Recommendation
System Integration-specific considerations
Tailor the business case to the risks that most often derail system integration projects:
- Interface and API complexity
- Data consistency
- Vendor coordination
Example
On a real system integration project, the business case would be shaped by integrating multiple systems into a coherent whole. In particular, it should explicitly account for the project’s biggest risks — interface and API complexity, data consistency, vendor coordination — rather than treating them as afterthoughts.
