How to Build a Business Case for Government AI
Building a defensible government AI business case: baseline evidence, public value, total cost, capability investment and realistic benefit timing.
How Should a Government Department Build a Business Case for AI?
A credible case starts from a measured baseline and states the public value in service terms — faster resolution, wider coverage, fewer errors, better targeting. Cost must include capability building, data work, governance and support, not licence fees alone. Benefits should be phased and evidenced, not projected as immediate savings.
Key Takeaways
No baseline means no provable benefit.
Public value is the primary case; cost saving is secondary.
Capability and data work dominate real cost.
Phase benefits honestly across years.
Practical Framework
Business Case Structure
Baseline
Current volumes, turnaround, error rates and cost to serve.
Value
Service, quality, coverage, compliance and officer-time outcomes.
Cost
Licences, integration, data, capability, governance and support.
Evidence Plan
How each claimed benefit will be measured and when.
What Government Leaders Should Do Next
- Measure the baseline before writing the case.
- Include capability cost as a named line item.
- Phase benefits over realistic timelines.
- Define the evidence that will confirm each benefit.
Risks and Common Mistakes
- Vendor-supplied savings figures used unverified.
- Capability and change costs omitted.
- Benefits claimed in year one.
- No measurement plan attached to the case.
What Delay Costs: AI Business Case Government
- Proposals compete on optimism rather than evidence.
- Funded projects cannot demonstrate results.
- Future AI proposals face heightened scepticism.
A business case with no baseline is a forecast nobody can ever be held to — including the people who wrote it.
