1. Remember a Business Case drives the project, it does not sit on the shelf; it evolves throughout the project

2. Always overestimate the cost and underestimate the benefits!

3. A Business Case must have measurable & tangible benefits

4. Use cost estimation techniques e.g. three points estimating, producing a weighted average estimated cost i.e. from best (a), worst (b), most likely, which is then used in the formula:

Estimated cost = (+ 4b) / 6

5. Benchmark & validate your estimate of cost & benefits.

6. Get Finance to review and approve the business case

7. Incorporate quick wins to deliver early demonstrable benefits


8. Get stakeholders, preferably sitting on the Steering Committee, to take responsibility for benefits

9. Any change request must add value/benefits to the business case

10. Regularly measure and monitor costs and benefits – incorporate in management information system
