- major utility company working with a medium sized outsourcer, moving from time and materials to fixed priced contracts for development projects. The risk premium varied between 20% and 35% to transfer from a T&M to fixed price. 20% was the bottom end of what the supplier was prepared to accept in exchange for carrying the risk, 35% was generally the top end of what the customer was prepared to pay.
- most public sector IT projects carry between 40% and 100% of project costs in the form of risk (i.e. the actual cost will be 40%-100% more than the initial business case suggests). I've been involved in quite a few negotiations to try to fix the risk premium in public sector deals - there's a certain amount of horse-trading, but in my experience it was rarely less than 15% and never more than 30%.
... that second example may also, in part, explain why so many public sector IT projects go over budget....;-)
