All assumptions used to determine, both quantitative and qualitative, costs and benefits should be clearly documented. This would include general assumptions as well as assumptions specific to each alternative. Any assumptions used to forecast the status quo, develop the public sector comparator, and establish the P3 alternative should be well documented. These assumptions will be re-visited as the project moves through the various stages of implementation and may be changed or removed.
Checklist for Cost/Benefit Analysis Section
1. Has a Public Sector Comparator been included for comparative purposes?
2. Are assumptions applied equally across alternatives?
3. Has the discount rate been identified and consistently applied to each alternative?
4. Has an inflation factor been used fairly and consistently across each alternative?
