Why is the IT Service Catalogue critical for IT Costings?

There are many datasets used in an IT Costings exercise, none as critical as the IT Service Catalogue. While most the attributes of a typical catalogue are not used, it is essential to get the Portfolio of IT Services well defined.

This is so one can align all aspects – such as the SLAs, Operational Risks, Costs and Project Investments – of your Technology estate to a common lexicon to measure its performance.
