ITIL has been criticized on several fronts. Although the ITIL covers a number of areas, its main focus is on IT Service Management. ITIL is built around a process-model based view of controlling and managing operations.
Accreditation is governed by the passing of two exams - the Foundation and the Practitioner. This guarantees that all software meets the demands of the business processes. ITIL V3 Application Development PRINCE2 suggests that projects should be broken down into stages and these sub-processes dictate how each individual stage should be controlled.
It incorporates IT Service Management within its Control Objectives for Support and Delivery. Core Practice (CoPr or "copper") calls for limiting Best Practice to areas where there is a business case for it, and in other areas just do the minimum necessary.
This use of the term "Service Management" is how many in the world interpret ITSM, but again, there are other frameworks, and conversely, the entire ITIL library might be seen as IT Service Management in a larger sense.
