IT Services CMM evolves into (Capability Maturity Model Integration for Services) CMMI-SVC
IT Services CMM (Capability Maturity Model) was a promising holistic approach to maturity assessment and subsequent improvement of IT Service Management. It was based on the Software CMM from Carnegie Mellon University. IT Services CMM V1.0 Release 1 was developed in 2005 by Vrije Universiteit in Holland, CIBIT and Serco and is still freely downloadable. Software CMM itself evolved into CMMI v1.0 in 2000 and in the last few years has evolved further into CMMI v1.2 which includes 3 "Constellations": CMMI-Development, CMMI-Acquisition and CMMI-Service (CMMI-SVC). It is expected that CMMI-SVC which has taken input from IT Services CMM will be released in Q1 2008. Link here to a presentation on CMMI-SVC from Lamri (Mar 2007) and here for a presentation that compares CMMI-SVC with ITIL, ISO 20000 and SPICE (Aug 2007 by Cater-Steel of University of Southern Qureensland).
