• Maturity of information systems through CMMI and ITIL

Driss Houari*, Pr. Ounsa Roudiès


There are many quality standards and maturity models that can help an organization improve its processes. However most of these standards are specialized in a single field of activity. So, in order to cover all of their activities, companies must adopt more than one standard.

In this article, we present two standards that are most used in the software development industry: CMMI and ITIL by specifying the specificities of each one, the common points and how they can live together in the information system of an organization. These standards have been initially designed by state agencies, the first in the United States by the DoD and the second in Britain by the CCTA.
