ITIL and CMMI synergies

CMMI has been developed by the Carnegie Mellon University – Software Engineering Institute. It consists of best practices that address the development and maintenance of products and services covering the product life cycle from conception through delivery and maintenance. A product can be an airplane, a digital camera, a drug or a software package available from a commercial retailer. It can also be a Service such as those defined into IT Service Management. CMMI integrates bodies of knowledge that are essential when developing products, but that have been addressed separately i... (more)
