Abstract
CMMI (Capability Maturity Model Integration) has been used as a model or method to improve software development processes in a number of software development sites, which defines the maturity level as a guide to measure the ability of an organization's software development. In the activities to achieve the maturity level, defining and implementing a CMMI-compliant process are required; it is essential to promote mutual cooperation between SEPG with knowledge of the CMMI model and developers with knowledge of actual development processes. This paper describes the "process design method" invented and exercised by the author through the CMMI activities, which is an approach to effectively create standard process procedures by utilizing existing assets through joint efforts by both SEPG and on-site development members.
