CMMI RAMS Extension Based on CENELEC Railway Standard

摘要

Railway systems are also dependable systems and, considering their importance, it is vital to assure the application of adequate design techniques. So, this work presents a RAMS (Reliability, Availability, Maintainability and Safety) extension for CMMI SE-SW version 1.1 "Capability Maturity Model~® Integration" developed by SEI (Software Engineering Institute), based on CENELEC 50126, 50128 and 50129 standards developed to normalize RAMS aspects of railway control systems in European Community. This extension is based on the inclusion of four new Process Areas into the CMMI SE-SW, increasing its actual number from 22 to 26, without changes in the CMMI model basic structure. The objective of this extension is to obtain a support tool for design process applicable to enterprises that develop railway systems and are adopting CMMI or migrating from other CMM models.
