The Business Case for Model-Based Software Development

by Ron Lannan


Use of Model-Based Design (MBD) processes for embedded controls software Development has been purported for nearly the last decade to result in cost, quality, and delivery improvements. Initially the business case for MBD was rather vague and qualitative in nature, but more data is now becoming available to support the premise for this development methodology. Many times the implementation of MBD in an organization is bundled with other software process improvements such as CMMI or industry safety standards compliance, so trying to unbundle the contributions from MBD has been problematic. This paper addresses the dominant factors for MBD cost savings and the business benefits that have been realized by companies in various industries engaged in MBD development. It also summarizes some key management best practices and success factors that have helped organizations achieve success in MBD deployment.
