This book is designed for professionals and students in software engineering or information technology who are interested in understanding the dynamics of software development in order to assess and optimize their own process strategies. It explains how simulation of interrelated technical and social factors can provide a means for organizations to vastly improve their processes. It is structured for readers to approach the subject from different perspectives, and includes descriptive summaries of the best research and applications.

FEEDBACK SYSTEMS CONCEPTS APPLIED TO THE SOFTWARE PROCESS 11 processes of communication and control (especially the comparison of these processes in biological and artificial systems) [Weiner 1961]. Cybernetic principles are relevant to many types of systems including moving vehicles (ground, air, water, or space), biological systems, individuals, groups of individuals, and species. We are all familiar with internal real-time control processes, such as when driving down a road. We constantly

increases, so does the predictive power of the organizational models. Highly mature organizations can test their improved processes via simulation rather than through costly trial and error in the field. The distinction between open and closed feedback systems described in Section 1.3 typifies the difference between an ad-hoc CMM Level 1 organization and higher maturity organizations in which past process performance data is used to control the current process. The essence of CMM levels 4 and 5
