This book explores the domain of software maintenance management and provides road maps for improving software maintenance organizations. It describes full maintenance maturity models organized by levels 1, 2, and 3, which allow for benchmarking and continuous improvement paths. Goals for each key practice area are also provided, and the model presented is fully aligned with the architecture and framework of software development maturity models of CMMI and ISO 15504. It is complete with case studies, figures, tables, and graphs.

Klappentext
The only authoritative reference to provide a management perspective of software maintenance
Software maintenance accounts for 6090% of software life-cycle costs, and unfortunately, very little attention is given to software maintenance education, training, and research. Now, two experts in the field explain how understanding software maintenance, implementing best practices, and improving its processes can help software managers to dramatically cut costs.
Software Maintenance Management explores the domain of software maintenance management and provides road maps for improving software maintenance organizations. It describes full maintenance maturity models organized by levels 1, 2, and 3, which allow for benchmarking and continuous improvement paths. Goals for each key practice area are also provided, and the model presented is fully aligned with the architecture and framework of software development maturity models of CMMI and ISO 15504.
Complete with case studies, figures, tables, and graphs, Software Maintenance Management fills the need for a comprehensive and authoritative reference on the subject for maintenance managers, software managers, systems analysts, quality managers, and quality analysts. It alsoserves as a valuable textbook for advanced undergraduate and graduate courses in softwareengineering, software maintenance, software process improvement, and software benchmarking.
