The amount of time and expense spent debugging, customizing, updating, and maintaining software far outstrips the amount spent buying it. This book provides a simple and straightforward introduction to software maintenance activities that work. It is thefirst book to cover software transition--the process of moving the product from developer to maintainer. Written by one of the world's foremost experts on software maintenance, it draws on real world case studies to explore basic do's and don'ts, IEEE and ISO requirements, organizational issues, and the often sticky issue of metrics. Other topics addressed include object-oriented software and client/server software, corporate education and training programs, creative cost controls, and more.
