This is a substantially new and different edition of Systems Analysis and Design. We hope that the new materials bring it up to date and that we’ve kept the best of the old. It has been written for people studying systems analysis and design or who are already working in systems teams. People who are involved in the development of new systems or the development of new systems analysts, or both, have written it. It is intended to be a practical book, easy to read and easy to use. It follows the same structure as the previous edition and has new and updated material in it. There are more case studies and exercises too and we’ve crossreferenced the topics to the ISEB syllabus in systems analysis and design.
