描述
This book is a must-have for all IT professionals facing software development problems on a daily basis. If you are a systems analyst or requirements engineer it will provide an essential, practical guide from the task of identifying the problem to making the descriptions needed to resolve it.It will help decompose complex problems into simpler subproblems and see how the subproblems fit together; and build up a repertoire of simple, clear and easily applicable problem classes which you can access and reuse, drawing on the experience associated with each class. numerous real-world example problems are analyzed, giving you insight into how to recognize and structure your own problems in practice; a mixture of large and small problems is presented, showing the stripped down essence of problem classes and discussing different aspects of each problem; problem frames are independent of any particular development method, so they can be easily applied in your own situation; and appendices summarizing the descriptive languages and notations; plus a glossary of terminology.
