Summary

Hay presents a comprehensive overview of the world's best requirements analysis practices, organized into a coherent architectural framework that helps analysts choose the best approach for each project, and execute it successfully. Hay helps current and prospective analysts focus more clearly on their goals: to accurately represent the business's fundamental structures, identify key information processing gaps, and discover which information technologies may best address them. He addresses requirements analysis from two viewpoints: the system development life cycle (the steps required to build and implement a system) and the architecture framework (the perspectives of key players in the development process).
