Alan Dennis' 5th Edition of Systems Analysis and Design continues to build upon previous issues with it hands-on approach to systems analysis and design with an even more in-depth focus on the core set of skills that all analysts must possess. Dennis continues to capture the experience of developing and analyzing systems in a way that readers can understand and apply and develop a rich foundation of skills as a systems analyst.
