Systems Analysis and Design

Put SAD into action!

You can't truly understand Systems Analysis and Design (SAD) by only reading about it; you have to do it. In Systems Analysis and Design, Third Edition, Dennis, Wixom, and Roth offer a hands-on approach to actually doing SAD. Building on their experience as professional systems analysts and award-winning teachers, these three authors capture the experience of actually developing and analyzing systems. They focus on the core set of skills that all analysts must possess--from gathering requirements and modeling business needs, to creating blueprints for how the system should be built.

Features
* New and expanded coverage, including expanded coverage of functional and nonfunctional requirements; new event-action lists; a new extended example of process modeling and data modeling; expanded discussion of the use and interpretation of the weighted alternative matrix as well as RFPs, RFI, and RFQs; a new emphasis on the Migration Plan; and new coverage of business contingency planning during implementation.
* Focus on doing SAD. After presenting the how and what of each major technique, the text guides you through practice problems and invites you to use the technique in a project.
* Project-based approach. Topics are presented in the order in which an analyst would encounter them in a typical project.
* Real-life examples include a running case, which serves as a template that you can apply to your own work, and Concepts in Action examples that describe how real companies succeeded (and failed) in performing SAD activities.
* Object-oriented concepts and techniques are included throughout the book, and a final chapter focuses on the major elements of UML. Coverage is updated to reflect the innovations of UML Version 2.0.
