PREFACE

PURPOSE OF THIS BOOK
Systems Analysis and Design (SAD) is an exciting, active field in which analysts continually learn new techniques and approaches to develop systems more effectively and efficiently. However there is a core set of skills that all analysts need to know—no matter what approach or methodology is used. All information systems projects move through the fourphases of planning, analysis, design, and implementation; all projects require analysts to gather requirements, model the business needs, and create blueprints for how the system should be built; and all projects require an understanding of organizational behavior concepts like change management and team building. Today, the cost of developing modern software is composed primarily of the costassociated with the developers themselves and not the computers. As such, object-oriented approaches to developing information systems hold much promise in controlling these costs. Today, the most exciting change to systems analysis and design is the move to objectoriented techniques, which view a system as a collection of self-contained objects that have both data and processes. This change has beenaccelerated through the creation of the Unified Modeling Language (UML). UML provides a common vocabulary of object-oriented terms and diagramming techniques that is rich enough to model any systems development project from analysis through implementation. This book captures the dynamic aspects of the field by keeping students focused on doing SAD while presenting the core set of skills that we feelevery systems analyst needs to know today and in the future. This book builds on our professional experience as systems analysts and on our experience in teaching SAD in the classroom. This book will be of particular interest to instructors who have students do a major project as part of their course. Each chapter describes one part of the process, provides clear explanations on how to do it,...
