Modern Systems Analysis and Design

The third edition of Modern Systems Analysis and Design investigates the very latest of systems analysis and design. Rather than looking strictly at the technological aspects, Hoffer, George and Valacich focus on the business perspective and the human, organizational and technical skills an information systems professional needs to be successful. Chapter topics cover foundations for systems development, making the business case, analysis, design, implementation and maintenance, and advanced analysis and design methods. For information systems professionals.

• Increased focus on "make versus buy" and systems integration. More and more systems development involves the use of packages in combination with legacy applications and new modules. Chapter 11 shows how companies deal with these issues.
• Coverage of Internet-based systems. The authors have redesigned the distributed systems design chapter (now Chapter 16) to also address Internet-based application design topics not covered in the other chapters: They cover Internet application design standards, how to maintain site consistency, security issues, and data warehousing, among other topics.
• Expanded coverage of process modeling techniques. Chapter 8 now includes an introduction to business process modeling and functional hierarchy modeling as alternatives to data flow diagramming. These three process-modeling techniques are compared so you know when to use each in practice.
• Unlike other SAD texts, Modern Systems Analysis and Design has continually offered strong coverage of RAD — an important element in systems design.
