For courses in structured systems analysis and design.
Developing advanced system analysts
Prioritizing the practical over the technical, Modern Systems Analysis and Design presents the concepts, skills, methodologies, techniques, tools, and perspectives essential for systems analysts to develop information systems. The authors assume students have taken an introductory course on computer systems and have experience designing programs in at least one programming language. By drawing on the systems development life cycle, the authors provide a conceptual and systematic framework while progressing through topics logically. The 9th edition has been completely revised to adapt to the changing environment for systems development, with a renewed focus on agile methodologies.
