Essentials of System Analysis and Design (3rd Edition)

Written primarily for undergraduates Systems Analysis & Design courses in CIS and MIS programs. It is designed for courses seeking a streamlined approach to the course due to course duration, lab assignments, or special projects. The text reflects current changes in systems analysis and design. The move to structured analysis and design in the late 1970s was considered to be a revolution in how systems development was conducted. We are undergoing another revolution in systems development now, as we move away from complex, plan-driven development to new approaches called "Agile Methodologies." Although the best known Agile Methodology is eXtreme Programming, there are many other approaches. More and more systems development involves the use of packages in combination with legacy applications and new modules. Coverage of the make versus buy decision and of the multiple sources of software and software components has been moved forward in the book to highlight the salience of these topics.</P>
