Publisher's Synopsis
This textbook on SSADM Version 4 covers the analysis and design of information systems from feasibility study to physical design. A standard range of techniques is applied progressively to transform raw user requirements into a detailed system specification taking the form of a set of (largely diagram based) products or models.;The presentation of SSADM Version 4 in the book reflects the way in which it is used, and closely follows the development of a comprehensive central case study. Techniques are introduced as and when required, and subsequently expanded or adapted as products are refined in later steps.;The text closely follows that of SSADM itself with a chapter for each stage in the project life cycle. each chapter is further divided into sections dealing with individual project steps. At the end of each section a second case study is used as the basis for exercises in which readers develop a library system specification in parallel with the main text. A suggested solution is provided in a lecturers supplement. When SSADM Version 4 requires the use of techniques outside the method, eg information gathering and cost benefit analysis, the book briefly outlines suitable methods and gives references for further reading.;This text assumes no familiarity with Version 3. A fully-worked, substantial case study establishes the proper application of the method and Version 4 techniques and products are described in context, enhancing the understanding of their purpose and interdependency. A further case-study is used as the basis for exercises.;It is suitable for students on HNC/D courses in business computing/computing science; information systems design degree and MSc courses; students specializing in information systems, particularly project work, and students taking the BCS Certification of Proficiency in SSADM.
