Preface
Purpose
As the title implies, The Information System Consultant’s Handbook: Systems
Analysis and Design, was written for professional systems analysts, system
designers, and information system consultants.
The premise is simple. If you are an information system professional,
you often work with existing documentation and are frequently assigned to
a new system development project in midstream, after considerable work
has already been done. In both cases you are likely to encounter unfamiliar
documentation, tools, techniques, and methodologies. The schedule is
(always) tight, so you must quickly get “up to speed” and begin contribut-
ing. This book is written to help you quickly get up to speed.
Assumed background
The Information System Consultant’s Handbook: Systems Analysis and Design
assumes that you have a firm grasp of basic information processing technol-
ogy and that you have had some experience analyzing and designing infor-
mation systems. Consequently, you understand the underlying principles.
The material contained in this book builds on those principles.
