Preface
A system is a ubiquitous phenomenon. From early learning activities to the spec-
tacular education and practices, one has to deal with systems. The subject of sys-
tems analysis and design has been taught to various streams, courses, and levels.
There are many careers that require a fundamental knowledge of the subject. To
name a few, software engineer, tester, systems analyst, programmer, designer,
knowledge engineer, data scientists, and Big Data practitioner are the roles where
systems analysis and design knowledge is a must. Rather, it can be said that in all
aspects of the business, somewhere the subject is useful.
As a teacher of the systems analysis and design subject at the postgraduate level,
I have observed following important things:
• The systems analysis and design subject is very lengthy and descriptive in nature,
which confuse students about the applicability of answers.
• Quick revision from the reference book is challenging.
• Supporting materials such as diagrams, case studies, and objective as well as
subjective questions with answers are also not available in a single book.
The book Essence of Systems Analysis and Design– A Workbook Approach iden-
ties essential topics and presents cruxes of the core topics, which are mandatory
and trivial. Further, the book encompasses questions and answers based on the
selected topics. The main objective of the book is to provide quick and essential
knowledge for the subject with the help of summary and solved questions/case stud-
ies without going into detail discussion of the content. This book will be much help-
ful for the students as a supplementary text-/workbook and to the noncomputer
professionals, who deal with the systems analysis and design as part of their busi-
ness. The problem-solving approach of the book enables learners, academicians,
practitioners, and researchers to gain much practical knowledge of the subject, with-
out going into lengthy discussions. Besides quick understanding of the core topics
via practical problem solving, this book also provides guidance on how to document
answers and cases related to the subject.
Though the book is conceived as the supplementary text-/workbook, the topics
are selected and arranged in such a way that it can provide complete and sufcient
