System Analysis and Design

by RIFADUL ISLAM

Systems Analysis and Design (SAD) is a broad term for describing
methodologies for developing high quality Information System which
combines Information Technology, people and Data to support
business requirement. The SAD technique is not only limited to IT
systems and can be used to create just about anything, from a family
house to the international space station. But there is no silver bullet
in simplifying the development of computer systems. This principle is
still true today. In other words, there is no single, simple technique
that developers can use to ensure successful Information Technology
(IT) projects. However, there are development methodologies that can
be followed which will greatly assist an IT professional in developing
and enhancing systems. [1] A methodology is essentially a procedure
to get something done. A development methodology can be thought of
as a roadmap. While a roadmap for a traveler will provide the details
from driving from point A to point B, a development methodology will
provide the IT professional with guidelines for taking a system from
conception through implementation and beyond [2]. Before going into
the details of System Analysis and Design we will shortly discuss the
history of it.

The area of SAD has the contribution of different developmental
teams which includes the system analysts who are analyzing how users
interact with technology and businesses function by examining the
inputting and processing of data and the outputting of information
for improving organizational processes. Many improvements involve
better support of users work tasks and business functions through
the use of computerized information systems. So the system analyst
must play the role as a consultant, a supportive expert and an agent
for change.
The Business Analysts focuses on the business issues of the system.
These include identifying the business value that the system will create,
developing ideas and suggestions for how the business processes can be
improved, and designing the new processes and policies in connection
with the systems analyst. This individual will be equipped with the
business experience and good professional training for analyzing
business trends.

Another important role in SAD is the change management analyst
who works on the people and management issues surrounding the
system installation. The roles of this person include ensuring that
adequate documentation and support are available to users, providing
user training on the new system, and developing strategies to overcome
resistance to change. This individual likely will have significant training
and experience in organizational behavior in general and change
management in particular. He or she represents the interests of the
project sponsor and users for whom the system is being designed.
The change management analyst works most actively during the
implementation phase but begins laying the groundwork for change
during the analysis and design phases
