undertaken to improve a business through
the use computerized information system.

7. System
analysis in
CSE
• A systems analyst is the General
Contractor of computing.
• A Systems Analyst studying a problem
might choose to go with a hardware or
commercial software solution.
• They might choose to write the code
themselves in which case they are also a
Software Engineer.
• They might be responsible for
implementing their plan, in which case
they are a Project Engineer.
8. Real life use
Whenever you have a complex
problem to solve, particularly
when the problem involves
multiple technologies or
disciplines. Systems analysis
provides tools for decomposing
complex problems into simpler
ones and synthesizing a
solution.
A variety of businesses use
system analysis, including
healthcare, manufacturing, and
retail. For example, hospitals
use system analysis to help
them plan and track patient
care, while manufacturers use it
to improve production processes
The purpose of Systems
Analysis is to understand a
system. That is to say it
analyses the components of the
system and their inter-
relationships, which enables us
to understand the structure and
behavior of the system.
System Analysis is important
because it provides an avenue
for solutions in the system
through the various tasks
involved in doing the analysis.
