System Analysis and Design
Systems Analysis and Design is an active
field in which analysts repetitively learn new approaches and different
techniques for building the system more effectively and efficiently. The
primary objective of systems analysis and design is to improve organizational
systems.
Systems
development is systematic process which includes phases such as:
(1) planning,
(2) analysis,
(3) design,
(4) deployment,
and
(5) maintenance.
We will
primarily focus on –
1. Systems
analysis
2. Systems
design
1. Systems Analysis
It is a
process of collecting and interpreting facts, identifying the problems, and
decomposition of a system into its components.
System
analysis is conducted for the purpose of studying a system or its parts in
order to identify its objectives. It is a problem-solving technique that
improves the system and ensures that all the components of the system work
efficiently to accomplish their purpose.
Analysis
specifies what the system should do.
2. Systems Design
It is a
process of planning a new business system or replacing an existing system by
defining its components or modules to satisfy the specific requirements. Before
planning, you need to understand the old system thoroughly and determine how
computers can best be used in order to operate efficiently.
System
Design focuses on how to accomplish the objective of the system.
