Systems Analysis is, as the name states, the analysis of systems!

The systems that we are talking about are the systems within organisations and businesses - systems of communication, financial systems, manufacturing systems, etc. - basically the systems that make the organisation or business work.

A person who analyses systems is known as a Systems Analyst.

Often systems analysts are employed by organisations of businesses to help them improve their systems and so become more efficient, and for businesses, more profitable.

A systems analyst would generally perform the following steps in the order shown...

Research
 Collecting information about the present system works

Analysis
 Examining out how the present system works and identifying problems with it

Design
 Coming up with a new system that will fix the present systems problems

Production
 Creating the new system from the design


Testing
 Checking if the newly created system works as expected

Documentation
 Creating documents that describe how to use the new systems, and how it works

Implementation
 Replacing the present system with the new system

Evaluation
Checking that the new system meets all expectations
