P1 Outline the principles of systems analysis
Organisations are required to keep developing new systems because of
different reasons;
The need for growth – expansion to national or international places
Increasing Productivity – altering automation, using robots
Legal Requirements – New restrictions made by the government
What is a development life cycle?
This is a cycle that you follow so that you do all the required things like
defining what you’re making, users needs and then designing and testing it.
Why is it used?
Its used to follow different steps that are required
Its needed so that the system is designed before being made
Design, Implementation, Testing
Following stages to complete it will make it more effective
<Explain reasons why an organisation would develop new systems>

places whether that’s national or international. Increasing productivity is also
another key factor simply because once a company hits a certain milestone they

and figure out their requirements for the Analysis stage. Once that has been
done the designing can start, Implementation; this is important to know where
the system is built. Testing is the most important to make sure the system
