Once the new system has been implemented and is in full use, the system
should be evaluated (this means that we take a long, critical look at it).
The purpose of an evaluation is to assess the system to see if it does what it was supposed to do, that it is working well, and that everyone is happy with it.

What Does an
Evaluation Look For?
When the systems analyst evaluates the new system, the following
questions will be asked:
Is the system efficient?
Is the system efficient?
Is the system easy to use?
Are all of the system's users able to use the system easily and
effectively?
Can new staff understand and use the system with minimal training?
Can new staff understand and use the system with minimal training?
Is the system suitable for that particular business / organisation?
Does the system actually meet the needs of the business / organisation?

How is a System Evaluated?
The systems analyst will use a number of techniques to evaluate the
system...
Check against the Requirements Specification
If you remember, earlier on in the Systems Analysis, the old system was
analysed,
and a checklist
of targets was drawn up for the new system.
This list was called the Requirements Specification.
The systems analyst will use this document to check the new system. Going through the requirements one-by-one the analyst will check if they have been met.

Check the Users'
Responses
It is essential to get feedback from the users
of the system...
- Do they like it?
- Does it make their work easier?
- What, if anything, could be improved?
The systems analyst can get this feedback in the same way they collected
information about the original
system.
What Happens Next?
The outcome of the evaluation will be to identify any limitations
or problems
with the new system.
The system analyst will then need to begin the task of system analysis from the beginning, but this time analysing the new system, and then designing, testing and implementing improvements.
Thus the whole process repeats.
