3. Investigation

The management have taken the decision to proceed with the project.

The next stage is called the 'Investigation and Analysis' phase.

First you investigate how the old system works and the problem(s) it is causing and then you analyse it to see how you can solve these problems.

During the investigation, you would use a variety of techniques to find out about how the current system works in great detail:

- Questionnaires

- Interviews

- Observing people doing their job

- Following a paper trail through the system - finding out what happens to a document at each stage.
