Information Technology - The Analysis Phase: defining information needs


The Analysis Phase: defining information needs

The process of analysing a computer system starts with a broad look at the
system which is then broken down into smaller parts. Each of the smaller
parts can then be broken down into even smaller parts and so on. This
approach enables a complete analysis to occur, without the initial task
appearing to be a task so large as to be unable to be completed.

The purpose of the analysis phase of the system development life cycle is
to document what the current system does, and highlight the strengths and
deficiencies in it.

In the analysis of the system, the following should occur:

* identification and evaluation of sources of information

* identification and description of the types of information needed to
analyse the system

* identification and description of the types of information needed to
design the system

* information flow and needs documented using system modeling tools

* identification and description of problem areas in the current system,
which are grouped and become the basis for the development of the new
system.
