Information Technology - The Analysis Phase: identification and
description of the types of information needed to analyse the system

The Analysis Phase: identification and description of the types of
information needed to analyse the system

Having identified the sources of information, the next step the analyst
must take is to establish what information can be gained from them. The
information which can be gained from the manager will be different from the
data entry clerk, which will be different from the customers and so on. The
analyst must decide what information should be obtained from each source
identified.

It is unusual for one user to be the exclusive source of information about
the system. Most aspects of the system will have some degree of overlap -
it may be that significant detail will come mainly from one source, but
there will usually be other users who are also impacted, and information
must be collected from them as well.

As well as identifying who will be capable of supplying what information
in this step, the analyst must also make decisions about the reliability
and suitability of the sources. Information collected must be evaluated for
bias and relevance and given the appropriate weighting in the overall
analysis of the system. For example, while a manager and a data clerk would
both have opinions on the usefulness of the financial reports produced by a
particular system, the manager's opinion would have more weighting, but
conversely, the data clerk's opinion has more significance in areas
relating to the ease of data entry.

Sometimes, the analyst will identify the need for other information in
order to fully analyse the system. In this case, they would need to
document where this information can be obtained. An example of this would
be the need to conform to government privacy regulations with regard to the
release of confidential data on individuals.
