When deciding what type of network was required for a new information
system 3RRR management consulted staff extensively. View a video in which
Kath Letch, Station Manager, discusses this process.
In order to perform an analysis of a system, the first step must be to
identify the sources of information that will provide views on the running
of the current system. This will involve the users of the information the
system produces, users of the actual system and people who support the
Each of the groups will provide information that contributes to the
construction of an overall picture of the running of the system. In each of
the broad groups identified above, there will be different categories or
subgroups within it. It is important that input is received from all of
these parties so that a well-balanced overall view of the system can be
Image. In order to perform an analysis of a system a number of people must be
consulted: users of the information the system produces, users of the
actual system and people who support the system.
When performing an analysis of the current system, the views of the users
of the system are paramount in successfully recognising the strengths and
identifying weaknesses present. The first task of the analyst will be to
identify who they need to consult to find out about the current system. In
doing this, they will need to identify the following users of the system:
those who provide data, those who input data, those manipulate the data and
those who receive data. As well as these groups, they will need to identify
the group above this - those who own or run the organisation - for they
will also have ideas as to what the system is doing, what it can be doing
or what it should be doing. Although you would imagine the discussion with
the users of the system would uncover this information, it is surprising
just how often management's idea of what is happening is different to that
of the users of the system.
