“Data is only potential information; information is potential knowledge; and knowledge is potential competitive advantage if it is used in a creative, flexible, and above all, accurate way.”
Adrian M (1990) Let’s Get Serious. Focus News. Winter.
The System is composed of a number of Sub-systems (i.e. the Internal Environment).
The System has a Boundary(which separates it from other Systems) and a ‘unique’ Identity(which distinguishes it from similar Systems).
The System ‘exists’ within other Systems (i.e. the External Environment).
In addition to all of the things that the ‘Systems in Context’ diagram depicts, this diagram also;
Names the Elements which are components of each Sub-System.
Shows the connections & interactions;
between this System & other Systems (i.e. in the External Environment).
between the Elements of each Sub-System (i.e. in the Internal Environment).
Viewing Customer Services as the System.
The ‘Elements’ are Processes which were ‘hidden’ on the ‘High-level Systems Diagram’.
Processes require ‘Inputs’ (i.e. data) and produce ‘Outputs’ (i.e. information).
NB. It is only at this level of detail that we know enough to suggest where IT might be employed effectively?
