Implementing a new information system
a. Non-computer organisational factors to consider
The implementation of a computer system is likely to affect an organization in a number of
ways:-
o Organisational structure change;
o Will the past history and culture of the organization be affected;
o External environment factors such as the use of computers at home; Possible
change in organisational levels, currently flatter;
o Significant changes in the current tasks and the decisions that are taken;
o Are management supportive of the changes that will occur as a result of the new
system;
o Age, skills, computer literacy of the workforce involved.As
we question ourselves. The above factors are to be considered.
b. Relationship between information systems and organisational politics
Information systems can determine what information, its content, its timing and action
required within an organization, leaving little latitude for individual discretion. By so doing
IS helps to determine the access of specific subgroups and interests in the organization to
information which is a key resource. Thus the balance of political power that already exists
may change causing unrest in the organization.
