ABSTRACT
The success of organizational information systems (IS) depends largely upon
A
effective planning for those information systems. comprehensive IS plan should
provide a coordinated approach to strategic business goals, organizational information
requirements, and an overall measure of performance.
Acknowledging the importance of comprehensive planning in the process of
managing the organization's information resource, a collection ofmethodologies has been
accumulated, to serve in carrying out the IS planning effort. However, a managerial
problem that often arises is how to make best use ofcurrent planning methodologies. The
purpose of this thesis is to survey the existing methodologies, establish a framework for
analyzing the IS planning methodologies, and examine some of their advantages and
limitations.
