Analysis & Design of Information Systems
Notes commercially obtainable. The objective of these planning techniques is to explain an organization-
wide way for a firm’s information systems. This involves recognizing key elements on which
applications are based and are built. It may also comprise illustrating the interrelation of these
elements and possibly documenting the present position of the organization’s information
requirements or outlining future plans. Three broadly used strategies to planning information
systems are Business Systems Planning (BSP) method; Nolan, Norton & Co.’s computer
architecture strategic planning method; and the critical success factors method.
The BSP approach, which is considered as the most extensively used planning methods,
concentrates on recognition of the data essential to run an organization. Nolan, Norton & Co.’s
computer architecture strategic planning method associates an organization’s present potentials
with its future requirements. This method highlights development of a strong technical
infrastructure, or basis, to support the applications. Critical success factors method asks for
identifying areas that are key to an organization’s endurance and to make sure that these elements
are included into the organization’s information systems.
An organization’s corporate work should be reflected all through the grounding and assessment
of its information system project requests. Information systems planning needs a vision-a view
of the impact that information systems have on an organization’s long-term corporate success,
tactically and operationally. Having a vision is necessary, but it must also be conversed if the
organization’s personnel and other resources are to be productively mobilized to put up and
preserve a viable information systems plan.
ISP fundamentally entails:
Identification of the stage of IS in the organization.
Identification of the applications of organizational ISs.
Assessment of each of these applications, depending on established evaluation criteria.
Establishing a main concern ranking for these application.
Identifying the ‘optimum’ architecture of IS for serving the top precedence applications.
!
Caution The plan of an organization’s information systems must consider the firm’s existing
systems, in addition to its future needs.
