The document outlines an information system plan, discussing approaches to organizing the planning effort, the content and maintenance of a master plan, and models for information system growth. It describes a three stage planning process involving strategic planning, organizational information requirements analysis, and resource allocation. The master plan would include both long-range and short-range components as well as details on hardware, software, applications, and financial resources.

2. Planning for Information System
• The complexity of the information resources
environment suggests that planning is vital to
success.
• The plan describes the structure and content of
the information system and how it is to be
developed.
• The organization’s strategic plan should be the

3. Approaches to organizing and supervising the
information system planning effort
• Planning staff within information systems
functions (planning specialists)
• Ad hoc planning groups within information

• Planning group with representatives from
various functions
Management Information System 3

4. Review of plan

committee which comprises of executives from
major functional areas and is executives.
• The committee also periodically reviews progress
against the plan.
• The master plan is integrated in the
organizational plan by top management after

5. Content of Master development plan/ Information
System plan/ Information Resource plan
• The master plan has two components:- a long-range
plan and a short-range plan. The long-range plan
provides general guidelines for direction and the short-
range plan provides a basis for specific accountability
as to operational and financial performance. It consists
of the following subheadings:-
– Information system goals, objectives, and architecture
– Inventory of current capabilities
– Forecast of developments against the plan
– The specific plan
Management Information System 5

6. Master plan
Information system goals, Objectives, and
architecture
– Organizational goals, objectives, and strategies
– External environment (industry, government
regulations, customers, and suppliers)
– Internal organizational constraints such as
management philosophy
– Assumptions about business risks and potential
consequences
– Overall goals, objectives, and strategy for the
information system

Management Information System 6

7. Master plan
• Current capabilities
– Inventory of
• Hardware
• Software (System software, DBMS, etc)
• Application systems (classified on the basis of functional systems,
organizational strategy, maintenance need)
– Analysis of
• Expense
• Hardware utilization
• Software utilization
• Personnel utilization (further classification such as job, skill,
functional area)
– Status of projects in progress
– Assessment of strengths and weaknesses
Management Information System 7

8. Master plan
• Forecast of developments Affecting plan
– Hardware and software technological availabilities
should be forecasted with expected impact on
existing IS
– Methodology changes should be forecasted
– Environmental developments such as government
regulations, tax laws and competitors affecting IS
should be stated
Management Information System 8

9. Master plan
• Specific plan
– Hardware acquisition schedule
– Purchased software schedule
• System Software
• Applications software
– Application development schedule
– Software maintenance and conversion schedule
– Personnel resources required and schedule of hiring
and training
– Financial resources required by object of expenditure

10. Maintenance of master plan
• IS plan requires updation
– Changing organizational setup

11. Information system growth models
• The NOLAN stage model
The organization must go through each stage of growth before it can progress to the next
one, thus giving an insight to planning regarding the stage of an IS
Stages of Information system growth

13. NOLAN six stage model
Application portfolio complete and matches organizational
objectives
VI
Slack due to focus on strategically important systems
V
Use of databases for integration
IV
High controls, planning given importance
III
Greater slack due to encouraged use, integration and lack of
planning
II
Low control. Some slack. No planning
I
Level of control or slack

15. NOLAN alternative model
Due to technological changes the growth curve
shifts as follows

16. Assumptions of NOLAN model
• Organizational learning
• Stages cannot be skipped
• Other than the natural process, these
processes can be planned, coordinated, and
managed to move through the stages
effectively and efficiently

17. Advantages and disadvantages of
NOLAN model
• Advantages
– Evolutionist model as it focuses on development
• Disadvantages
– Lack of specificity as it does not define the
mechanism for change

18. Three stage model of the planning process
• It clarifies the generic planning activities, the order of
activities, and the alternative techniques and methodologies
that apply

20. Strategic fit
• Each organization has a culture which
reinforces values, norms, and beliefs about
the organization. Goals, objectives, and
strategy for information systems should fit
with the culture in order to avoid high
resistance and high risk of failure.

21. Strategy Set Transformation
• Explicate the organization’s strategy set
– Delineate the organization structure for users
– Identify goals of claimants
– Identify organizational goals and strategies for each claimant group
• Validate the organizational goals from management
• Transform organizational strategy set into the information
system strategy set
– Identify IS objectives for each organizational strategy
– Identify IS constraints from organizational strategy
– Identify IS design strategy based on organizational attributes

22. Analysis of Organizational information requirements
• Information requirements are required at the
organizational level for information system
planning, identifying applications, and
planning an information architecture.
• More detailed information requirements are
required for detailed design of applications.
