INFORMATION
TECHNOLOGY PLANNING
1. It is the organized planning or I.T.
infrastructure and applications portfolios done at various levels of the
organization
2. IT planning is important for end
users for the following reasons:
·
End
users do I.T. planning for their own units
·
End
users must participate in the corporate I.T. planning, hence must understand
the process
·
Corporate
I.T. planning determines how the I.T. infrastructure will look. The future of every unit in an organization
will be impacted by the infrastructure
3. A good I.S. plan has to keep in mind
the internal customers as well as the external customers and vendors. The I.S. has to work closely with the
business side to make sure I.S. is helping the company stay competitive.
4. A strategic information system plan
identifies a set of computer based applications that will help the company
reach its business goals
5. IT planning has similarities and
differences as compared to any business planning e.g. forecasting which part of
planning is predicts the future.
Planning is preparing for the future.
6.1 ISSUES IN IT PLANNING
·
The
basic information systems planning address the four general issues:
·
Aligning
the I.T. plan with the organizational business plan
·
Designing
I.T. architecture for the organization in such a way that users, applications
and
Databases can be integrated and
networked together.
·
Efficiently
allocating information systems development and operational resources among
Competing applications
·
Planning
information systems projects so that they are completed on time and within
budget and include the specified functionalities
6.2 ALIGNMENT OF THE IT PLAN WITH
THE ORGANIZATION PLAN
·
The
first task of I.T. planning is to identify information systems applications
that fit the priorities established by the organization
·
Organizational
strategies and plans are often not available in written form, or they may be
formulated in terms that are not useful for information systems planning. It is often difficult to ascertain the
strategies and goals to which the information systems plan should be aligned.
·
Without
this alignment the information systems plan cannot get and keep long term
organizational support

6.3 DESIGN OF INFORMATION
TECHNOLOGY ARCHITECTURE
Information technology architecture
refers to the overall high-level structure of all information systems in an
organization. This structure consists of
applications for various managerial levels (operational control, management
planning and control and strategic planning) and applications oriented to
various functional-operational activities such as marketing, production and
distribution. Information technology architecture also includes infrastructure
e.g. databases, supporting software and networks needed to connect applications
together. Information architecture for an organization should guide long-range
development as well as allow for responsiveness to diverse, short range
information systems demands.
6.3.1 ALLOCATION OF RESOURCES
Rational, optimal allocation of
information system resources among competing organizational units is
difficult. This is true if the
functional or organizational unit requirements have not been integrated into a
planning framework and establishes completeness and priority. Sometimes
organizational dynamics, such as relative power and aggressiveness are used in
place of rational allocation.
6.3.2 COMPLETION OF PROJECTS ON
TIME AND WITHIN BUDGETS
Few IS projects or applications are
completed on time or within budget.
Often, under the pressure to finish a project on time and/or within
budget certain promised features are omitted.
This reduction in functionality
and/or quality frequently leads to user dissatisfaction with the resultant
system. Missing or inadequate features
must be added later in what is usually called “system maintenance”. Better
project planning could avoid or reduce the impact of such mishaps.
6.4 PROBLEMS WITH IT PLANNING
·
I.T.
planning can be expensive and time-consuming process
·
Research
findings suggest that, although IT planning is desirable, organizations should
be careful not to devote an excessive amount of resources to these efforts e.g.
time, human resources, as it will derail other productive functions in an
organization.
·
Organizations
should beware of pitfall of allowing IT planning to become an end in
itself.
·
To
achieve the potential benefits of IT planning, organizations need to focus
greater effort on actually implementing the plans they develop.
6.5 A FOUR-STAGE MODEL OF IT PLANNING
Below is a basic four-stage model of
I.S. planning
Generic Strategic Information Resource Project
activity IT requirements allocation planning
planning analysis
Most organizations engage in each of
the four stages, but their involvement tends to be sporadic and influenced by
problems as they occur, instead of reflecting a systematic, stage-by-stage
process.
Major IT planning activity Description
Strategic IT planning Establishing
the relationship between the overall
organizational
plan and the IT plan
Information requirements analysis Identifying broad, organizational information
requirements to establish a strategic
information architecture that
can be used to direct specific
application
Resource allocation Allocating
both I.T. application development resources and operational resources
Project planning Developing
a plan that expresses schedules and resource
Requirements for specific
information systems projects
