Scope of computerization
When introducing computerization, it is
necessary to review the scope to determine how much of the operations to include in the system. If the scope is too
small, it may be ineffective. If it is too
large, it may be unmanageable.

Cost effectiveness
Reviewing whether the system to be
developed is cost effective is very important as it can result in the success or
failure of the business strategy.
When introducing a system, it is necessary to determine the costs related to
development and operation, and review
whether the benefits will exceed the
costs and whether an effect corresponding to the costs can be achieved.
If there is no prospect for achieving the
desired effect, then computerization itself needs to be reconsidered. Computerization requires regular evaluations
that look into how much efficiency can
be achieved, and how much profits will
increase in order to determine whether
the desired level of cost effectiveness
has been achieved.

Chapter 3
“Computerization planning” is the act of developing and planning an information system designed to streamline operations by putting together a
computerization initiative and a basic policy for computerization based on
the business or enterprise strategy. A “computerization initiative” is an
introductory step which involves analyzing operations prior to defining the
system requirements to produce the big picture for computerization that
will serve as the basic requirements for the system, the scope, the schedule, the budget, etc. Development related to computerization is carried out
in accordance with the company’s system strategy and business model. If
the computerization initiative is flawed, operations may become more
complicated than before or produce unexpected results.
The “basic policy for computerization” is the basic development policy
set forth when computerizing operations. Computerization is implemented
based on elements of the basic policy such as the purpose of development
and the issues to be addressed. The computerization plan is put together in
the final stage of laying out the system.
During the planning stage for computerization, it is necessary to put together a solid computerization plan based on the big picture that includes
the schedule, structure, scope of operations, and cost effectiveness.
The procedure for planning computerization is summarized below.
Review of schedule
The overall development schedule set forth in the computerization plan is
reviewed.
First, an overall development schedule that seeks full computerization by
the time the system becomes necessary is planned. It is based on the business strategy and takes into account factors such as order of construction,
transition from current operations, and education and training.
If too much priority is placed on meeting deadlines and the system development period is cut short, the quality of the system may suffer. Management must make a decision whether to give priority to finishing the system
by the time it becomes necessary, or making sure the system is fully developed even if it results in a delay.
