Ranking Project
Options IS implementation can be accomplished by comparison of income
corresponding to each of them. In particular, for assessing recovery of
investments in various projects for the introduction of IS may be employed
known methods that take into account the change in the value of money in time,
among which we can mention:
Present Value Index – PVI
PVI = TPV/II
where PVI - index
reduced costs; TPV - total present value of annual cash flows (Total PV of
Annual Cash
Flows; II - initial
investment (Initial Investment)
Net Present Value - NPV
NPV = PVA - II
where PVI - index
reduced costs; TPV - total present value of annual cash flows (Total PV of
Annual Cash
Flows); II -
initial investment (Initial Investment)
To evaluate the
effectiveness of the implementation of an integrated information system is very
important to analyze changes in the parameters "time - the cost -
quality" in each business process. This analysis considered the first
"strategic" business processes as the most important from the point
of view of an external client. Then,
secondary and subsidiary.
Process variable "time"
Each course
examines changes cost time t for its implementation in connection with the
introduction of IS. Typically, less time spent to perform certain procedures
process and , accordingly, the whole process. When you perform any procedures
reduces the time and how much it is reduced depends on the version of the draft
IS. For example, when the structure of IMS in supporting the process of
logistics enterprises , the mechanism Jast - In - Time significantly reduces
the supply over IS , task-oriented functional units.
Process variable "costs"
With the
introduction of IS should be reducing the cost of resources for the
implementation of the process. In particular, this may be due to reduction in
the number of employees. If the introduction of IS was not able to reduce the
effort required to implement the process, it must be doubts about the
effectiveness of the project.
The parameter of
the " quality "
At this parameter
can also be judged on the effectiveness of the implementation of IS. If as a result
of the implementation of IS, the structure of which, for example , is enabled
for Total Quality Management, is bringing the quality of the implementation
procedures of the process in accordance with standards such as eg ISO standards
and , most importantly, there is an opportunity to bring the quality of the
product of this process in compliance with the standards defined by the
requirements of the customers and standards of ISO, it is possible to judge the
effectiveness of the project in question , taking into account the following.
Software TQM system allows them to adapt quickly to changes caused primarily by
changes in customer requirements and the development of new technologies. This,
in turn, provides the appropriate level of sales and earnings. By correlating
potentially possible level of income derived from the sale of the finished
product of the process , the cost of the project implementation of IS, you can
rank the options and choose the projects satisfying certain criteria.
Each of the
projects under consideration can have its advantages and disadvantages. A final
decision on the choice of the project are taken by qualified experts.
The proposed
approach to evaluating the effectiveness of the project IS obviously needs to
develop and is not unique. Of course, the experts will be used and the criteria
for such assessments, such as the reliability of the system, the quality of
information, and others.
