System Efficiency and Effectiveness
The performance of the system can be measured by two factors,
viz., the efficiency and the effectiveness. The efficiency indicates the manner
in which the inputs are used by the system. Being efficient means the system uses
inputs in a `right' way. If the input-output ratio is adverse, we say that the
system is inefficient though it produces the desired output.
The effectiveness is the measure for deciding whether the
system provides the desired output or not.
Being effective means producing the right output in terms of quantity and
quality. When the system is ineffective, the system is out of control and it
needs a major correction.
A system has to be effective and efficient for the highest
utility to the user of the system.
Broadly speaking, the effectiveness is a measure of the goodness of the
output, while the efficiency is a measure of the productivity, i.e., the measure
of the output against the input.
