EXPERIMENTATION
In systems analysis, experimentation is the
process of determining the results of a proposed course of action
or program by conducting an experiment on a smaller scale in
which the course of action is applied to a sample drawn from the
future target group. An example would be a test of a new health
policy in a restricted region instead of the whole country, or a
test on a randomly selected sample of the population. The
results are best when the experiment is controlled--i.e., when
the test and control groups are chosen before program
implementation in such a way that they are as similar as
possible. In this way, any differences that are observed during
the experiment can be ascribed to the program. Experimentation is
used whenever current knowledge and understanding of factors such
as social attitudes and group preferences are not sufficient to
provide dependable model-based predictions.
