Unit 11: Implementation and Assessment of OD

Factors influencing choice of an OD intervention to fit the best in the situation for implementation? Notes
Selection of an OD intervention is influenced by the following three factors:
(a) Applicability
(b) Feasibility

(c) Acceptability

Applicability

Applicability means the potential of a given intervention to yield desired results. This is possible
when an intervention is capable enough to address the real problem and holds good promise of
solving it. One way to ascertain applicability of an intervention is to examine the likely positive
and negative consequences associated with it. What follows from above is the need for evaluating
one’s client system with great care and concern before actually introducing any intervention.

Feasibility

Feasibility means the suitability of an intervention to suit to the client system.

Notes In other words, one needs to evaluate whether an intervention can actually be
effectively introduced in a given type of client system.

Acceptability

Whatever applicability and feasibility an intervention carries has no use unless it is acceptable
to the client system. It means an intervention needs to be accepted by its client system to yield
desired results: Experience shows that an intervention is likely be less acceptable unless sufficient
preparatory work has been done before introducing it.

11.2 Basic Components of Assessment of OD

In order to undertake an assessment program it is necessary to identify the basic components of
assessment. They are as follows:

 Objectives: It is synonymous to mission, goals or aims. The objective of an assessment at
the initial stages of the main change program is to gain knowledge and insight the efficacy
and design of the main change program. Objectives of intermediate evaluations at regular
intervals are to establish benchmarks.

 Worth or Value: for the focal variables which can be an individual, object, situation or a
program.
 Measurement: The technique of measurement of social variables is done through
psychometric tests. It is the quantitative dimension of the variable. Estimation of worth
can also be made by other methods which are qualitative like interviewing, observational
methods, simulation and projective techniques.
 Comparison: The data obtained from the measurement can be compared from the data
measured from other reference.
 Conclusion: It is arriving at a judgment after comparison is made.
