however, suffer from a long standing disadvantage, i.e., it
may be arbitrary and the rating may be subjective. Another
pitfall is that each characteristic is equally important in
evaluation of the employee’s performance and so on.
6. Behaviourally anchored rating scales: Also known as the
behavioural expectations scale, this method represents the
latest innovation in performance appraisal. It is a combination
of the rating scale and critical incident techniques of
employee performance evaluation. The critical incidents
serve as anchor statements on a scale and the rating form
usually contains six to eight specifically defined performance
dimensions.
7. Forced choice method: This method was developed to
eliminate bias and the preponderance of high ratings that
might occur in some organisations. The primary purpose of
the forced choice method is to correct the tendency of a rater
to give consistently high or low ratings to all the employees.
This method makes use of several sets of pair phrases, two
of which may be positive and two negative and the rater is
asked to indicate which of the four phrases is the most and
least descriptive of a particular worker. Actually, the
statement items are grounded in such a way that the rater
cannot easily judge which statements apply to the most
effective employee.
The favourable qualities earn a plus credit and the
unfavourable ones earn the reverse. The worker gets an
overall plus rating, when the positive factors override the
negative ones or when one of the negative phrases is
checked as being insignificantly rated. They overall objectivity
is increased by using this method in evaluation of employee’s
performance, because the rater does not know how high or
low he is evaluating the individual as he has no access to the
scoring key. This method, however, has a strong limitation. In
the preparation of sets of phrases trained technicians are
needed and as such the method becomes very expensive.
Further, managers may feel frustrated rating the employees
‘in the dark’. Finally, the results of the forced choice method
may not be useful for training employees because the rater
himself does not know how he is evaluating the worker. In
spite of these limitations, the forced choice technique is quite
popular.
8. Management by Objectives (MBO): MBO requires the
management to set specific,measurable goals with each
employee and then periodically discuss the latter‘s progress
towards these goals. This technique emphasises
participatively set goals (that are agreed upon by the superior
and the employee) that are tangible, verifiable and
measurable. MBO focuses attention on what must be
accomplished (goals) rather than how it is to be
accomplished. It is, thus, a kind of goal setting and appraisal
programme involving six steps:
