A. Traditionally, performance evaluation was performed by the employees
immediate supervisor. A variety of perceptual errors by supervisors can occur,
including:
Halo effect – rater allows one positive or negative trait, outcome or consideration
to influence other measures.
Stereotyping or personal bias – rater makes performance judgments based on
characteristics of employee, not performance.
Contrast error – employee assessment is based on those being given to other
employees.
Recency error – evaluation is biased toward events and behaviors immediately
preceding the evaluation.
Central tendency error – evaluator avoids the higher and lower ends of
performance assessment ratings.
Leniency or strictness error – employees are generally all rated well above or well
below average.
B. Many managers have no true knowledge of the technical or other skills that a
worker may have or the ability to observe the employee and the means by
which the employee accomplishes work. Other individuals, such as peers,
customers, subordinates, or others could provide insights into an employee’s
performance. The employee her/himself could also provide self-assessment date.
Multi-rater or 360 degree feedback uses some combination of assessments by
various individuals. Example – Peer Assessment at Coffee &
Power and Performance Management at Otis Elevator.
C. Supervisors might also intentionally inflate or deflate employee ratings. In
addition supervisors and subordinates may agree on levels of performance
but disagree on the reasons for such.
VI. WHAT TO EVALUATE
Example – Competency-Based Performance and Development at Capital
One. Employee evaluations can be made based on their traits (not recommended),
their behaviors or the results or outcomes they achieve.
A. Behavior-based measures focus on what the employee does by examining
specific behaviors, although observed necessary behaviors do not
guarantee success or results.
B. Results-based measures focus on specific accomplishments or direct
outcomes. However, not all jobs have measurable results; sometimes
external events influence results; and results focus on the end and not the
means, which may be very important.
C. Outcomes-based measures focus on specific accomplishments or direct
outcomes of the employee’s work. While often most meaningful to
organizations, these measures have some limitations as to their usefulness.
VII. HOW TO EVALUATE
Absolute or relative measures can be used to evaluate employees.
A. Absolute measures evaluate employees strictly according to performance
