Perfomance measurement must capture single effort

Memory Nguwi

MOST performance management systems suffer from two main perennial problems; measurement problem and feedback problem. Regardless of what your system is called, these are the main problems that make most performance and measurement systems useless.

I know many organisations have different systems, some very old and some new and with fancy names. Unless and until the two problems are addressed, the system will not work. You may have noticed that some organisations are abandoning performance assessment altogether.  Here are the major issues related to performance management.

The measurement problem; Regardless of the system you are using, Observed Performance = True ability (effort) + Error (Luck).  If your performance measurement system is to be good at any level, it must minimise the amount of error in the measurement system. It is impossible to get rid of all the errors in the measurement of performance.

To reduce this amount of error, the system must be as objective as possible.

In practice, we know that most systems are very subjective, making them unsuitable for differentiating between good performers and bad performers.

When your measurement system can capture the true ability or effort of the individual in the observation of performance, half your job is done.

One of the true characteristics of good performance is that whatever is being measured must show some element of consistency. Variation in performance is mainly a result of an error in the measurement instrument.

For example, “playing lotto” does not reflect the true ability or effort of the individual.

Whether you win the lotto or not is a function of luck more than skill. Most of the performance measurement systems we see on the market are like playing “lotto”. They do not reflect the true ability or effort of the employee; instead, they show that luck or measurement error is at play.

If your system cannot objectively distinguish between good performers and poor performers, it means it’s not a good system.

Feedback Problem: The problem related to feedback is complicated by the first problem of measurement.

If your measurement system is not objective and giving employee feedback is very difficult. Employees resist subjective and inaccurate assessments. This is precisely why most employees hate performance appraisals. However, managers do not seem to learn, and they continue with a faulty feedback mechanism.

No Consequences:  What happens if an employee performs and what happens when they do not? If there is nothing in both cases, your performance management system will never work even if you address the first two problems.

People change their behaviour because of what happens to them after performing to a certain level.

Long Appraisal Forms; A good appraisal form should not be more than one page. Anything above two pages will be resisted. A good appraisal form prioritises the goals that need to be achieved, and these cannot be more than one page.

Not training users — Once all the above key issues are addressed, you need to make sure every system user is adequately trained. When users know how the system should work, they usually put effort to do it properly.
