Performance rating

Meaning in industrial engineering & manufacturing, with examples

nounAdvanced term

In industrial engineering & manufacturing, performance rating means: In time study, the analyst's judgment of how fast a worker is working compared with a normal pace, used to turn observed time into normal time.

In Turkish: performans değerlendirmesi, tempo takdiri, performans faktörü

How it is used

Given as a percentage: 100% is normal pace, and 110% means faster than normal. Normal time = observed time × rating. Rating takes training and practice, and workers and unions often question it because it is partly subjective.

Example sentences

  1. The observed time was 50 seconds and I gave a performance rating of 90%, so the normal time is 45 seconds.

  2. Two engineers rated the same video to check that their performance ratings agree.
