Question
Activity 4A:
I conduct performance ratings for two employees of the same nature of work using the Westinghouse Rating System.
The observed time for an operator to finish a task which is tightening of screws for 2 minutes. His ratings were noted, as follows:
Good skill, C1 + 0.06
Excellent Efforts, B1 + 0.08
Average condition, C + 0.02
Good consistency, C + 0.01
Total Westinghouse Rating + 0.17
The normal time for that operation would be = 2.0 x 1.17 = 2.34 min.
To find the standard time at 20% allowance,
= 2.34 x 100 = 2.92 min.
(100 – 20)
Explain.
Be able to describe your basis, or give comments, on how you came up with their total rating. Set the standard time at 20% allowance.

Note: Correction on Conditions, C = 0.02; Consistency, C = 0.01
Summarized formula for calculation:
Westinghouse rating = Sum of ratings,
i.e. rating of (Skill + Effort + Conditions + Consistency) as given in Westinghouse tables.
Rating Factor = 1 ± Westinghouse Rating
Normal Time = Observed time x Rating factor
100
Standard Time = Normal Time x (100 – Total allowances in percentage)
