2. Time Study Procedure Select the job to study
Collect information about the job
Divide the job into elements
Do the actual time study
Extend the time study
Determine the number of cycles to be timed
Rate, level, and normalize the operators performance
Apply allowances
Check for logic
Publish the time standard
3. Determine the Number of Cycles to be Timed N = number of cycles to time study
R = range of the sample of observations
A = required precision
d2 = a constant to estimate the standard deviation of a sample
X bar = arithmetical average
4. Rate, Level, and Normalize the Operators Performance (Average time) x ( %rating ) = normal time
5. Apply Allowances Total normal time + allowances = standard time
6. Factors for Rating an Operator Skill
Consistency
Working conditions
Effort
