Work Sampling

Statistical observation technique that estimates the proportion of time spent in different activities from random observations.

Examples

01Over two weeks, 1,000 random work sampling observations show maintenance technicians spend 22 % of their time waiting for parts.
02The work sampling plan is reviewed so observations cover all shifts, weekdays and times of day.
03After a parts kit is prepared for planned jobs, a new work sampling study shows waiting time falling to 9 %.
