Web4. Work sampling is also used to find out time standards, specially where the job is not repetitive and where time study by stop-watch method is not possible, e.g. for maintenance work, office work, repair work, ship building etc. Time standards can be calculated by combining rating with work sampling as illustrated in the following example: WebA = Average of actual time obtained in the time study for that element. Then R = P/A 4. Objective Rating: In this method, Rating is done in two stages, in first stage, operator’s …
