A Methods and Measurements Analyst needs to develop a time standard for a certain task. The task involves use of a ruler, square, and portable electric saw to mark and cut the "notch" in a rafter (a standard carpentry task of home construction). In a preliminary study, he observed one of his workers performing this task five times. The observations were made in an air-conditioned, well-lit training facility, at ground level, with all tools and equipment clean and readily available.

(b) What is the normal time for this task if the employee worked at a 10% faster pace than is typical for adequately trained workers? (c) What is standard time for this task if allowances sum to 12%?

The “worker” in this scenario had to perform a candy-sorting task and the rest of the class hadto record the observed times (OT) for the task. It was decided that the rating for the “worker” was 100%. Given the following table, find the Normal Time for each element. Write your answers in order from Element #1 --> Element #5. Answers must have one decimal place: e.g. 3.0 or 12.5 Element Trail 1 Trial 2 Normal Time 1 Walk to podium 3 sec 3 sec 2 Fill mug 5 sec 6 sec 3 Walk to desk/sit 5 sec 4 sec 4 Sort Candy 12 sec 12 sec 5 Walk to desk 4 sec 4 sec

For a time study of a health insurance claims-adjusting process, the analyst uses the continuous method of recording times. The job is divided into four work elements. Shown in Figure are the performance rating factors, RF, and the continuous method recorded times, r, for each work element.a. Calculate the normal time for this job. b. Calculate the standard time for this job, assuming that the allowance is 20 percent of the normal time. c. What is the appropriate sample size for estimating the time for element 2 within {10 percent of the true mean with 95 percent confidence?
What is the first step in the process of time control?
