- 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. Observation: 1 2 3 4 5 Task time (seconds): 82 74 80 83 76 a. What is the actual average time for this task? b. What is the normal time for this task if the employee worked at a 20% faster pace than is typical for adequately trained workers? c. What is standard time for this task if allowances sum to 14%? d. If the analyst then thought more carefully about his experiment and decided that the allowances needed to be increased to match the real (outside, not air-conditioned)…arrow_forwardHow reliable is the result of work sampling activity in determining working time and idle time of the operator?arrow_forwardGive other examples or illustrations of work sampling studies.arrow_forward
- Discuss the role of work sampling in job design and process improvement initiatives.arrow_forwardDecision makers need to consider three primary considerations when designing jobs; list and explain the component or job designarrow_forwardA worker-machine operation was found to involve 3.3 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. The worker's time-averaged 1.9 minutes per cycle, and the worker was given a rating of 120% (machine rating is 100%). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 12% of work time, determine the standard time for this job. Hints: you should consider both machine time and machine time together. Also, Allowance only applies to the man, not a machine.arrow_forward
