- 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 88 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 10% faster pace than is typical for adequately trained workers? (c) What is standard time for this task if allowances sum to 12%? (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…AsapVirginia College promotes a wide variety of executive training courses for firms in the Arlington, Virginia, region.
