1. A Methods and Measurements Analyst needs to develop a time standard for a certain task. The task involves use of 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 perform this task five times. The observations were made in an air-conditioned, well- lighted 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 are 8% constant and 6% variable?

Unformatted text preview: d. If the analyst then thought more carefully about his experiment, and decided that the variable allowances needed to be increased to match the real (outside, unair-conditioned) work environment, and that the proper variable allowance was not 6% but 12%, what is the revised standard time? 2. An operation in a television factory has an average observed time of 6 minutes. The performance rating of the worker timed was estimated at 90%. Practice in this department is to allow 8% for the constant allowances. Currently, there is no variable allowance. a. Find the normal time for the operation. b. Compute the standard time for the operation. c. Recompute the standard time if a variable allowance of 8% is factored in....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
