A 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.
Jell Lee Beans is famous for its boxed candies, which are sold primarily to businesses. One operator had the following observed times for gift wrapping in minutes: 2.3, 2.7, 2.4, 2.4, 2.3. The operator has a performance rating of 110% and an
allowance factor of 10%.
The standard time for this gift-wrapping operation =
minutes (round your response to one decimal place).
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 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)…
