The owner of Touchdown Sports Bar wants to develop a time standard for the task of mixing a specialty cocktail. In a preliminary study, he observed one of his bartenders perform this task seven times with an average of 90 seconds and a standard deviation of five seconds.
What is the standard time for this task if the bartender worked at a 20 percent faster pace than is average, and an allowance of 10 percent of job time is used?
Providence Assessment Center screens and trains employees for a computer assembly firm in Boston. The progress of all trainees is tracked, and those not showing the proper progress are moved to less demanding programs. By the tenth repetition, trainees must be able to complete the assembly task in 1 hour or less. Susan has just spent 5 hours on the fourth unit and 4.5 hours completing her eighth unit, while another trainee, Julie took 4 hours on the third and 2.8 hours on the sixth unit. Should you encourage either or both of the trainees to continue? Why? Present calculation steps.
[Hint: For each trainee, 1) Determine the learning rate (%) – use doubling concept. 2) Calculate time for the 1st unit (T1) – use table, 3) Calculate time for the 10th Unit (T10) –use table]
