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?
The “worker” in this scenario had to perform a candy-sorting task and the rest of the class had to record the observed times (OT) for the task.
It was decided that the rating for the “worker” was 100%.
Given the following table, find the standard time for each element. Write your answers in order from Element #1 --> Element #5. Answers must have one decimal place: e.g. 3.0 or 12.5. Round up if necessary.
Assume a total allowance of 5%. In your equation you will use for ST, consider allowance to be 0.05.

- 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] Susan Julie Learning rate (%) – doubling concept Time for the 1st unit Time for the 10th unitarrow_forwardFrank is a long-haul truck driver.

A great deal of learning on the part of management and employees was required. Even though pressure was mounting to get a new product to market in early 2012, the production manager of the newly formed automobile division insisted on almost a year of trial runs before sales started because workers have to do their jobs 60 to 100 times before they can memorize the right sequence. The launch date was set for early 2013. What are the consequences of using this approach to enter the market with a new product?arrow_forward

Where you work on aparticular day is entirely up to you. It may be hard to remember, but office allocations were auniform signal of hierarchical status and part of organizational culture until recently. Asorganizations have become flatter and the need for creativity and flexibility has increased, the“open office” plan has become a mainstay of the business world. The goal is to encourage free-flowing conversation and discussion, enhance creativity, and minimize hierarchy—in otherwords, to foster a creative and collaborative culture and remove office space from…arrow_forward
