Question

​Billy's Hamburger Barn has a single​ drive-up window.​ Currently, there is one attendant at the window who takes the order ​(20minus30 ​seconds), gathers up the food and bags it ​(55minus90 ​seconds), and then takes the​ customer's money ​(25minus35 ​seconds) before handing the food to the customer.A) Map the current process. What is the minimum cycle time? The longest cycle time?B) Suppose Billy's Hamburger Barn redesigns the process so there are now two attendants. The first attendant takes the order. Once this step is finished, the first attendant then takes the money, and the second one gathers up and bags the food. If two of the process steps can now run in parallel (gathering the food and taking the money), what is the new minimum cycle time? What is the longest cycle time? What potential problems could arise by splitting the process across tow individuals?

Answer 1

Answer:

The map of the current process is found in the attached

The minimum cycle time is 1 min 40 seconds

The longest cycle time is 2 min 35 seconds

The new minimum cycle is 1 min 15 seconds

The new longest cycle time is  2 mins

The potential problem that could surface from splitting the process is that once the customer has finished paying the customer has to wait for about 30 to 55 seconds before the second attendant finishes with packaging,hence ,a queue would likely be formed awaiting the second attendant.

The problem could be solved by ensuring the taking money and packaging takes the same time.

Explanation:

Minimum cycle time=20+55+25=100 seconds=1 minute 40 seconds

The longest cycle time=30+90+35=155 seconds=2 min 35 seconds

The new minimum cycle time=20+55=75 seconds=1 min 15 seconds

Taking customer's money also happened in the first 35 seconds of the 55 seconds above.

The new longest cycle time=30+90=120 seconds=2 mins
