I’m doing the excercise of the drive tree within the chaptter of Benchamarking excercise.
Checking the solution offered in the chapter, I did not understand why calculating the numbers of shifts per day and night, the results are 300 day shifts and 75 night shifts. In my opinion, the answer might be 300 day shifts and 63 (62.5) night shifts. This is because, if the company produces 800 units each 12 hours and uses it 300 days per year, the company can produce 240.000 out of its goal of 290.000. This action leaves 50.000 units to produce in the night shift, so dividing 50.000 units in 800 units per shift gave me 62.5 night shifts instead of 75.
I would like to know if I’m not considering a variable that gives the result exposed in the excersice.
I appreciate your time reading this.
Thanks for pointing this out. Yes, that’s a calculation mistake on our end. It should be 62.5.
We’ll fix this as soon as possible.
Hi, I was having the same trouble. Also by calculating the Labour Cost per hour we need to go like this: (3,600 hours * 15 $ per hour * 20 employees) + (750 hours * 20 $ per hour * 20 employees). I hope you will adjust the results, they are very different this way. Otherwise it’s a bit confusing.
