Based upon this breakdown of each process, we can surmise that from the time an order comes in, to the time that the customer pays for the cookies is 23 min. Based upon this breakdown of processes and responsibilities, there may be room to increase production based upon how much time each member of the team spends working on the production of one dozen cookies. 2.How many orders can you fill in a night, assuming you are open four hours each night?We base the capacity on where the bottleneck exists. Currently, the bottleneck exists during the actual bake step. This bottle neck is caused by this step taking 9 mins to perform. Since there are 60 mins in an hour, we can find the hourly capacity by dividing one hour into 9 min intervals. We find that 60/9 = 6.667 cookies an hour or 26.668 cookies in a 4-hour shift. Because setting the instruments and placing the tray of cookies into an oven are essential to the baking step, we can combine the two, producing a new bottleneck of 10 mins. 60 mins/10 mins= 6 orders. That equates to 24 orders in a 4-hour shift. This figure is more believable as it would likely include wait times and end pf the nigh cleanup operations.
