An elementary school cafeteria is experiencing unusually high wait times as students move through the cafeteria line. It takes an average of $2$ minutes for each student to be served with an average of $6$ minutes per class. The students buying a school lunch have a decreased amount of time to each and the teachers are also impacted as they have less than $20$ minutes out of $25$ minutes scheduled to eat their own lunch. The school principal would like help identifying the problem and possible solutions to alleviate these issues before speaking with the cafeteria manager. Use little's law to make improvements to school cafeteria wait times. Number of students, average wait time and effective arrival rate listed in chart. Consider the following: What specific performance or outcome measures are you trying to improve?

What does success look like?

What is the status quo; does this measure vary over time?

How far are you from the target? Where are the bottlenecks? What alternatives are there to the current process

flow? What would be the value of an improvement? $\backslash$table$[[$Number of Students,Avererage Wait Time $($min$/$sec$),$Effective Arrival Rate$],[11,1,11],[17,1\mathrm{.}5,25\mathrm{.}5],[17,1\mathrm{.}5,25\mathrm{.}5],[15,1,15],[14,2,28],[14,2,28],[16,2\mathrm{.}5,52\mathrm{.}5],[15,2\mathrm{.}5,40],[12,1\mathrm{.}55,23\mathrm{.}25],[14,3,36],[14,2\mathrm{.}5,40],[14,1,14]]?$
