## Further Questions

- Think about the inflow of customers to a restaurant and how that is influenced by the length of a queue given a fixed outflow. What will it look like as a function of time? The inflow rate will oscillate sinusoidally. So will the queue length. The inflow rate will oscillate about the fixed outflow rate while the queue length will oscillate about the average queue length. (Bonus question for the maths-savvy: will the queue length oscillation be in phase or out of phase with the inflow rate oscillations?) Try answering all these questions without using calculus but only using logic and common-sense assumptions.
- If you have skipped the calculation of why the mealtime for Ham needs to be reduced by 1/6 try to do it now to practice approximating tough problems with simple solutions.

This case is designed to practice breaking down quantities into its component parts. In this particular case, the revenue of a restaurant will have to be broken down. The case should be tackled in two phases:

Phase 1 (breakdown and benchmarking) should be about isolating the key factors that influence the revenue of a restaurant and then to compare those to the franchise average for benchmarking to identify the factors that can be improved.

Phase 2 (testing improvement options) should be about testing if it is possible to improve any of the factors that have been identified to improve overall revenue.
