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.
