It might be considered that the decision to use separate sheets for each pricing scenario is a somewhat inelegant solution and makes the model more cumbersome and complex than it needs to be. Indeed, the fixed price optimisation and what if functions could all have been run from the manual price input sheet. However, it can be argued that the use of a main menu and the separation of different functions make the model easier and quicker to use. For example, for a performance where ticket prices are fixed, the manager can very quickly obtain optimal ticket prices and expected profit without having to spend time stepping through the 15 day simulation. In addition, the separation of different functions into different sheets makes it easy to appropriately navigate the user through the model based on the options they select. Finally, separating pricing functions in to different sheets ensures that each user interface is not overloaded with different options, making the model far simpler to use.
