3. Case Study A small company has commissioned you to develop a useful spreadsheet modelling tool to support their demand forecasting on a weekly basis. The tool will be used by the Operations Manager who needs forecasts of demand for 1-4 weeks ahead to help him plan production. He also needs a useful way of monitoring the performance of forecasts that he can use in weekly and monthly management reports since this information will help inform inventory policies, for example. Data and Information To build, test and demonstrate the use of your modelling tool, the Operations Manager has made available the data in the spreadsheet "MS924 resit assignment data and can be downloaded from myplace page folder.
