Assignment Overview
Scenario: You are a consultant for the Excellent Consulting Group (ECG). You have completed the first assignment, developing and testing a forecasting method that uses Linear Regression (LR) techniques (Module 3 Case). However, the consulting manager at ECG wants to try a different forecasting method as well. Now you decide to try Single Exponential Smoothing (SES) to forecast sales.
Case Assignment
Using this Excel template: Data chart for BUS520 Case 4, do the following:
1 Calculate the MAPE for Year 2 Linear Regression forecast (use the first spreadsheet tab labeled "Year 2 Forecast - MAPE").
2 Calculate forecasted sales for Year 2 using SES (use the second spreadsheet tab labeled "SES - MAPE"). Use 0.15 and 0.90 alphas.
3 Compare the MAPE calculated for the LR forecast (#1 above) with the MAPEs calculated using SES.
Then write a report to your boss in which you discuss the results obtained above. Using calculated MAPE values, make a recommendation concerning which method appears to be more accurate for the Year 2 data: SES or Linear Regression.
