Based on data analysis the best method for forecasting Highline Financial Services for the upcoming year would be the Moving Average (McNamara‚ 2012). The Moving Average offers the lowest Mean Absolute Deviation ( MAD)‚ lowest means squared error (MSE)‚ and the lowest mean absolute percent error (MAPE) of the two choices selected to forecast. The weighted moving average was not utilized due to the amount of data provide. The ability to

There is no perfect forecast‚ management should try to find and use the best forecasting method available.

This model is useful when you have a short time requirement (eg days) to analyse products in their growth stages to predict short-term outcomes. To use this model you look at several historical periods and choose a method that minimises a chosen measure of error. Then use that method to predict the future. To do this you use detailed data by SKU’s (Stock Keeping Units) which are readily available. In TSM there may be identifiable underlying behaviours to identify as well as the causes of that behaviour

much an art as a science. Students should understand that qualitative analysis (judgmental modeling) plays an important role in predicting the future since not every factor can be quantified. Sometimes the best forecast is done by seat-of-thepants methods. Teaching Suggestion 5.3: Use of Simple Models. Many managers want to know what goes on behind the forecast. They may feel uncomfortable with complex statistical models with too many variables. They also need to feel a part of the process. Teaching
