Based on my calculations and graph created. I need help answering the following questions using this data shown:
1.) Choosing between the three-period and the five-period forecasts, which length of averaging would you use as a purchasing manager of Greenfields Tannery? Be sure to factor in the cumulative forecast errors in your answer. Also, make sure you include some rationale about why you are picking the method you do for this particular business. So for example, does picking one method over the other have any impact on how much inventory they will have on hand to meet customer demand? What happens when the demand drops? Which method better supports that? Just saying the shorter period reacts more quickly to demand and the longer period smooths things out is not sufficient. Understanding and relaying how the choice impacts inventory levels and inventory costs to the business during slack and peak times, is the competency being assessed.
