You have received a call from the manager of a firm where you helped set up a forecasting system. The manager, Jill Rodgers, expressed concern that forecast errors, although within the control limits, were too large, and wondered if there was anything else that could be done, or whether they would “just have to live with it.” What would you suggest? Write a memo to Jill.
Write a short memo to your boss, Jim Oliver, outlining the merits of using a control chart to monitor forecasts rather than a tracking signal.
