You have received a call from the manager of a firm where you helped set up a forecasting system. The manager, Dr. Nancy Waldron, 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 Dr. Waldron.

How should I proceed to write this memo and what should be emphasized?
