John’s key points are these. • Organizations should consider which service level measure aligns most closely to their corporate objectives. Cost of Forecast Error (CFE) calculations should be based on this measure. • Assessment of service level targets at higher levels of aggregation elevates an operational task to a strategic issue and facilitates consideration of external factors. • Alternative approaches which do not depend on Cost of Forecast Error estimates, such as tradeoff curves, should be considered.
