Recently I read an article published by a smart guy. I know he must be because he holds a Master of Science and a Bachelor of Arts degree. He is also an “international master trainer and award-winning author” writing on supply chain and other management topics. [He shall go unnamed in this article, however, for reasons that may become apparent below.]
Therefore, you can imagine my shock when I read that, in his opinion, what it takes to optimize inventory, at a minimum, are: “fixed, known, certain, [and] reliable lead times; and accurate demand forecasting.”
This, I believe, will mean that a very small number of businesses will ever optimize their inventories.
