"I had professor Machol at Kellogg in 1985 for Operations. Professor Machol was intimidating. Rumor around the class was that he had been in charge of logistics for the U.S. Navy in the Pacific theatre during WWII. He was teaching EOQ modeling in one early class, leading me to pose a question, ‘Professor Machol, would it not make sense to do … for the sake of consistency’. His reply is oh so memorable almost 40 years ago.. “Mr. Clark, consistency is the bugaboo of small minds” (ouch!). No doubt relative to this giant, my mind was and remains small indeed!"
