FOR A LONG TIME, Ed had noticed that virtually all inventory management books cover various techniques with little or no mention of the operational situations for which they are suitable. The main theme of the book HANDS ON INVENTORY MANAGEMENT is that operational situations govern the suitable techniques to use. Pre-engineered manufacturing situations require different techniques from retail. Make-to-order situations requires different techniques from make-to-stock. And so on. Firms need to first understand and agree internally on their respective operational situations before selecting from among various inventory techniques.
Also, inventory management tools become effective only when certain prerequisites are met. These prerequisites include, among others: good housekeeping, records accuracy, simple systems, alignment of department goals.
