For the past 10 years, analyst firm Gartner has compiled an annual ranking of companies that have the best supply chains in the world. Now, it needs to be said at the outset that not every company is considered for the Top 25 list. First of all, they have to be public companies. Second, they have to have at least $10 billion in annual revenues. Third, they have to be manufacturers, retailers, or distributors. Fourth… well, Gartner has so many exceptions to what constitutes an eligible company that it’s sometimes a head-scratcher to figure out exactly what kind of a “supply chain” Gartner is looking for.
