Proof that big doesn't always mean slow and inefficient, Lockheed Martin posted high scores in all four TPC metrics, pushing it to the top of this year's rankings. A beneficiary of robust Pentagon spending, the company has consistently improved its earnings by attacking costs, improving its supply chain, and implementing common systems across a group of previously far-flung units. Acquisitions in adjacent markets such as port security are diversifying its portfolio.
