An effective and efficient logistics system is one which maintains sufficient, but not excessive, stocks on hand to meet users' needs. Logistics managers must decide when to buy and how much to buy. In order to make these decisions, managers need current and valid cost, demand, leadtime, and safety level data. GAO reviewed how the General Services Administration (GSA) and the Federal Aviation Administration (FAA) managers make these purchasing decisions.
