An effective purchasing strategy is at the core of successful purchasing departments. Strategies that offer total value to an organization should be the goal of all purchasing organizations. Purchasing professionals around the world are always in search of new strategies that creatively reduce costs and add previously unrealized value to an organization. Since motivating multi-company groups is difficult, the purchasing department must offer a clear strategy that offers value to all involved. Hence, Purchasing Programs, procuring products plus services, is a strategy that can be employed successfully to bring value to all involved. The theory of Purchasing Programs is to leverage vendors to offer products and services — whereas previously — vendors were only offering products.
