Partner is a label applied to suppliers with whom the buying organisation enjoys a longer term and cooperative relationship. It is part of a classification of potential buyer-supplier relationships, and represents a type of relationship in which both parties work to reduce waste, reduce cycle time, and create joint profit and other forms of value. The creation of joint working teams and the adoption of common work practices are linked to longer term relationships, in which both parties forego opportunism, and work towards longer-term goals. Such relationships are; however, time consuming to create and resource hungry. See also Cooperation, Lean Supply, and Win:Win.
