Joint service agreement. a document used in conjunction with a contract to define the processes, performance targets and expectations of both an OEM and a contract manufacturer. The joint service agreement should be specific in terms of how the work will be done and evaluated. It should be supplemented by a management control system that requires a regular review of performance against the JSA expectations. This approach helps minimize the misunderstandings that often develop in outsourcing relationships. Also see "manufacturing and supply agreement."
