The purpose of the Inspection and expediting service is to ensure the delivery of purchased goods to a pre-determined and promised delivery schedule or critical path network. It is the task of the expeditor to detect and analyse the areas, which might cause or entail delays. The expeditor must obtain or reaffirm delivery promises from suppliers, must fully investigate all aspects of the suppliers scheduling which are evidence of the practicality of achieving such promises and must physically check progress of all functions of the suppliers operations being engineering, procurement, production and shipping departments.
