What is Quality Management of Outsourcing Services?
Using the outsourcing model, the enterprise shifts the responsibility for ensuring the quality of the transferred processes to an external provider, while the responsibility for the formation of parameters that determine the quality of the process lies with the enterprise itself. These parameters should be recorded in the SLA and controlled by the customer's IT service. This is true, except when it comes to outsourcing business processes. In this case, the responsibility for the implementation of the business process lies entirely with the external provider.
