Quality & Process Outsourcing (QPO) involves outsourcing business processes and IT functions to improve quality and reduce costs. The QPO methodology involves two steps - engage and disengage. During the engage step, the QPO partner works with the client to define processes, deploy solutions, conduct audits and create dashboards and improvement plans aligned with the client's business and IT strategies. In the disengage step, the partnership ends and control is transitioned back to the client. QPO delivers benefits like transformation and supports frameworks like CMMI, ISO and ITIL. The document provides examples of clients and services in various domains like ERP implementation, testing and process improvement.
