SDC is the only industry, standard based accreditation programme designed specifically to certify service desk quality. Service Desks Worldwide use the Certification programme as a differentiator against competitors, to structure their continual improvement initiatives and to prove the value of their service to customers and the wider business. The SDC Assessment process investigates and reviews the service desk and its support teams to ensure that consistent service delivery is being provided to the customer base using sound and resilient policies, processes, procedures, knowledge, skills, systems and technology.
