Serco places Operational Excellence at its core and is a European leader in Service Integration and Management (SIAM). SIAM provides a single point of responsibility for the management and delivery of all services delivered by both internal and external service providers.

SIAM is an approach to managing multiple suppliers of services (business services as well as IT services) and integrating them to provide a single business-facing IT organisation. This management method has been adopted by Serco corporate IT Shared Services to deliver our Information Technology Infrastructure Library (ITIL) catalogue of services. With the introduction of SIAM on top of ITIL, Serco can manage market leading service providers and deliver seamless solutions to our customers.
