Today, companies and IT departments have become increasingly dependent on IT service providers for many of their services. This is driven by several reasons and global trends: a focus on core processes, cost reduction, taking advantage of working with external service providers. Outsourcing was introduced as early as the 1970s and 1980s; it was formally recognized as a business strategy in ’98 and has grown rapidly ever since.
However, without effective orchestration and management of the various service providers, many of the hoped-for benefits will not be realised for the client organization. Gartner even states “Governance is key to successful multi-sourcing”.
SIAM (Service Integration and Management) is a methodology for companies that purchase services from different suppliers, and want to get maximum added value from them without having the disadvantages of have to deal with different parties, with different ways of working, different people, different contracts, different tools.
