The Government Procurement Service (GPS) has outlined its plans for a unified approach to service integration and management (SIAM) services across the public sector.

A prior information notice details a potential framework to interested suppliers, and according to TechMarketView, is intended to be part of a suite of new GPS frameworks to support the government's ICT Strategy.

These frameworks aim to move government towards disaggregated, multisource tower services that encompass networks & telecoms, hosting services, application development, delivery & support services and desktop services.

'Towers' are set up so that a company, or central government in this case, can provide different services across a whole organisation, which can be delivered by different suppliers, but are all centrally managed throughout the implementation process.

The Post Office recently released a similar £360 million framework that adopts the 'service towers' approach to provide IT services across the organisation.

The SIAM framework is set to be the first procurement to use the 'Cross Government Strategic SIAM reference set', which has been drawn up by GPS, the Department for Work and Pensions, the Ministry of Justice and the Department of Health, to promote this single strategic approach to SIAM across the public sector.

According to the PIN, the SIAM framework will be broken down into nine areas, which include core SIAM, service desk, service knowledge management, service assurance, IT information security support, service transition planning & support, service validation & testing, full SIAM service and transformation design and change services.

According to Tola Sargeant, director at TechMarketView, departments with particularly large or complex SIAM requirements will still be able to procure outside this central SIAM framework, but they would be expected to use the same strategic SIAM reference set.

Sargeant said: "A wide variety of suppliers may be interested in SIAM roles. They include the traditional IT services suppliers, which have confidence in service management and understand the towers (provided they can assure themselves that the risk-reward profile is appropriate), other service companies with a strong service management history (such as the defence contractors), the management consultancies (although they may need to partner with systems management tool providers), and SMEs (tail wagging several dogs?)."

If you are a supplier interested in the SIAM framework there's an industry day in October. Email [email protected] for more information.
