What is Service Integration and Management (SIAM)?
SIAM is an operating model for the integrated management of ICT in a multi-supplier environment, whereby an organisations IT department retains key functions such as strategy, architectural ownership, standards and policies, with the SIAM provider responsible for the impartial, standardised governance, assurance and management of service delivery by in-house and external suppliers that are typically grouped into ‘Towers’.
SIAM addresses the challenges of:
- High cost of existing service delivery and service management functions
- Inconsistent quality of services delivered across the ICT supply chain
- Risk and inflexibility of large scale single ICT supplier outsourcing contracts
- Inability to benchmark supplier value and compare performance across suppliers
- Limited ability to rapidly leverage niche specialist supplier skills
- Ineffective management of demand and supply
By adopting a SIAM operating model, organisations can select and procure services, products and technologies in a more agile and structured manner, without the limitations of traditional end–to-end services procurement. Used effectively, SIAM’s ‘mix and match’ approach can free up organisations from vendor lock-ins, and enables coexistence within the same operating framework of large-scale commodity suppliers with niche SME suppliers that can be leveraged for innovation in delivery.
SIAM can enable the integration of both digital and traditional infrastructure services within a single operating model, and can bring process excellence and clear, multi-level governance that can transform ICT delivery. The structure of the SIAM operating model is not ‘one size fits all, and can be tailored through consultation to meet the specific needs of each organisation, allowing the organisation to choose the level of retained versus outsourced service integration responsibility, based on retained IT organisation capability and maturity.
Atos’ SIAM model

- Avoids supplier, brand, or timescale ‘lock in’ and end-to-end service silos
- Enables a ‘best-of-breed’ approach from the most appropriate specialist providers within a flexible ‘plug-and-play’ environment
