Service integration and management

Service Integration and Management (SIAM) is an approach to managing multiple suppliers of services (business services as well as information technology services) and integrating them to provide a single business-facing IT organisation. It aims at seamlessly integrating interdependent services from various internal and external service providers into end-to-end services in order to meet business requirements.[1][2]

Background

Bolstering information technology capabilities and capacity using multiple external suppliers is becoming a dominant operating model for many large enterprise IT organisations. This model is commonly known as multisourcing.

Sourcing from multiple IT suppliers allows an organization to maintain in-house technical teams or large single source suppliers, and become more adaptable by taking advantage of competitive marketplace behaviors which incentivise cost reduction and leverage innovation. The use of multiple best of breed suppliers can incur large management overhead costs and lead to difficulty in managing end to end (e2e)services. SIAM thinking has developed to aid that management challenge.

The term SIAM was predated by the term Service Integration which has been in use since at least 2009.[3] It should not be confused with the term System integration. Unlike ITIL (for IT service management) and PRINCE2 (for project management) it is not a framework and does not yet have an established body of knowledge. Instead it is largely implemented in line with proprietary models developed by large IT service providers, including Accenture, HCL Technologies, Cap Gemini, CSC, Atos, TCS and IBM to meet requirements developed by third party advisors, notably KPMG, Gartner and ISG. In UK government it is seen as a way for large governmental IT organisations to better manage and control multi-sourced operations, by compiling (and then sharing between themselves) their best practices and their most successful management methods.[4]

SIAM is a rapidly developing area of service management, and one that is closely associated with multiple disciplines including IT service management, enterprise architecture, organisational change management, quality management and risk management.[1]

Key Concepts

SIAM introduces some of the following key concepts for effective Service Management:

IT Capabilities

In order to perform effective and efficient service integration and management, multi-sourcing clients require key IT capabilities. They need to build and continuously improve these capabilities for performing successful service integration and management. In total, research identifies six key IT capabilities that clients should build and optimize.

  1. Manage Service Integration Governance: Multi-sourcing organizations need to be able to define, establish and continuously adapt the service integration governance.
  2. Manage the Service Integration Organization: Multi-sourcing organizations need to be able to develop and manage the distributed organization in accordance with changing business requirements.
  3. Manage the Business: Multi-sourcing organizations need to be able to manage business demand and develop a service portfolio in alignment with business requirements.
  4. Manage Tools and Information: Multi-sourcing organizations need to be able to manage distributed information and the integration tool solutions.
  5. Manage Providers and Contracts: Multi-sourcing organizations need to be able to select an appropriate provider portfolio and to manage the providers according to the outsourcing contracts
  6. Manage End-to-end Services: Multi-sourcing organizations need to be able to understand and manage the business services end-to-end. This includes consolidation of business as well as IT services especially during mergers & acquisitions and demergers & spinoffs. Integral part is IT service management including relevant processes.

A conscious and systematic implementation of these capabilities should contribute to the effectiveness of multi-sourcing engagements and overall multi-sourcing success.

Challenges, issues and benefits

When services are provided by myriad teams or suppliers, ensuring seamless service delivery to the business or organization being served presents a challenge. To sustain the benefits, strong operational and commercial governance are essential.

According to research, service integration and management needs to address and overcome four key challenges:[1]

  1. Measuring services end-to-end
  2. Aligning scope and specifications across provider contracts
  3. Managing relationships and collaboration with and between providers
  4. Defining standardization and modularization

Service integration and management functions have to manage these key challenges in order to prevent common issues with SIAM and realize its key benefits.

Some common issues include:

Some key benefits of moving to a well managed multisourced IT organisation can include:

SIAM aims to bring the desired governance and control which will ensure organisational policies and standards are not ignored or inconsistently applied; and suppliers act in a cohesive and efficient manner.

Organisational structure

The creation of a SIAM team, who act as the single point of accountability and orchestrate multiple suppliers, is seen as an effective way of minimizing or mitigating potential multisourcing issues, and optimising the composite IT organisation.[5]

A SIAM function, department or team will typically:

Examples of specific activities that a SIAM team would undertake include: assessing changes to the infrastructure and applications; managing the resolution of incidents which affect a service supported by multiple service providers; and coordinating disaster recovery. In addition, a SIAM team would act as the gatekeeper by enforcing change, security accreditation, testing and release processes.

Five different organizational models exist to institutionalize service integration and management in multi-sourcing settings with interdependent services. The models describe the position of the organizational unit that is performing service integration and management:[2]

  1. Retained Organization: The client itself can take responsibility for service integration. Its retained organization is accountable for coordinating and integrating the services.
  2. Prime-Vendor: Service integration is performed by the clients single prime-vendor. The prime-vendor has the obligation to sub-contract parts of the services to third party providers and to integrate their services.
  3. Guardian Vendor: One of the clients’s existing service providers is responsible for service integration in addition to its original service delivery responsibilities.
  4. Independent Service Integrator: An independent third party company is responsible for service integration without additional service delivery responsibilities.
  5. Shared Service Integration: Service integration responsibilities are distributed across the client and all of their service providers. It represents a hybrid model of the other four organizational models.

Hence, a key feature of the SIAM approach is that the SIAM team might itself be sourced either entirely or in part from a supplier. Whilst it might be considered beneficial from a governance perspective for that supplier to have no other commercial interest in the provision of IT services to the customer in practice the SIAM provider is often the supplier with the largest contract value. In theory this means that they have the greatest interest in delivering a good service.

ITIL and SIAM

ITIL processes and capabilities provide a strong foundation for implementing SIAM because they cover the lifecycle of IT services, and the terminology is recognized and understood by most IT suppliers. ITIL, therefore, provides a strong platform and common language with which a SIAM team can manage and work with a full spectrum of suppliers. SIAM draws on other sources of best practice as well in specific domain areas, for instance COBIT5 and ISO/IEC 38500. Whilst ITIL provides high level guidance on many aspects of IT management relevant to SIAM it does not currently do so in the context of a multi-supplier eco-system. Axelos, the current owners of ITIL have announced that during 2015 they will be publishing whitepapers on SIAM.
