Service Integration and Management roles and responsibilities
This domain tests who is accountable for what across the ecosystem, how roles differ from job titles, and why process ownership must sit with the service integrator rather than a delivering provider.
Three role groupings
Roles are defined at three levels, and the same role name can be held by people in different organisations:
- Customer organisation - business relationship management, demand, service governance and commercial ownership.
- Service integrator - end-to-end accountability: SIAM process owners, service level management, service performance, supplier management, service catalogue, transition coordination and continual improvement.
- Service providers - delivery roles: process managers and practitioners, technical specialists and provider service managers.
Rules
- A role is a set of responsibilities, not a person or a job title; one person may hold several roles, but accountability for a given process must be single and unambiguous.
- Each end-to-end process has one owner, located in the service integrator, who designs the process, sets policy, defines KPIs and interfaces and assures compliance. Providers host the process managers and practitioners who execute it.
- Interfaces between roles are documented with RACI (responsible, accountable, consulted, informed) so that handoffs between providers are explicit.
- Providers are accountable for their contractual commitments; the integrator is accountable for the integrated end-to-end service.
Worked example
A major incident spans a hosting provider and an application provider. RACI reasoning: the integrator's major incident manager is accountable; the hosting provider's incident manager is responsible for its diagnostic actions; the application provider is consulted on dependencies; the business relationship manager is informed. Without a single accountable major incident manager, both providers escalate inside their own silos and the business waits.
Traps
- Placing process ownership in the largest or most technical provider - it creates a conflict of interest and fragments end-to-end control.
- Confusing accountable with responsible in RACI questions; accountability cannot be delegated across providers.
- Drawing roles as an organisation chart of named individuals rather than responsibilities.
- Forgetting that provider-side roles such as process managers and practitioners are part of the SIAM role model.
