Summary
IT4IT Reference Architecture Functional Component
Reference
Purpose
- Identify the new or existing services required to meet the needs of the Scope Agreement and IT Initiative, including both service systems and service offers.
- Leverage the Conceptual Service Blueprint and Portfolio Backlog Items from the S2P Value Stream along with requirements to produce a Logical Service Blueprint that describes the service structure and behavior considering both the service system and the service offer.
- Creation of various architectural artifacts (data flow diagrams, technical schematics, etc.) that comply with the IT Initiative specifications and boundaries.
- Creation of the service design specification document (Service Design Package).
- Identification of the service delivery model (in-source, outsource, etc.).
- Identification of service suppliers to meet the requirements within the chosen delivery model.
- Enable interaction with IT operations to develop support plan/requirements for an IT service.
- Ensure that the architecture and Service Design Package are compliant with all standards and policies, including security standards and policies.
- Ensure that the architecture and Service Design Package meets all requirements including security requirements to ensure the confidentiality, integrity, and availability of the service.
- Put instrumentation in place so that IT can capture empirical data about how IT services are performing rather than relying only on anecdotal input from the user community.
- Ensure that the service is architected to meet the KPIs and SLAs.
- The output of the Service Design functional component is used by the Source data object to source, create, and secure the service.
