Short Answer
Complete Explanation
The term Service Def System is an abbreviation for Service Definition System. It denotes a systematic approach to documenting, organizing, and governing the specifications of services offered by an organization, particularly within the domains of information technology service management (ITSM), service‑oriented architecture (SOA), and business process modeling. By providing a common language and structured repository for service attributes—such as scope, performance criteria, dependencies, and pricing—the system enables consistent delivery, easier integration, and more effective governance of services across internal and external stakeholders.
- Core purpose:
To create a single source of truth for how services are defined, measured, and consumed. - Typical components:
Service catalog entries, service level agreements (SLAs), metadata schemas, and workflow templates. - Key benefits:
Improved alignment between business needs and technical delivery, reduced duplication, and enhanced automation of provisioning and monitoring. - Industry standards:
Often aligned with ITIL (Information Technology Infrastructure Library) practices, ISO/IEC 20000, and TOGAF (The Open Group Architecture Framework). - Related technologies:
Configuration management databases (CMDBs), enterprise service buses (ESBs), and API management platforms.
Common Misconceptions
Service Def System is a software product.
It is a methodological framework; organizations may implement it using various tools, but the concept itself is not tied to a single vendor.
The system only applies to IT services.
While common in ITSM, the principles can be extended to any service‑based offering, including facilities, HR, or cloud services.
Defining services once is sufficient for the long term.
Service definitions must be regularly reviewed and updated to reflect changing business requirements and technology landscapes.
FAQ
Is a Service Def System the same as a Service Catalog?
No. The Service Definition System is the methodology and set of processes used to create and maintain the service catalog, which is the actual list of services made available to users.
Can a Service Def System be used for non‑IT services?
Yes. Although it originated in ITSM, the principles of clear service definition, measurement, and governance are applicable to any repeatable service offering, such as facilities management or HR support.
What tools support a Service Definition System?
Various tools can be employed, including ITSM platforms (e.g., ServiceNow, BMC Remedy), CMDB solutions, and custom metadata repositories. The choice depends on organizational needs and existing technology stacks.
