The key components of the ITIL 4 framework are the ITIL service value system (SVS) and the four dimensions model.
The ITIL SVS (Service Value System)
The ITIL SVS represents how the various components and activities of the organization work together to facilitate value creation through IT-enabled services. These can be combined in a flexible way, which requires integration and coordination to keep the organization consistent. The ITIL SVS facilitates this integration and coordination and provides a strong, unified, value-focused direction for the organization. The core components of the ITIL SVS are:
- The ITIL service value chain
- The ITIL practices
- The ITIL guiding principles
- Continual improvement.
The ITIL service value chain provides an operating model for the creation, delivery, and continual improvement of services. It is a flexible model that defines six key activities that can be combined in many ways, forming multiple value streams. The service value chain is flexible enough to be adapted to multiple approaches, including DevOps and centralized IT, to address the need for multimodal service management. The adaptability of the value chain enables organizations to react to changing demands from their stakeholders in the most effective and efficient ways. The flexibility of the service value chain is further enhanced by the ITIL practices. Each ITIL practice supports multiple service value chain activities, providing a comprehensive and versatile toolset for ITSM practitioners.
The ITIL guiding principles can be used to guide an organization’s decisions and actions and ensure a shared understanding and common approach to service management across the organization. The ITIL guiding principles create the foundation for an organization’s culture and behavior from strategic decision making to day-to-day operations. The ITIL SVS also includes governance activities that enable organizations to continually align their operations with the strategic direction set by the governing body. Every component of the ITIL SVS is supported by continual improvement. ITIL provides organizations with a simple and practical improvement model to maintain their resilience and agility in a constantly changing environment.
The four dimensions model
To ensure a holistic approach to service management, ITIL 4 outlines four dimensions of service management, from which each component of the SVS should be considered. The four dimensions are:
- Organizations and people
- Information and technology
- Partners and suppliers
- Value streams and processes.
By giving each of the four dimensions an appropriate amount of focus, an organization ensures its SVS remains balanced and effective. we will discuss in deep next about four dimensions.
