The context of ITIL, with the release of ITIL 4 is now much bigger, with an emphasis on the business and technology world, how it works today, and how it will work in the future with Agile, DevOps and digital transformation.
Lifecycle to Service Value System
ITIL has evolved beyond the delivery of services to providing end-to-end value delivery. ITIL 4 is now centred around a service value system (SVS).
The central element of the SVS is the Service Value Chain, an operating model which outlines the key activities required to respond to demand and facilitate value creation. Sequences of these activities are known as value streams, of which the v3 Service Lifecycle is one such example.
Processes to practices
ITIL 4 refers to practices, where previous versions had referred to processes. A practice is a set of organizational resources designed for performing work or accomplishing an objective. Thus, practices comprise not just processes and procedures, but also people, skills, partners and suppliers, information, tools, and so on. There are 34 practices in ITIL 4.
The ITIL guiding principles, first introduced in ITIL Practitioner, are at the core of ITIL 4.
The ITIL guiding principles are:
- Focus on value
- Start where you are
- Progress iteratively with feedback
- Collaborate and promote visibility
- Think and work holistically
- Keep it simple and practical
- Optimize and automate
To support a holistic approach to service management, ITIL also defines four dimensions that collectively are critical to the effective and efficient facilitation of value for customers and other stakeholders in the form of products and services. The four dimensions represent perspectives which are relevant to the whole Service Value System.
Other ways of working
ITIL 4 will reflect other frameworks and integrate with new ways of working including Agile, DevOps, Lean, IT governance and Leadership.
