On the other hand, the Value Stream is a series of steps an organisation undertakes to create and deliver services and products to consumers. The Value Stream is different for every organisation and needs to be specified.
The new version of ITIL provides a generic reference model to be able to create Value Streams: this model is called Service Value Chain.
The Service Value Chain
The Service Value Chain is an operating model, which outlines the key activities required to respond to demand and facilitate value realisation through the creation and management of products and services. Each organisation will allocate the Service Value Chain according to their business needs. The SVC responds to the trigger, the question and the need of an organisation.
The six main activities of the ITIL Service Value Chain are:
- Plan
- Engage
- Design & Transition
- Obtain & Build
- Deliver & Support
- Improve
In reality, the SVC needs other elements in order to be completed. Even if these elements are not part of the chain: the trigger, or the question, is the need that the SVC responds to.
Every organisation will be able to define its own specific Value Stream starting from the reference Service Value Chain.
Value Stream
Different factors are included while creating the Value Stream, like:
- Structure of the organisation
- The team
- The competences
- The organisational culture
All above mentioned elements either influence or determine how the Value Stream is defined.
Specific roles and responsibilities, resources and tools will be defined within the Value Stream. The Value Stream will represent how the organisational model will be used to respond to a specific trigger, need or question.
While creating a Value Stream with the Service Value Chain as a base, it is advisable to start from the demand. That way the end result is always a value, regardless of the Value Stream that we are going to identify.
Other important facts about the Value Stream:
- The order of activities is not pre-established and can be different every time
- The Value Stream does not concern a single group but involves several teams
- The Value Stream activities do not only involve IT staff but also includes stakeholders
- Each activity of the Value Stream has specific support and stakeholder practices
In order to create Value Streams it is necessary to know the activities, define their priority and manage the possible involvement of external companies.
Conclusion: Service Value Chain and Value Stream
ITIL provides the Service Value Chain to identify the Value Streams. The organisation always starts from the Service Value Chain and uses this model to identify the specific Value Stream. Once an organisation has defined its Value Streams, it is easy to follow the activities and practices. It recognizes the stakeholders involved and the activities required to transform the need into something that generates value for everyone.
