Each activity contributes to the value chain by transforming specific inputs into outputs. The inputs could be demand from outside the value chain, or outputs of other activities, while the transformation is facilitated by ITIL practices, undertaken using internal or third-party resources, processes, skills, and competencies.

No service, practice, process, department, or supplier stands alone. The outputs that the organization delivers to itself, its customers, and other stakeholders will suffer unless it works in an integrated way to handle its activities as a whole, rather than as separate parts.

Taking a holistic approach to service management includes establishing an understanding of how all the parts of an organization work together in an integrated way (remember the four dimensions of service management?), including having an end-to-end visibility of how demand is captured and translated into outcomes. In a complex system, the alteration of one element can impact others and, where possible, these impacts need to be identified, analysed and planned for.

To apply this principle successfully, consider this advice:

Recognize the complexity of the systems

Collaboration is key to thinking and working holistically

Where possible, look for patterns in the needs of and interactions between system elements

Automation can facilitate working holistically

Value Streams & Processes

The value streams and processes dimension is concerned with how the various parts of the organization work in an integrated and coordinated way to enable value creation through products and services. This dimension defines the activities, workflows, controls and procedures needed to achieve agreed objectives. What matters in service management is that an organization establishes an operating model that that effectively organizes the key activities needed to manage products and services.

Value streams

A value stream is defined as a series of steps an organization undertakes to create and deliver products and services to consumers.

Structuring the organization’s service and product portfolios around value streams allows it to have a clear picture of what it delivers and how, and to make continual improvements to its services. By mapping its value streams, an organization can identify what is critical, what introduces waste and what can be improved upon.

Processes

A process is defined as a set of interrelated or interacting activities that transform inputs into outputs.

Processes define the sequence of actions and their dependencies, as well as describe what is done to accomplish an objective. Processes are underpinned by policies and can be broken down further through procedures which outline what is done, when, and by whom.

Continual improvement encompasses all elements of the ITIL SVS. It involves aligning an organization’s practices and services with changing business needs, through the ongoing assessment and improvement of each element involved in the management of products and services. Continual improvement applies to the SVS in its entirety, as well as to all of the organization’s products, services, service components, and relationships, and is the responsibility of every individual involved in service management.

You need to use all of your resources as effectively and efficiently as you can. This means that you should automate wherever you can, and use people only for tasks that can’t be automated. It also means that you need to think carefully about what you can automate and about the circumstances where only a person will do; and about simplifying those processes you do decide to automate to eliminate wasteful or inefficient steps.

You should always optimize the work BEFORE you automate it, as automating something that is inefficient or ineffective may just result in you doing the wrong thing faster!

IT asset is any financially valuable component that can contribute to the delivery of an IT product or service. The scope of IT asset management typically includes all software, hardware, networking, cloud services, and client devices

Emergency changes. These are changes that must be implemented as soon as possible; for example, to resolve an incident or implement a security patch. Emergency changes are not typically included in a change schedule, and the process for assessment and authorization is expedited to ensure they can be implemented quickly. As far as possible, emergency changes should be subject to the same testing, assessment, and authorization as normal changes, but it may be acceptable to defer some documentation until after the change has been implemented, and sometimes it will be necessary to implement the change with less testing due to time constraints. There may also be a separate change authority for emergency changes, typically including a small number of senior managers who understand the business risks involved.”

The key inputs to the SVS are opportunity and demand. The output of the SVS is value delivered by products and services. Opportunity refers to options or possibilities to add value for stakeholders or otherwise improve the organization
