ITSM ITIL 4 The 7 Guiding Principles of ITIL 4: Think and work holistically

The four dimensions of ITIL 4® are ingredients needed to create high quality products and services which deliver value to customers:

The delivery and support of different services and products requires a different mix of ingredients. No ingredient can deliver value on its own, so a holistic perspective is required: consider all dimensions when designing and changing products and services. The ITIL 4 four dimensions model is a tool to ensure people consider all the ingredients and they don’t get too focused on just one area.

Consider the Four Dimensions of ITIL 4 When Designing Services 

ITIL 4 recommends that organizations map the activity involved in delivering their products and services as service value streams—the paths of activity required to create value for the customer Defining end-to-end value chains helps provide the holistic view that people who perform the activities need to see the bigger picture (this is one way ITIL 4 integrates the 7 Principles of Lean: See and optimize the whole). 

The four dimensions of ITIL prompt people to look beyond the traditional IT perspective of technology to consider the broader service ecosystem—all the moving parts which combine to create value for the customer.

Consider the Four Dimensions When Applying Change 

When it comes to the IT change management process, it’s important to remember that the four dimensions influence each other. A change to one will always influence the othersThe smallest change can ripple across the system, creating widespread disruption. According to Gartner Inc., “80 percent of unplanned downtime is cause by people and process issues” (versus poor design, hardware failures, and external factors). 

For example, when a process changes, the people who perform that process may need to change how they work. A process change may also impact the information and technology. A new process usually means new information is needed to run the process. Where processes are automated, a change in process will require a corresponding change in service automation.

Are the Four Dimensions in ITIL 4 the Same as the Four Ps in ITIL V3? 

The four dimensions of ITIL 4 are an evolution of the four Ps seen in ITIL V3 (People, Products, Processes, Partners). They have been revised to consider the broader aspects of the service ecosystem (and the way these aspects influence each other) to encourage a change in the way we think about service value streams. 

Organizations and People

The human aspect: The people doing and managing the work. 

The 7 Guiding Principles of ITIL 4: Collaborate and promote visibility

The organizations and people dimension sets out the people aspects of service management to be considered when designing, operating and changing service offerings. People include employees, managers, executives, customers, supplier employees, or anybody else who is involved in the creation or consumption of services. 

Key considerations of the organizations and people dimension are: 

  • Organizational structure: Are your organizational structures (hierarchies, teams, roles, and responsibilities) geared to enable value creation? Can activity be clearly mapped to roles? ITIL 4 brings new guidance on how IT people work together. For example, flat organizations which are oriented around the flow of value streams (horizontal) tend to perform better because their structure is optimized for flow efficiency (versus a hierarchy which is geared for resource efficiency).
  • Governance: Do your governance structures balance flexibility versus risk? Are people free to make decisions and adapt the way they work? 
  • CultureIs your culture collaborative? Are people focused on delivering value to customers, or operating processes and technologies? 
  • Communication: Do your communication practices support teams working together to deliver value? What is the potential impact on the customer if stakeholders fail to communicate? 
  • Capacity: Do you have enough people to support your practices/capabilities? Are human capacity bottlenecks slowing down value delivery? Do you need more people, or would automation and AI help?
  • Competence: Are your people trained to operate and manage services and value streams in an efficient manner? Where can weaknesses be remedied with education?
  • Interfaces: What are the face-to-face and digital touchpoints between teams? Do these support the flow of your value streams? 

Value Streams and Processes 

How the work happens. And why.

Value Streams and Processes introduces the new Service Value Chain which is central to ITIL 4. In ITIL V3, the service lifecycle structure established a linear flow—strategy, design, transition, operation, and CSI. The ITIL 4 service value chain model is more flexibleevolved to support linear flows and iterative approaches (such as Agile)

Confused About the ITIL 4 Service Value Chain? - service value chain

The service value chain is an operating model which helps you describe how a value stream (the delivery process of a service) flows across various activities from demand to supply. The ITIL 4 service value chain model is generic and flexible, enabling any combination of steps to support different patterns of delivery. Each service value stream (the chain of activity which outputs aoutcome for the customer) combines different types of activity in a different order. Unlike the ITIL V3 service lifecycle, it isn’t linear: a value stream can jump back and forth as necessary. Organizations should map a value stream for every product or service to provide a holistic picture of how value is created. 

The ITIL 4 Foundation volume provides examples of how the service value chain operating model supports creation of different types of value, including: IT incident response, resolving a software issue, creating an IT service, and the development of new software. 

When considering the value streams and processes dimensionthink about: 

  • What is the definition of value here? Why are we doing this?
  • Which steps are creating value and which steps are waste (e.g. add no value for the customer)? 
  • Which steps are (or could be) automated? 
  • Which steps are performed manually by a human being? 
  • Which steps are performed by a third party? 

Remember, focus on value, or there is a risk that waste activity will displace value-creating activity—and compromise your productivity. It’s waste that stops you from doing more with less.

Information and Technology 

How information and tools help create value.

In the Information Age, information (and technologies which store and process of information) are critical enablers of value delivery. Indeed, in many cases—like Google’s search engine—information is the value. When thinking about information and technology, we must consider two angles: How they support individual service value streams and how they support the broader service management capabilities which help you manage your service portfolio: 

  • What information do you need to create, reference, or change to deliver value? What are the inputs/outputs of each step in the value stream? What information outputs does the customer want? 
  • Which technology component make up the service? What processing, storagenetwork and digital interface components do you need to create and transfer value? 
  • What information do you need to support service management capabilities? What do you need to know about volumes of demand, capacity, infrastructure, operations, customer satisfaction, costs, and other aspects of service management to run an efficient service portfolio? 
    • PerformanceAre current suppliers performing as expected? Can they handle peaks in demand?  What technology do you need to support service management? Successful service management at enterprise scale is always underpinned by service management technology. What tools do you need to run an efficient and effective service portfolio? For example, CMDBprocess automation, a knowledge database, service catalog, queue management, event monitoring, reporting and analytics.Other aspects you need to consider are skills and security. Do you have the right people to build, maintain, secure and support the technology you are bringing in? For example, organizations launching new information services based on big data architectures are finding it difficult to find people with the right skills. Cybersecurity headlines continue to highlight the potential damage to brand reputation. Security should be “baked in” to a service at design stagenot simply applied as an afterthought. 

      Partners and Suppliers

      Thinking about the broader service ecosystem.

      Every organization is a provider and consumer of services—they need partners and suppliers to help deliver their own services. However, the breadth and depth to which organizations integrate suppliers into their value chains varies depending on in-house capabilities, sourcing biases, and regulatory requirements. 

      When considering the partners and suppliers dimensionthink about: 

      • Strategy: Which capabilities do you want to retain in-house, and what do you need to outsource to access specialist capabilities? 
      • Scarcity: Do you have people with the right skills, or do you need to use partners to fulfil certain capabilities? 
      • Cost: How does the cost of outsourcing compare to the cost of your in-house capabilities? 
      • Relationships: Do you have good relations with supplier representatives, including support people? Are they responsive to incidents and requests for change? 
      • Flexibility: Do your supplier contracts allow for quick and simple changes without penalties, or do they require renegotiation? 
  • Internal and external influences 

    Internal and external influences (see Figure 1) are a broad set of factors which influence how you run service management. These factors must be addressed in the design and operation of service value streams to ensure services fit into the broader context of your business and your industry. ITIL 4 uses the PESTLE framework to systematically address Political, Economic, Social, Technological, Legal, and Environmental factors. For example, political regulations like GDPR and HIPAA require particular ways of doing things to ensure consumers and their privacy are protected. 

    Balancing the four dimensions 

    Singular focus on any one dimension causes issues across other dimensions. The key to balancing the four dimensions is to consider all factors when designing services; not as an afterthought. When a service value stream changes, all four dimensions should be re-considered. If not, the value chain may become unstable. Considering all the factors when applying change will help you to maintain an equilibrium throughout the lifetime of a service.
