What began in the 1980s as a collection of good practices for better managing IT organizations and serving IT customers has grown into a body of knowledge that, with more than two million certified ITIL practitioners, is used by more than 90% of Fortune500 organizations around the world. With the rapid pace of change in emerging technologies and customer needs, ITIL also continues to change. A recent AXELOS research program found “ITIL is becoming more and more important to enable Cloud and Big Data strategies.” The FORBES Insights: State of ITSM 2017 report also touts the value of ITIL, with 88% of IT executive respondents stating that ITSM is important to their digital transformation efforts. As a result, AXELOS and the greater community have embarked on the creation of ITIL 4.
ITIL v3, initially released in 2007 then updated in 2011, expanded upon version 2’s inclusion of 10 IT processes and a team or “function” (that of the Service Desk):
ITIL v3 introduced the concept of the IT Service Management Lifecycle along with five phases (Service Strategy, Service Design, Service Transition, Service Operations, and Continual Service Improvement); and publications were released for each of the five ITSM lifecycle phases.
ITIL v3 also introduced 15 additional processes organized according to these five phases, which were frequently used by IT organizations at the time to help provide IT services to customers. These additional processes included the following:
ITIL v3 also included details around additional teams or functions that support the work done as part of IT Operations, including Technical Management, Applications Management, and IT Operations Management, which included sub-teams for IT Operations Control and Facilities Management.
ITIL 4 is an evolution of ITIL v3 concepts, not a replacement. The good practices from previous versions of ITIL are still valid, however, the ITIL 4 publications have been updated to include additional modern practices and approaches for delivering valuable products and services to customers. The table below includes a summary of three key differences between ITIL v3 and ITIL 4:
|ITIL v3||ITIL 4|
|36 Processes, organized according to the ITSM lifecycle phases listed below.||34 Practices, each of which may include several processes, loosely organized into three practice types.|
|ITIL Service Management Lifecycle
||Service Value Chain (SVC):
|4 Ps of Service Design:
||4 Dimensions of Service Management:
In addition to the above, ITIL 4 introduces the following new concepts, which we’ll dig into in further detail below:
ITIL 4 also includes details on modern and emerging technologies like cloud computing, infrastructure as a service (IaaS), neural networks, natural language processing, machine learning, blockchain, etc. and weaves in concepts from Lean, Agile, Scrum, DevOps, and other modern ways of working. The topics included here will be further detailed in the following sections.
Is it really that simple? Did ITIL 4 just change the name from Process to Practice? It may appear so, simply seeing the mapping from one to the other between versions, but there are some key differences that need to be understood. First, ITIL 4 still uses the term process, and the definition has not changed. It is still defined as the activities involved in transforming inputs into defined outputs. So, what is a Practice, and how is it different?
To better understand this terminology change, think about one of the most well-understood ‘processes’ from ITIL v3: Incident Management. This is something every IT organization has been doing since there have been IT organizations. But is it just one way of transforming inputs into outputs? Or is it many distinct, dynamic workflows that are dependent upon the situation at hand? This is where ITIL 4 has elevated the idea of a “practice.” In ITIL 4, the Incident Management ‘practice’ represents all the organizational resources (people, information and technology, partners, and processes) that come together to perform the highly distinct and dynamic workflows involved in resolving Incidents.
For ITIL practitioners that are familiar with ITIL v3 processes, the table below provides a breakdown of the changes in terminology from ITIL v3 to ITIL 4.
As the below table shows, not only have there been changes to naming conventions, the Practices have been divided into three broad domains, based on where the practice originated:
General Management Practices have been adopted and adapted from general business management domains
Service Management Practices have been developed in service management and ITSM industries
Technical Management Practices have been adapted from technology management domains for service management purposes by expanding or shifting their focus from technology solutions to IT services
|General Management Practices||Service Management Practices||Technical Management Practices|
|Architecture Management||Availability Management||Deployment Management (previously named Release and Deployment Management)|
|Continual Improvement Management (similar to the ITIL v3 phase CSI)||Business Analysis||Infrastructure and Platform Management|
|Information Security Management||Capacity and Performance Management (previously named Capacity Management)||Software Development and Management|
|Knowledge Management||Change Enablement (previously named Change Control and Change Management)|
|Measurement and Reporting||Incident Management|
|Organizational Change Management||IT Asset Management (previously named SACM)|
|Portfolio Management (previously named Service Portfolio Management)||Monitoring and Event Management (previously named Event Management)|
|Project Management||Problem Management|
|Relationship Management (previously named Business Relationship Management)||Release Management (previously named Release and Deployment Management)|
|Risk Management||Service Catalog Management|
|Service Financial Management (previously named Financial Management)||Service Configuration Management (previously named SACM)|
|Strategy Management (previously named Strategy Management for IT Services)||Service Continuity Management (previously named ITSCM)|
|Supplier Management||Service Design|
|Workforce and Talent Management||Service Desk|
|Service Level Management|
|Service Request Management (previously named Request Fulfillment)|
|Service Validation and Testing|
Are you struggling with the elimination of the ITIL v3 Service Lifecycle? Why did ITIL 4 do away with it and replace it with the Service Value Chain (SVC)? The simplest answer is flexibility. In some ways (while not prescriptive), the Service Lifecycle caused many organizations and practitioners to feel fenced in by an ever-reiterating set of processes (and, unfortunately, several organizations were tempted to create silos to handle work in each area of the lifecycle).
The Service Value Chain, by its very nature, doesn’t represent any specific order of activities. All six of the SVC activities, or any combination thereof, may be undertaken to deliver products and services for customers, thereby creating value. Activities may be revisited at any point, and the depth to which an activity exerts influence on a single stream may change depending on the situation. How we combine and order these activities creates value streams. These streams describe the processes and workflows by which we set about doing work and getting products and services into the hands of our customers. Rather than what may have seemed like a single-stream set of processes in ITIL v3, ITIL 4 embraces a flexible model, which allows all areas of the organization to develop useful value streams, leveraging any number of practices and activities to co-create value with their consumers. Last, the Service Value Chain, along with other components like an organization’s guiding principles, requires system-level thinking and makes up an organization’s Service Value System — also a new concept in ITIL 4.
Some will recall the Four Ps (People, Processes, Products, and Partners) of Service Design from ITIL v3. These were four aspects that needed to be considered during the Design Phase of the Service Lifecycle. ITIL 4 expands on that notion, making the Four Dimensions of Service Management — namely Organizations and People, Information and Technology, Partners and Suppliers, and Value Streams and Processes — a linchpin in the planning, design, delivery, and management of every service. Each dimension lends vital insight for both service management and brings balance to the Service Value System itself. If any of these dimensions is not properly addressed, the connected product or service may become unavailable, not meeting customers’ expectations of quality and efficiency.
This concept replaces and expands upon the concept of the 4 Ps described in the ITIL v3 Service Design publication. It shows that there are several parts of an organization that need to be considered when delivering products and services; and that there should be a balanced focus between each of the four dimensions.
Note that ITIL 4 has moved Products—or more precisely, Products and Services—front-and-center as the final output of the 4 Dimensions. This makes sense, as each of these concepts is considered to co-create value for our customers. Additionally, Information and Technology has been added as a key component in this model. Information represents the knowledge necessary to manage services. While ITILv3 presented technology as important process enablers, ITIL 4 recognizes that technology itself is now being provided as a service, and how we manage our knowledge and information with and between systems is vital. Software, storage, infrastructure, even information security can now be consumed through third-party suppliers and partners, making this dimension a critical component of the overall Service Management framework as well.
In ITIL v3, value was described as something we created for customers. ITIL 4 takes a different perspective, putting more of a concentrated focus on the idea that service providers and service consumers must work together to create value, thereby co-creating it. Service providers cannot and should not create products and services (see diagram below) in a vacuum. Instead, we should actively collaborate with our customers on what is of value to them.
Within the ITIL 4 publication, a service is defined as:
There are also two types of key stakeholders defined within ITIL 4:
In some instances, the same person may serve in several roles. In other cases, different people may fill the various roles. As a Service Provider organization, it’s helpful to understand who fills each of these roles and what each wants and needs from us.
There are often multiple service relationships involved in providing products and services to customers; and a service provider for a consumer of that service may be a consumer of a service with a different service provider (as shown in the diagram below). The ITIL 4 Foundation publication provides an overview of the different types of service providers, including service customers and other stakeholders.
In ITIL 4, there is a much larger emphasis on enabling customer value; and value is now defined as:
In evaluating whether a product or service has value for a customer, they are looking at the outcomes (What does this product or service allow me to do? What costs or risks does this product or service remove?), not just the output of the work. ITIL 4 defines the difference between the two:
ITIL 4 also distinguishes cost from value. Where value is defined through the service consumer’s perception, cost is defined as:
There are two types of cost from a consumer perspective. First, there are costs that are removed from the consumer by the product or service. This might be costs associated with staff that has been outsourced, technology provided as a service (cloud services), etc. Second, there are those costs that are imposed on the consumer by the product or service. Examples may include training, network or storage utilization, procurement, etc. This is commonly referred to as what a consumer must ‘invest’ to consume a service. In the end, the advantages of using a service (the removal of costs and risks) need to outweigh the disadvantages (the addition of negative outcomes, costs, or risks).
Risk may also be defined as uncertainty of outcome. When assessing the value of a service, risk may be used in the context of measuring both negative and positive outcomes. So, we also describe two types of risk. The first are risks removed from a consumer by the service (positive outcomes). This might include hardware failure if the consumer is moving to a cloud model, or staff availability if a function is being outsourced. Risk may not be entirely eliminated, only reduced, but the consumer may consider such reduction sufficient to support the value proposition of the service. Second, there are risks imposed on the consumer by the service (negative outcomes). This might be realized as a data security breach of the service provider.
Unlike the release of ITIL v3, ITIL 4 has been iteratively released throughout 2019 and 2020. The 2-day ITIL 4 Foundation course, exam, and publication were released on February 28, 2019 – the advanced courses, exams, and publications were released in Q4 of 2019:
Each of the ITIL 4 advanced courses (CDS, HVIT, DSV, and DPI) are all three days in length with an exam at the end. Details on each of the different courses and exams are included below. Several of the ITIL 4 practices were also released by AXELOS in Q4 2019 and Q1 2020. Additional detail on each practice is also included below.
ITIL 4 materials, including additional details around the 34 Practices, will be more frequently updated than in prior versions and made available online for ITIL practitioners. Those involved in the development of ITIL 4 content are creating material that is:
The ITIL 4 certification path, similar to that of ITIL v3, has an ITIL 4 Foundation exam and associated certification. There are less ITIL 4 intermediate courses than in ITIL v3 (see diagram below), which now include three ITIL Specialist courses, an ITIL Strategist course, and an ITIL Leader course as follows:
ITIL 4’s Intermediate courses are each three days in length, and there is no recommended order in which to take the courses. Students that hold PMI’s PMP designation will earn 16 PDUs for the 2-day ITIL 4 Foundation course and 24 PDUs for each ITIL 4 intermediate course. Once you earn the three ITIL Specialist credentials and ITIL Strategist credential, you will automatically earn the ITIL Managing Professional (MP) designation. This is similar to how in ITIL v3, when a student passed the Managing Across the Lifecycle (MALC) exam, they automatically earned the designation of “ITIL Expert”. When a candidate earns the ITIL Strategist and ITIL Leader credentials, they will automatically earn the ITIL Strategic Leader (SL) designation. Note: The “ITIL Strategist” that is shown below and is included in both the MP and SL tracks is a single course, exam, and publication.
ITIL v3 will be retired in 2020. Those that hold the ITIL v3 Foundation certification and want to get certified in the current version of ITIL will need to take the ITIL 4 Foundation exam.
Those that hold 17 credits of ITIL v3 certifications will be able to take a 5-day ITIL Managing Professional bridge course and exam and bridge to the MP designation (which also earns you 40 PDUs). For those that hold some intermediate ITIL v3 certifications, but do not yet have 17 credits, will be able to take ITIL v3 courses and exams until mid-2020 and can still bridge to MP. Here’s a little more on how your existing ITIL v3 credits can translate to ITIL 4.
ITIL 4 does not have the designation called “ITIL Expert”. The equivalent to the ITIL v3 “ITIL Expert” certification is ITIL 4 “ITIL Managing Professional” or MP. There is an advanced certification entitled “ITIL Strategic Leader” or SL that can be obtained, if a candidate already holds the MP designation, by taking an “ITIL Leader: Digital & IT Strategy” 3-day course and passing the associated exam. ITIL 4 has an “ITIL Master” designation. Details on how to obtain the ITIL Master designation will (hopefully) be coming out later in 2020.
The ITIL 4 Foundation exam (closed-book) is similar in format and level of difficulty to that of ITIL v3. Here are the highlights:
60-minute time limit
40 multiple-choice questions
26/40 (65%) or higher is a passing score
4 question types:
For students looking to enroll in an ITIL 4 Foundation course, this is a 2-day offering with the in-class, paper exam taken at the end of the second day. Students that hold PMI’s PMP designation will earn 16 PDUs.
The closed-book ITIL 4 advanced course exams are as follows:
90-minute time limit
40 multiple-choice questions
Students must get at least 28/40 correct to pass (70%)
There are 3 question types:
In today’s digital and highly disruptive world, organizations must change how they work in order to remain relevant in their industries and to their customers. That’s where ITIL 4 can help. The new version includes a wealth of information on how the most successful organizations are working, along with details on emerging technologies (including, but not limited to, Artificial Intelligence and AIOps, Robotic Process Automation, Blockchain, Machine Learning, and Natural Language Processing) – with recommendations on how to best leverage them, as well as modern approaches to work including Lean, Agile (with details on Scrum, Kanban, and XP techniques), DevOps (Continual Integration / Continual Development (CI/CD), etc.).
For the first time, ITIL 4 also introduces several practices outside of traditional Service Management, including Organizational Change Management, Project Management, Business Analysis, Architecture Management, and Workforce and Talent Management. It is a comprehensive look at IT Service Management and the practices that matter most today.
