Now in its fourth version, ITIL is one of the leading frameworks for IT service delivery. It outlines best practices for the most common ITSM processes along with the general principles of effective service delivery.
ITIL-certified professionals have the skills and expertise to select, plan, deliver, and maintain IT services that deliver value to the wider organization.
Made up of 34 distinct practices, ITIL offers a roadmap for delivering value to service users across all aspects of business IT.
ITIL stands for Information Technology Infrastructure Library. Designed with the purpose of achieving maximum alignment between IT teams and wider organizational goals, it’s a framework that outlines best practices for delivering services in an enterprise context.
As well as providing IT departments with a playbook for planning and implementing services, ITIL’s creators, AXELOS, provide certification for colleagues to prove their familiarity with the systematic approach to service delivery.
In its current version, ITIL outlines 34 distinct processes split across three lifecycle stages. The goal here is to provide an adaptable, scalable, and customizable playbook for implementing each of these core IT services.
As such, each process provides a series of constituent actions, triggers, inputs, and outputs. Each of these processes is defined in more detail later in this resource.
ITIL’s primary goal is to create predictable IT environments that provide the maximum value to service users, whether these are customers or colleagues.
More specifically, ITIL is grounded in the following seven guiding principles:
The fourth version of ITIL was published in 2018. While most of the substantive information was carried across from previous versions, ITIL V4 also introduced some important changes in terms of terminology.
Specifically, ITIL V3’s 26 constituent processes were replaced with 34 practices in ITIL V4.
These are divided into three categories.
Despite the change in name to practices, we can still effectively think of these as generic business processes.
As such, we’ll be using the terms practices and processes interchangeably.
All processes within ITIL are structured around what is known as the Service Value Chain. This is the basic outline that each of the constituent practices follows to enable IT teams to identify demand and facilitate value to service users.
The six stages of the Service Value Chain are as follows:
The 34 underlying processes within ITIL V4 are broken into the following three categories:
Let’s take a look at each category in more depth.
There are 14 distinct practices within the general management category. As noted, these relate to the IT team’s overarching service delivery rather than the granular details of individual services.
These are:
Strategy management involves setting goals for the ITSM team and identifying strategies to meet them. This helps the IT department identify the resources and services required to achieve our organizational goals, along with service delivery KPIs.
Strategy management includes:
Architecture management aims to provide an understanding of the all of the different elements that make up the organization and its IT services, along with the various ways that these relate to one another.
There are five key strands of architecture management:
Service financial management aims to ensure that financial resources are used as effectively as possible when delivering IT services, including a range of foreceasting, control, and administrative tasks.
The three key elements of service financial management are:
Workforce and talent management seeks to ensure that our organization has the right colleagues in the right roles across our service delivery teams. This includes everything from planning, recruitment, and onboarding to people management and performance reviews.
Effective workforce management is vital for maximizing service quality. By ensuring that we have the required skills, talent, and expertise across our IT team, we’re considerably better positioned to deliver quality internal services in a timely manner.
Continual improvement is the practice of retaining alignment between our IT services and wider business objectives, especially in the context of changing requirements or environmental factors.
Key aspects of the continual improvement process under ITIL include:
Measurement and reporting furnishes our ITSM team with the data they need to make informed decisions around service management, changes, and improvements. This involves gathering and analyzing relevant data around individual services and our IT capabilities as a whole.
The primary data objects that we’ll need to operationalize and measure include:
Risk management is how an organization identifies, mitigates, prevents, and handles risk, including in relation to finances, operations, security, and other resources. As such, risk management is critical to all other processes within ITIL.
The basic process for managing risks includes:
Information security management comprises all of our efforts to protect the information assets required for the organization to function. This includes maintaining the accuracy, integrity, confidentiality, and availability of data, including controlling storage, access, and exposure.
Information security management requires a range of policies, measures, and protocols to balance:
Knowledge management is the process of documenting, sharing, and codifying information about our IT services and leveraging it across the organization. This can be for the benefit of service-delivery colleagues or end users.
Knowledge is information that’s useful in a specific context, like how to action a defined workflow or resolve a particular problem. Therefore, knowledge management furnishes our team with the information they need to deliver services to colleagues.
Organizational change management deals with how changes are implemented within the organization. More specifically, it seeks to ensure that human aspects of change don’t undermine its success and effectiveness.
The goal is to ensure that all stakeholders affected by the change understand and accept it, including seeking buy-in, providing training, addressing concerns, formalzing approvals and authorization, and other strategies for removing barriers to change.
Project management is the process of monitoring and controlling the progress of projects so that they are delivered successfully. Within ITIL, a project is a temporary initiative that seeks to deliver agreed outputs according to an agreed business case.
Most ITSM projects follow either the Waterfall or Agile methodologies. In either case, the goal is to maintain operations while ensuring that new initiatives are implemented on time, within budget, and according to agreed specifications.
Relationship management is the ITIL process that relates to maintaining links with other stakeholders, including service users, vendors, and customers. The goal is to ensure that stakeholders’ needs are understood so IT teams can deliver value.
The core of relationship management within ITIL is facilitating structured communications between the IT team and stakeholders, as well as logging and learning from interactions. For instance, within complaints or escalation workflows.
Supplier management handles the performance of external stakeholders and partners, including vendors or contractors. Specifically, this ensures that required products and services are delivered effectively while also seeking to minimize associated risks and financial costs.
We can consider this at two levels:
Portfolio management is all about ensuring our IT team provides the right mix of services and other capabilities to meet the needs of the organization, while also handling the overall resource allocation relating to these.
There are three key kinds of portfolios we must deal with here:
Next, we have ITIL processes that fall under the category of service management. There are 17 practices under this umbrella, dealing with the more granular needs of specific services.
These are:
Service design is the practice of devising services and products that meet the needs of end-users based on the available resources. This includes outlining the required technical capabilities, skills, staffing, finances, and workflows for delivering a service.
While cost-effectiveness is naturally a priority, ITIL service design places heavy emphasis on customer and user experiences, helping to ensure high adoption rates and compliance with internal processes.
Service desk management is at the core of how users access internal services. Service desks provide a single point of contact between service agents, especially for submitting information about incidents, issues, and service requests.
An effective service desk requires the skills, technical capabilities, and workflows to:
Service level management relates to how we measure the quality of individual services. This requires us to define business-level targets against which our efforts can be measured. The goal is to provide end-to-end visibility into the success and value provided by our services.
Effective service level management requires:
Service request management is the process of facilitating access to services. This means enabling users to submit requests to initiate defined service workflows. IT teams can then determine how to proceed based on requirements, business rules, and resource availability.
Service requests can relate to:
Service validation and testing are performed to confirm that new or altered processes and services meet their requirements. Validation verifies that the service in question is capable of providing the expected value to end users.
Testing can come in a number of forms, including:
IT asset management comprises all of the workflows and tasks required to furnish our colleagues with the IT tools that they need to carry out their daily work. This includes laptops, desktops, phones, peripherals, software, data, network infrastructure, accessories, and more.
Asset management requires us to account for a wide range of workflows, including:
Monitoring and event management involves proactively seeking to identify changes in our services ecosystem. IT teams define and set up monitoring for events, including triggering notifications and logging the details when an event occurs.
As such, event monitoring and management requires a combination of the following:
Problem management is the ITIL practice that’s concerned with preventing and mitigating the impact of incidents. A problem is anything that has caused or has the potential to cause an incident.
Problem Management requires both reactive and proactive initiatives, including:
Release management relates to how we implement new services and capabilities, or changes to existing ones. While releases are synonymous with software, we must also be cognizant of the procedural, infrastructure, training, and delivery aspects of new services.
Within ITIL, release management requires a holistic approach, including:
Service catalog management aims to provide a centralized, accessible repository of information surrounding our IT services and how users can access them. Specifically, catalog management means keeping this up to date with changes to our ITSM offering.
Importantly, different kinds of stakeholders might have distinct requirements in terms of specific services and the data exposure that’s appropriate for them. Therefore, we can consider providing distinct views for:
Service configuration management handles information relating to configuration items (CIs). A CI is any element that’s required in order to deliver a service, including software tools, packages, and modules, as well as hardware, infrastructure, and devices.
Configuration management involves maintaining information relating to all CIs, as well as how these relate to one another within services. Typically, we’ll require rely on a dedicated configuration management database and admin tools to manage this.
Continuity management aims to ensure that key capabilities remain in place in the event of major incidents or disasters. These can include cyberattacks, major damage, natural disasters, supply chain failures, geopolitical events, or other crises.
Managing continuity requires our IT team to:
Availability management refers to the process of ensuring that services deliver the agreed functionality and value to users. In this context, availability means providing defined functionality when required.
The specific process of managing availability includes:
Business analysis involves understanding the underlying pain points and problems that our IT services must solve in order to identify the appropriate solutions. In other words, this means taking an empirical approach to establishing how our ITSM efforts can provide value.
Therefore, business analysis typically includes:
Capacity and performance management is tasked with ensuring that our IT service delivery keeps pace with the demand for services. The goal is to cost-effectively deliver solutions at a scale that’s appropriate to the needs of the business.
To achieve this, the following actions are typically required:
Change control refers to the process of authorizing changes that will affect our IT services. This also comprises determining the risks and impact associated with changes and scheduling any required actions to implement them.
Change control is distinct from change management in that it deals with discrete services rather than wider organizational change. This can be clustered into:
Incident management aims to minimize the impact on IT services and the wider business when incidents occur. We can define an incident as any unplanned event that interrupts or impacts the quality of services, such as data loss, server outages, cyber-attacks, or natural disasters.
Depending on the severity of the event, incident responses can take a variety of paths:
Technical management processes within ITIL relate to specific technical capabilities. More specifically, the priority here is transitioning IT teams away from thinking in terms of technical solutions and toward framing these as IT services.
The three constituent practices here are as follows.
Deployment management deals with moving CIs to live environments. This could be hardware, software, documentation, new processes, or any other elements of our IT service delivery. The goal is to provide a smooth, incident-free transition when implementing changes.
A wide variety of strategies can be employed for managing deployments, such as:
Infrastructure and platform management handles the organization’s network infrastructure, hardware, and wider IT environment. This comprises a range of monitoring, planning, maintenance, and other lifecycle management workflows.
This relates closely to capability and performance management, with organizational infrastructure playing a key role in facilitating the adoption of new technologies. For instance, machine learning, chat bots, cloud cloud computing, and more.
Software development and management is the practice of furnishing business teams with software tools that meet their requirements, as well as ensuring IT rules are adhered to across auditability, compliance, cost controls, maintainability, and integration.
This practice can comprise a huge range of activities and workflows, dealing with both custom and COTS software tools, such as:
