We often refer to IT Service Management (ITSM) and IT Infrastructure Library (ITIL®) in the IT support domain. While they are closely related, it's essential to understand their characteristics, similarities, and differences. Understanding the relationship between ITSM and ITIL helps organisations choose the right support approach, tailor their practises, and leverage industry best practises to enhance IT service delivery. Spoiler alert! Neither one stands alone. They were meant for each other.
Before we get into the technical definitions, differences and overlaps between ITIL and ITSM, let's use the restaurant business as an analogy. ITSM is the restaurant operation; ITIL is a renowned cookbook.
The restaurant (ITSM) is the entire operation — it involves not just cooking, but also menu planning, sourcing ingredients, serving customers, maintaining the dining area and kitchen, and so forth. It's all about providing a comprehensive service to the customers (the organisation), from the moment they walk in the door to the moment they leave.
Now, to ensure that this service is delivered efficiently and successfully, the restaurant might refer to a renowned cookbook (ITIL). This cookbook doesn't tell the restaurant what dishes to make, but it offers best practises — recipes, techniques, presentation tips, etc. — that can guide the restaurant in providing a top-notch dining experience. The restaurant might not use every recipe, but the guidance helps shape the menu and the cooking techniques to ensure customer satisfaction.
Just as the restaurant could technically operate without the cookbook (though perhaps not as effectively), ITSM can exist without ITIL. However, the cookbook (ITIL) could never exist without the concept of the restaurant (ITSM). They are distinct concepts, but ITIL is designed to support and enhance ITSM.
Understanding IT Service Management (ITSM)
IT Service Management (ITSM) refers to a set of practises, policies, and processes designed to efficiently and effectively deliver IT (Information Technology) services to meet an organisation's and its customers' needs. The primary goal of ITSM is to align IT services with the overall business objectives and improve the quality of IT service delivery.
Frameworks and standards such as ITSM practises often guide ITIL® (Information Technology Infrastructure Library), and COBIT (Control Objectives for Information and Related Technologies) drives the frameworks and standards such as ITSM and ITIL.
ISO/IEC 20000 and ITSM
ISO/IEC 20000, often called ISO 20000, is the international standard for IT Service Management. Individuals may use ISO/IEC 20000 certifications to demonstrate their expertise in implementing and auditing IT Service Management systems.
The benefits of ISO 20000
ISO 20000 can help any organisation benchmark its ITSM, improve its services, demonstrate an ability to meet customer requirements, and create a framework for independent assessment:
- ISO 20000 may offer a competitive differentiation by demonstrating reliability and high-quality service.
- Given that many public sector enterprises demand proof of ISO 20000 compliance from their IT service suppliers, it could open doors to important markets.
- Assures clients that their service requirements meet an agreed level of quality.
- Encourages a culture of continuous improvement by allowing service providers to track, evaluate, and compare their service management procedures and offerings against a set standard.
- ISO 20000 compliance dives down the costs of conformance to many regulations, including the PCI DSS and Sarbanes-Oxley (SOX).
- ISO 2000 standards help leverage ITIL Practises to optimise resources and practises.
Understanding ITIL
ITIL is a best-practise framework or set of best practises that guide ITSM. ITIL does not prescribe what to do; it guides IT organisations in best practises.
ITIL is not equal to ISO 20000
It is important to note that ISO 20000 is a standard, while ITIL is a best practise, not a standard. ISO 20000 is for the business, while ITIL is for individuals.
Best practises are meant to work together ITIL/COBIT/ISO 20000
| ITIL | COBIT | ISO 20000 | |
|---|---|---|---|
| Description | Best Practises for IT Service Management | Business Framework for Governance and Management of Enterprise IT | International Standaard for IT Service Management Requirements |
| Market View | ITIL's main focus is on internal IT practises. The latest version emphasises the customer and value. | COBIT's primary focus is on IT governance and IT competence. The latest version emphasises enterprise IT, which has a broader scope than previous versions. | ISO 20000 main focus is on Certification Achievement to demonstrate compliance with the international standard. |
| User Group | International IT operation personnel | IT audit and compliance personnel | External IT service provider |
| Purpose | Defining the Internal IT Service Management (ITSM) practises. | Defining the audit and compliance requirements for IT. | Demonstrating the organisation meets international standards. |
Examples of ISO 20000 standards and the corresponding ITIL best practise
ISO 20000 is an international standard that specifies the requirements for an organisation's Information Technology Service Management (ITSM) system. It provides guidelines for establishing, implementing, maintaining, and improving IT Service Management processes within an organisation. Here are some — by no means complete — examples of ISO 20000 standards and supporting ITIL Practises:
| ISO Number | ISO Definition | Guidance Focus | ITIL Practises |
|---|---|---|---|
| ISO 20000-1;2018 | Part 1: Service Management system requirements. | A core standard that outlines the requirements for an organisation. |
|
| ISO 20000-2:2019 | Part 2: Guidance on the application of Service Management systems. | How to apply the requirements of ISO/IEC 20000-1 in the context of an organisation's specific IT Service Management needs. |
|
| ISO 20000-3:2019 | Part 3: Advice on how to use ISO 20000-1 and define its scope. | Defining the scope of the IT Service Management system and its applicability to different parts of an organisation. |
|
| ISO 20000-4:2020 | Part 4: Service Management system resilience. | Ensuring the resilience of the IT Service Management system, allowing organisations to recover from incidents and maintain service continuity. |
|
| ISO 20000-5:2019 | Part 5: Exemplar implementation plan for ISO 20000-1. | This standard provides an exemplar implementation plan to help organisations effectively implement ISO/IEC 20000-1. |
|
| ISO 20000-6:2020 | Part 6: Criteria for organisations that audit and certify service management systems. | This standard sets out the requirements for bodies providing audit and certification of IT Service Management systems, ensuring consistent and reliable certification processes. |
|
| ISO 20000-7-2019 | Part 7: Guidance on the integration and alignment of Service Management and system management. | Guidance on integrating and aligning IT Service Management with other management systems, such as ISO 9001 (Quality Management) and ISO/IEC 27001 (Information Security Management). |
|
These standards collectively form the ISO 20000 series, providing organisations with a framework to enhance the quality and efficiency of their IT Service Management practises, resulting in improved service delivery and customer satisfaction. There are 34 ITIL Practises to assist in ISO 20000 compliance.
Commonalities between ITSM and ITIL
ITSM and ITIL share several commonalities in their approach to IT Service Management:
- They prioritise delivering high-quality services
- They focus on customer satisfaction and continuous improvement
- They advocate a practise-oriented approach
- They emphasise alignment with business objectives
- They promote a service lifecycle perspective
- They support IT governance and compliance
Understanding these commonalities sets a strong foundation for organisations to implement ITSM and leverage ITIL Practises effectively to promote ITSM standards.
The shared objective of delivering high-quality IT services
ITSM and ITIL share a common goal of providing high-quality IT services that meet the needs and expectations of customers. They emphasise the importance of understanding customer requirements, ensuring service availability, and continuously improving service delivery processes.
A focus on customer satisfaction and continuous improvement
Customer satisfaction is a crucial driver for both ITSM and ITIL. They advocate for a customer-centric approach, actively engaging with users to gather feedback and incorporating it into service improvement initiatives. Additionally, both frameworks promote a culture of continuous improvement, encouraging organisations to regularly assess their processes and make necessary adjustments to enhance efficiency and effectiveness.
Emphasis on a practise-oriented approach and best practises
ITSM and ITIL highlight the significance of adopting a practise-oriented approach to manage IT services effectively. They provide guidelines and best practises for defining, implementing, and optimising practises across the service lifecycle. By following these practises, organisations can streamline operations, enhance service quality, and ensure consistent delivery of IT services.
Alignment with business objectives and strategies
Both ITSM and ITIL recognise the purpose of IT. As the shortened name suggests, the goal is to provide the information the business requires to make timely and accurate business decisions and to ensure that the data is available, accurate, and protected.
ITSM and ITIL emphasise aligning IT services with the organisation's business objectives and strategies. They stress the importance of understanding the business requirements and ensuring that IT services contribute to achieving those objectives. This alignment enables IT to act as a strategic partner to the business, supporting its growth and success.
Adoption of a service lifecycle approach
ITSM and ITIL frameworks promote a service lifecycle approach, which involves defining, designing, transitioning, operating, and improving IT services. This holistic perspective ensures that services are managed comprehensively from inception to retirement. It also facilitates better planning, risk management, and decision-making processes.
ITIL 4 introduced a four dimensions approach to service management. Together, they provide a comprehensive approach to service management, which is vital for facilitating value creation for consumers in the form of products and services:
- Organisation and people
- Information and technology
- Partners and suppliers
- Value streams and processes
Support for IT governance and compliance
ITSM and ITIL frameworks provide guidance and support for IT governance and compliance requirements. They emphasise the need for establishing controls, documenting policies and procedures, and ensuring adherence to regulatory standards. By following these practises, organisations can mitigate risks, enhance security, and maintain compliance with industry-specific regulations.
Differences between ITSM and ITIL
While ITSM and ITIL are closely related, there are distinct differences between the two frameworks that organisations should understand. Exploring these differences helps determine which approach best suits their needs and goals.
Scope and breadth of coverage
ITSM focuses on the end-to-end delivery of IT services and includes various frameworks, methodologies, and practises. ITIL refers to best practises and guidelines for IT Service Management. ITIL provides detailed practises and recommendations for specific areas such as Incident Management, Change Enablement, and Service Level Management. ITIL never mandates but suggests following particular procedures to achieve what is best for the business and customers.
Relationship and dependency between ITIL and ITSM
ITIL is a subset of ITSM. It is a specific framework within the broader ITSM framework. ITIL provides clear guidelines and practises that organisations can adopt as part of their ITSM strategy. ITSM allows organisations to incorporate other frameworks or practises based on their requirements. For example, ISO 27001 is part of ISO 27000 family of standards that provides guidelines and best practises for information security management systems. ITIL does not prescribe which one to choose, only that a business should choose the one that fits their strategy and business requirements.
Flexibility and customization options
ITIL, being a well-defined framework, provides organisations with a structured approach to IT Service Management. It offers a standardised set of practises and policies that have proven effective in many organisations. However, this standardised approach may only sometimes align perfectly with the unique needs of every organisation. ITSM, being a broader concept, allows organisations to customise and adapt their IT Service Management approach based on their specific requirements and organisational context.
Certification and training programmes
ITIL has a well-established certification programme providing individuals with credentials at different levels, such as ITIL Foundation, ITIL Managing Professional, ITIL Strategic Leader, and ITIL Master. These certifications validate the individual's understanding and knowledge of ITIL Practises.
On the other hand, ITSM (ISO 20000) certifications are typically broader in scope (i.e., external business audit), covering various aspects of IT Service Management beyond just ITIL. ITSM certifications often encompass a more comprehensive range of frameworks, methodologies, and best practises related to IT Service Management.
Focus on maturity and organisational readiness
ITSM frameworks often emphasise assessing an organisation's IT Service Management maturity level and providing guidance on improving it. They focus on building a robust IT Service Management system that aligns with organisational goals and evolves. ITIL, within the ITSM context, guides organisations toward higher maturity levels by providing best practises for each stage of the service lifecycle.
The complementary nature of ITSM and ITIL
How ITIL aligns with ITSM principles
ITIL, as a specific framework within the broader concept of IT Service Management (ITSM), aligns closely with ITSM principles. ITIL provides detailed best practises and guidelines for various aspects of IT Service Management, such as Incident Management, Problem Management, Change Enablement, and Service Level Management. These Practises complement the broader ITSM framework by offering specific recommendations and processes that organisations can adopt to enhance their IT service delivery.
Leveraging ITIL within ITSM frameworks
Many organisations choose to incorporate ITIL Practises within their overall ITSM approach. By leveraging ITIL's best practises, organisations can benefit from the knowledge and experience accumulated through years of industry practise. ITIL provides a standardised set of 34 Practises and procedures that have proven effective in many organisations, enabling organisations to streamline their IT Service Management efforts and improve efficiency.
Organisations that have adopted ITSM frameworks and incorporated ITIL Practises have reported significant improvements in service quality, customer satisfaction, operational efficiency, and costs. These case studies highlight the value of combining the broader principles of ITSM with the specific guidelines and best practises offered by ITIL.
For example, an organisation may implement an ITSM framework to establish a comprehensive service management system, defining practises, roles, and responsibilities across the service lifecycle. Within this framework, they can integrate ITIL Practises such as Incident Management, which provides standardised procedures for handling and resolving incidents promptly and effectively. Organisations can create a cohesive and efficient IT Service Management ecosystem by combining the broader ITSM principles with specific ITIL guidance.
The complementary nature of ITSM and ITIL allows organisations to benefit from the strengths of both approaches. ITSM provides a flexible framework that encompasses the entire IT Service Management landscape. At the same time, ITIL offers specific best practises and guidelines organisations can adopt to optimise their service management practises. By combining the two, organisations can create a robust and tailored IT Service Management strategy that aligns with their unique requirements, fosters continuous improvement, and ensures the delivery of high-quality IT services.
It is important to note that while ITIL offers valuable guidance, organisations can incorporate other frameworks or practises that align with their needs and goals. The ultimate goal is to create an IT Service Management approach that maximises efficiency, meets customer expectations, and drives business success.
Choosing the right spproach: ITSM, ITIL, or both?
Factors to consider when selecting an IT management framework
When determining the most suitable approach for IT Service Management, organisations should consider various factors:
- Organisational goals and requirements: Assess the organisation's specific goals, priorities, and needs. Consider factors such as the organisation's size, industry regulations, and the complexity of IT infrastructure.
- Maturity level: Evaluate the organisation's current IT Service Management practises maturity level. Determine whether there is a need for foundational practises or if the organisation is ready for more advanced frameworks. There are 34 ITIL 4 Practises, all with specific organisational values. When determining maturity level, there are better options than avoiding some Practises.
- Resource availability: Consider resources, including budget, expertise, and time. Implementing a comprehensive IT Service Management framework requires investment and commitment, so assessing resource availability and planning is essential.
- Industry standards and compliance: Consider any industry-specific standards, regulations, or compliance requirements. Ensure that the chosen approach aligns with these standards and helps the organisation meet its compliance obligations.
Industry-specific requirements and standards
Different industries may have specific requirements when it comes to IT Service Management. For example, the healthcare industry may have unique regulations regarding patient data privacy, while the financial sector may have stringent security and risk management standards. Organisations must consider these industry-specific requirements and choose an approach that can accommodate and support them effectively.
Tailoring ITSM and ITIL to meet organisational needs
Organisations often find value in adopting ITSM and ITIL, as they are complementary and can address different aspects of IT Service Management. Organisations can leverage the broader principles of ITSM to establish a comprehensive framework that aligns with their goals and requirements. They can then incorporate specific ITIL Practises that best fit their needs.
By tailoring ITSM and ITIL to meet organisational needs, organisations can create a customised approach that combines the flexibility of ITSM with the specific best practises offered by ITIL. This approach allows organisations to maximise the benefits of both frameworks and create a robust IT Service Management strategy.
It's important to understand that the choice between ITSM, ITIL, or a combination of both is not mutually exclusive. Organisations can start with one approach and gradually incorporate elements from the other as they mature and their needs evolve. Flexibility and adaptability are vital in selecting the right pathway for IT Service Management.
Ultimately, the right strategy depends on the organisation's specific context, goals, and resources. Conducting a thorough assessment, involving stakeholders, and seeking expert guidance to make an informed decision is essential. The chosen approach should align with the organisation's objectives, optimise service delivery, contribute to overall business success, and fully supported by senior management.
The future of ITSM and ITIL
Trends and emerging practises in IT Service Management
IT Service Management (ITSM) constantly evolves to keep pace with technological advancements and changing business needs. Several trends and emerging practises are shaping the future of ITSM:
- Automation and Artificial Intelligence (AI): Automation and AI technologies are gaining traction in ITSM. Intelligent automation can streamline routine tasks, improve service efficiency, and enhance the customer experience by enabling self-service options, intelligent routing, and predictive analytics.
- DevOps integration: DevOps practises, emphasising collaboration and continuous integration and delivery, are becoming more integrated with ITSM. Integrating DevOps and ITSM enables organisations to achieve faster deployments, improved communication between development and operations teams, and more efficient incident resolution.
- Cloud-native ITSM: With the widespread adoption of cloud computing, organisations are embracing cloud-native ITSM solutions. Cloud-based ITSM platforms offer scalability, flexibility, and reduced infrastructure costs. They enable organisations to focus on service delivery rather than managing the underlying infrastructure.
- Shift towards customer experience: ITSM is increasingly emphasising the customer experience. Organisations are adopting a customer-centric approach, leveraging technologies like service portals, chatbots, and personalised self-service options to enhance customer satisfaction and engagement.
- Shift-Left service support strategy: These organisations realise that costs go up and customer satisfaction goes down when escalating (i.e., Level 1 to Levels 2 and 3) incidents are the norm. Shift Left means levels 2 and 3 objectives are to support Level 1 (i.e., Service Desk) by increasing resolution through training, knowledge tools, self-help, and problem management reducing recurring incidents.
The evolving role of ITIL in the digital era
ITIL, one of the most recognised frameworks for ITSM, plays a significant role in the digital era. The future of ITIL involves:
- Integration with Agile and Lean practises: ITIL is adapting to the Agile and Lean methodologies prevalent in modern IT environments. Organisations leverage ITIL Practises, specifically the Project Management Practise, while adopting Agile and Lean principles to ensure flexibility, speed, and responsiveness in service delivery.
- Emphasis on value co-creation: ITIL is evolving to focus on value co-creation between IT and business stakeholders. It recognises that IT is an enabler of business value and aims to align IT services with the strategic goals and outcomes of the organisation.
- Incorporation of emerging technologies: ITIL incorporates AI, machine learning, and automation into its Practises. This integration enables organisations to leverage these technologies to optimise service management practises, improve decision-making, and enhance operational efficiency.
- Continuous improvement and feedback loops: The future of ITIL involves an increased emphasis on continual improvement. ITIL encourages organisations to establish feedback loops, gather insights, and use metrics and data-driven analysis to drive ongoing improvement in service quality and performance.
Integration with other frameworks and methodologies
As ITSM continues to evolve, there is a growing recognition of the need for integration between different frameworks and methodologies. ITIL easily integrates with frameworks such as COBIT (Control Objectives for Information and Related Technologies), Lean IT, and Agile ITSM. This integration allows organisations to leverage the strengths of multiple frameworks, tailor their approach to specific needs, and create a comprehensive IT Service Management strategy.
By integrating ITIL with other frameworks and methodologies, organisations can benefit from each framework's best practises and guidance, resulting in a more holistic and practical IT Service Management approach.
Conclusion: Understanding ITSM and ITIL
Emerging technologies, customer-centricity, agility, and continuous improvement drive the future of ITSM and ITIL. As organisations embrace automation, cloud-native solutions, and a focus on customer experience, ITSM frameworks like ITIL adapt to incorporate these trends. The evolving role of ITIL involves integrating with Agile practises, emphasising value co-creation, including emerging technologies, and promoting continuous improvement. Integration with other frameworks further enhances the adaptability and effectiveness of ITSM strategies in meeting the dynamic demands of the growing digital landscape.
