As part of the Agile “family”, DevOps is often seen as strictly incompatible with any formal processes. Is there a place for ITIL in the post-DevOps world?
IT professionals are constantly seeking methodologies that can streamline software development processes, enhance team efficiency, and deliver value to customers. Two prominent frameworks that have shaped the IT landscape are ITIL and DevOps. While for some they might seem similar, understanding their unique strengths and potential for synergy is crucial for project managers, engineers, consultants, and their clients.
This article aims to showcase the differences and similarities between ITIL and DevOps, offering practical insights and educational background to help you determine which approach, or combination thereof, is suitable for your specific challenges.

First, let’s take a closer look at the two approaches to understand what are their main principles and when they prove themselves handy.
The Information Technology Infrastructure Library (ITIL) is a set of practices for IT service management (ITSM) that focuses on aligning IT services with the needs of businesses that invest in them. ITIL outlines processes and procedures for managing incidents, service requests, changes, and other aspects of the IT service lifecycle. With its roots dating back to the 1980s, ITIL has evolved through several versions, with ITIL 4 being the latest iteration, emphasizing a flexible, coordinated, and integrated system for effective service management.
The ITIL framework is built on five core volumes:
ITIL 4, released in 2019, introduced several new concepts and updated existing ones to align with modern IT practices. It emphasizes the importance of end-to-end value streams. Moreover, it introduced the Service Value System (SVS) and the Four Dimensions Model. These updates aim to make ITIL more flexible and adaptable to various organizational contexts and emerging technologies.
ITSM software designed to implement the ITIL framework can be extremely helpful in embracing this approach. For instance, Alloy Navigator incorporates key ITIL processes as automated pre-installed workflows. There’s no need to create them from scratch. The solution is able to handle specific operations from day one. Connect with Alloy Software sales team to learn more.
DevOps, which comes from connecting the words “development” and “operations,” is a practice that emphasizes the collaboration and communication of software developers and other IT professionals. It aims to automate and integrate the processes between software engineers and their teams so they can build, test, and release software faster and more reliably. Key principles include continuous integration/continuous delivery (CI/CD), the concept of Site Reliability Engineering (SRE), and breaking down silos. DevOps is also closely connected with Agile methodologies, which focus on iterative development and delivery.
The core principles of DevOps include:
DevOps practices often involve the use of various tools and technologies, such as version control systems (e.g., Git), containerization platforms (e.g., Docker), orchestration tools (e.g., Kubernetes), and infrastructure-as-code solutions (e.g., Terraform). These tools enable teams to automate many aspects of the software development and deployment process, reducing manual errors and increasing the speed of delivery.
ITIL predates DevOps, with the latter emerging as a response to the need for faster development cycles and more collaboration between developers and non-developers. While ITIL provides a structured approach to service management, DevOps offers agility in software delivery.
The comparison between DevOps and ITIL arises from their shared goal of improving IT services. Their use cases overlap in areas such as incident management and change management, but the perspectives vary.
Since both methodologies aim to improve the efficiency and effectiveness of software development, it’s important to understand how they approach these goals:
Despite these differences, there are areas where ITIL and DevOps can complement each other. For example, ITIL’s incident management processes can be enhanced by DevOps’ emphasis on automation and rapid response. Similarly, DevOps practices can benefit from ITIL’s structured approach to change management and service level agreements.
However, some professionals express skepticism about ITIL’s compatibility with DevOps’s fast-paced nature. Concerns often revolve around ITIL’s perceived rigidity and how it might suppress DevOps’s dynamic nature.
To effectively blend ITIL with DevOps, organizations can take practical steps to harmonize their processes and cultures. Here are some actionable strategies we recommend:
The integration of one set of guidelines with the other within an organization’s IT strategy has sparked considerable debate, with various concerns arising from their seemingly different philosophies. The discussion on Reddit has brought to light several crucial points that highlight the challenges faced when attempting to harmonize these two frameworks.
One of the most significant barriers to the successful implementation of ITIL alongside DevOps is the cultural clash between the two. ITIL’s roots in traditional IT service management have fostered a culture that is often perceived as bureaucratic and slow-moving. Its emphasis on formal processes, standardization, and control seem to not match with the DevOps approach. This cultural divide can lead to resistance within teams, as each side defends its approach to IT management.
The detailed processes and documentation requirements championed by ITIL are frequently seen as obstacles to the rapid development and deployment of DevOps. Critics argue that the process-heavy nature of ITIL can stifle the speed and flexibility that DevOps teams strive for. Simply put, DevOps advocates for “just enough” process to maintain stability, while prioritizing the ability to adapt and respond to changes quickly.
The contrast between ITIL’s focus on stability and risk management and DevOps’ encouragement of experimentation and iterative improvements further complicates their coexistence. ITIL’s structured approach is designed to minimize risks and ensure reliable IT services, which can act as a barrier to the fast-paced changes and innovation that DevOps seeks to implement. While DevOps may introduce certain risks through its rapid iteration, it is also the driving force behind faster innovation within the industry.
Adapting to the fluid and dynamic practices of DevOps can be challenging for practitioners who have long relied on the well-established procedures of ITIL. The resistance to change is not uncommon, as the predictability and familiarity of ITIL’s methodologies provide a sense of security. On the other side, DevOps advocates often regard ITIL as an outdated framework that is not able to keep up with the rapid pace of technological advancement.
Integration of DevOps processes into an ITIL-driven environment is a complex task. Organizations are tasked with finding a balance that leverages the strengths of both frameworks without compromising their individual benefits. While ITIL brings robust IT governance and control to the table, DevOps practices may sometimes neglect these aspects, leading to potential service management gaps.
The value of ITIL in the era of DevOps is a subject of ongoing debate. Some industry professionals think that ITIL’s structured approach to IT service management is still relevant and can coexist with DevOps by focusing on the strategic aspects of IT governance. However, the growing popularity of DevOps has shifted the industry’s values towards speed, collaboration, and automation, potentially overshadowing the benefits of ITIL’s structured methodologies.
Determining whether ITIL, DevOps, or a combination of both is suitable for a particular organization depends on their challenges and goals. ITIL is ideal for companies that require robust service management with clear processes and metrics. On the other hand, DevOps is suited for teams that need to accelerate software delivery without sacrificing quality or stability.
For practical application, consider the following scenario. When it comes to incident management, ITIL offers a structured approach, ensuring that cases are handled consistently. DevOps can complement this by introducing automation and collaborative tools that speed up resolution times. Another example is change management. ITIL provides a framework for assessing and approving changes to minimize disruption. DevOps practices can streamline change implementation through automated testing and continuous delivery pipelines.
When choosing what approach to focus on, it’s essential to maintain a balance that leverages the strengths of each without compromising their core principles. To determine the most suitable approach for your organization, consider the following factors:
