What is a DevOps Maturity Model and why is it important?

A DevOps Maturity Model is a framework designed to help organisations evaluate the extent to which they’ve adopted DevOps principles and practices.

These models outline a progression from early, ad hoc initiatives to fully optimised environments marked by automation, continuous improvement, and seamless cross-functional collaboration.

By understanding where they sit on this scale, companies can uncover bottlenecks, benchmark themselves against industry peers, and prioritise initiatives that will bring the highest ROI – be it through faster deployments, better collaboration, or improved product quality.

Key DevOps practices to follow

While there’s no single list of DevOps practices, some are widely considered foundational due to their direct impact on delivery speed, stability, and system reliability:

• Continuous Integration and Continuous Delivery (CI/CD)

Developers regularly merge code into a shared repository. Automated pipelines then build, test, and prepare code for safe and frequent deployment to production.

• Infrastructure as Code (IaC)

Infrastructure is defined and managed through code, enabling version control, consistency across environments, and rapid scaling.

• Automated Testing

Tests are run automatically throughout the pipeline to ensure code quality and reduce the need for manual validation.

• Monitoring and Observability

Systems are continuously monitored for performance and reliability, with insights collected to quickly detect and address issues.

• High Availability and Scalability

System architectures are designed to maintain uptime under varying loads and to scale resources efficiently based on demand.

These base practices form the foundation of most DevOps initiatives. Depending on the organisation’s needs and maturity, they can be complemented by more advanced practices like security automation, feedback loops, or configuration management.

There’s no one standard: different models, different strengths

Despite the popularity of maturity models in general, there is no single DevOps Maturity Model. Several established models exist, each offering a slightly different lens on what maturity looks like.

The most prominent framework, widely recognised and used by organisations like Google, Netflix, and Amazon, is the DORA Maturity Model, developed by the DevOps Research and Assessment team (part of Google).

Rather than focusing on practices, DORA looks at outcomes. It categorises organisations into four performance tiers – Low, Medium, High, and Elite – based on Deployment Frequency, Lead Time for Changes, Change Failure Rate, and Mean Time to Recovery. The model is regularly cited in the State of DevOps reports, which benchmark thousands of companies across industries and geographies.

Microsoft also offers a DevOps Maturity Model that evaluates an organisation across four key dimensions: culture, process, technology, and measurement. Its strength lies in its alignment with tools and practices in the Microsoft ecosystem, particularly for teams using Azure DevOps.

For large enterprises with complex infrastructure, the IBM DevOps Maturity Model provides a more detailed and structured approach. It places emphasis on continuous integration, delivery, testing, and monitoring – often tailored to heavily regulated industries and enterprise-scale challenges.

One of the most intuitive is the 5-Level DevOps Maturity Model, which defines five progressive stages:

• Initial
• Managed
• Defined
• Measured
• Optimised

This model is widely used due to its clarity and applicability for teams new to DevOps.

Each model offers different advantages. The DORA model stands out for ease of use and measurable business impact. The 5-Level model is intuitive for organisations starting out. Microsoft’s and IBM’s models are more structured and suited to specific ecosystems or enterprise environments.

How can organisations determine their current DevOps maturity level?

A practical starting point for assessing DevOps maturity internally is the DORA model, which focuses on four key performance metrics:

• Deployment Frequency – how often new code is deployed to production; it reflects the team’s agility.
• Lead Time for Changes – the time from code commit to production; it indicates the speed of delivery.
• Change Failure Rate – the percentage of deployments causing failures in production; this shows release reliability.
• Mean Time to Restore (MTTR) – how quickly the team recovers from incidents; it highlights resilience and incident response.

These metrics are straightforward to track using most modern CI/CD and monitoring tools and provide clear insights into the effectiveness of DevOps practices that are easy to benchmark.

For organisations looking to go further, external specialists can help conduct a more detailed analysis of how DevOps is applied across workflows, collaboration models, automation, and monitoring.

What are the benefits of reaching a high level of DevOps maturity?

Achieving high DevOps maturity offers a wide range of benefits, helping organisations stay competitive and responsive to market demands.

Key benefits include:

Faster adaptability to change

Continuous integration and deployment (CI/CD) practices allow businesses to quickly iterate and deploy new features, staying agile and responsive to market changes.

Improved collaboration

Breaking down silos between development and operations teams fosters better communication, leading to smoother workflows and enhanced productivity.

Faster deployment

DevOps automation of testing, integration, and deployment processes accelerates the release of new features and updates, reducing downtime and enhancing service delivery.

Enhanced product quality

Continuous monitoring and feedback loops catch and resolve issues early, resulting in higher-quality software development with fewer bugs and reduced maintenance costs.

Better alignment with customer needs

DevOps maturity enables quicker deployment of updates and services, helping businesses meet customer expectations and launch innovative products faster than competitors.

Operational efficiency

Automation reduces manual errors and optimises resource usage, ultimately lowering operational costs.

Improved scalability

DevOps practices like Infrastructure as Code (IaC) ensure seamless scaling, allowing businesses to handle increased load without manual intervention.

What challenges do businesses face when advancing in one of the DevOps Maturity Models?

As organisations move through a DevOps Maturity Model, they often encounter several challenges that hinder progress. Let’s look at them in more detail:

• Resistance to change: employees may be hesitant to adopt new tools or workflows, slowing the transition to a more collaborative and automated environment.
• Siloed teams: teams operating in isolated units can create communication barriers, limiting cross-functional collaboration and impeding DevOps implementation and success.
• Lack of automation: without automation, organisations face manual bottlenecks and delays, which can undermine DevOps culture and effectiveness.
• Insufficient training: DevOps requires specialised knowledge in areas such as CI/CD, infrastructure as code, and automated testing. Lack of training can hinder successful implementation.

Addressing these challenges requires strong leadership, effective change management, and a commitment to fostering a culture of collaboration and continuous improvement and learning.

Can a DevOps Maturity Model be customised for different organisations?

While maturity models offer a structured framework, their application must be tailored to each organisation’s size, structure, industry, and strategic goals.

For example, regulated industries like healthcare or finance may need to prioritise compliance and security integration at every stage of maturity. Meanwhile, startups or product-driven organisations might focus more on shortening feedback cycles and accelerating time-to-market.

Similarly, a small team might move more flexibly through early maturity stages, while a large enterprise will need alignment and coordination across multiple teams and departments.

DevOps maturity is about aligning practices with business goals. That’s why understanding the nuances of different models and applying them pragmatically is more valuable than rigid adherence to any single framework.
