DevOps vs. Agile
Both DevOps and agile are modern software development practices aimed at providing a framework to produce a part of a product, a launch or a release.
Understanding the difference
Although both DevOps and agile result in the development of software, they have different approaches, involve different groups and the departments and structure production differently.
The most important thing to know about DevOps versus agile is that they are not mutually exclusive. DevOps is culture, fostering collaboration amongst all participants involved in the development and maintenance of software. Agile can be described as a development methodology designed to maintain productivity and drive releases with the common reality of changing needs. Although DevOps and agile are different, when used together these two methodologies lead to greater efficiency and more reliable results.
An at-a-glance comparison
When evaluating DevOps versus agile, it’s important to understand the overall philosophy of each, where they’re similar and where they’re different, as well as how to integrate each within your team. DevOps and Agile are not mutually exclusive – you can incorporate aspects of each in your business. The information below will help you gain a broader understanding of the key similarities and differences between DevOps and agile.
DevOps is a software development practice that brings people, process and technology together to deliver continuous value. The approach is divided into planning and tracking, development, build and test, delivery, and monitoring and operations. DevOps is unique in that development, IT operations, quality engineering and security teams work together to create efficiency across all tasks involved in launching a new product, release or update.
DevOps philosophy and focus
Rooted in stability, consistency and planning, the DevOps culture seeks to identify new ways to improve and streamline processes. As a result, DevOps focuses on maximising efficiency, identifying programmable processes and increasing automation.
DevOps represents the intersections of development, operations and quality assurance. Cross-disciplinary teams unite and collaborate in the development and delivery of software.
- Continuous integration
- Continuous delivery
- Continuous deployment
Agile development is a delivery approach that relates to lean manufacturing. The fundamentals of agile centre around creating a working prototype or build amidst the realities of changing needs and requirements. Bridging the gap between the development team and the end-user, adaptability is a core attribute of agile, giving precedence to the needs of users and stakeholders over rigid plans.
Agile philosophy and focus
The fail-fast mindset of agile centres around adaptability and keeping pace with customer needs and expectations. Features are described as user stories, placing the focus on the individual user, what they need and why.
Agile development is specific to the development team, its productivity and its progress towards completing the project at hand. Development is completed in incremental sprints, and software delivery, deployment or ongoing maintenance of each release is managed by different teams
- Lean development
- Extreme programming
- Feature-driven development
How DevOps and agile work together
Both DevOps and agile offer a structure and framework that can speed software delivery. You do not need to choose between DevOps or agile. Instead, you can make use of both methodologies. Agile is strong on methods for organising work, such as via Scrum or Kanban, and DevOps drives a broader culture of delivering software faster and more reliably.
Instead of choosing between DevOps and agile, the question actually is how to practise both. When considering how to build a development practice with the best of DevOps and agile, here are some examples of key benefits and features that can help you create a highly optimised development environment.
Top features from DevOps
Broader scope, wider reach
DevOps addresses all stages of software development and delivery, seeking to make releases faster and more reliable.
A culture of reducing friction and fostering cross-functional teamwork can produce an improved work environment and more effective teams.
Efficiency from automation
The DevOps practice seeks to find opportunities to create programmable processes and automate workflows where possible, driving efficiency.
Top features from agile
Workflow productivity tools
Kanban, Scrum and other familiar planning tools from agile help track work, helping to organise requirements, tasks and progress.
Using sprints or other time-boxed production approaches help create a consistent development cadence.
Needs of the customer
Agile’s fail-fast, fail-early mentality helps provide a consistent feedback loop, bringing customer expectations to the forefront.
