What Does DevOps Have to do With Agile?
One of the questions I commonly get asked at the workshops we run is “What’s the connection between Agile and Devops?” or vice-versa.

One of the questions I commonly get asked at the workshops we run is “What’s the connection between Agile and Devops?” or vice-versa. My usual tactic is to let the workshop attendees argue that one out amongst themselves. Firstly, because it’s quite an emotive question, so it gets people chatting, and secondly because I’m always keen to hear what other people’s opinions and experiences are.
Here are a few of the things I’ve heard from the workshop groups:
- “Devops is an evolution of Agile”
- “Devops is the missing link between agile development and operations”
- “Devops is a subset of Agile”
- “Agile is a subset of Devops”
- “What time are we having lunch?”
I’ve heard strong arguments in support of each one, and I’ve also heard people say there is no link between agile and devops (again, with a strong argument to support this opinion).
For me though, I like to think of devops and agile as complimentary. I also think devops is a key enabler for enterprise agility, and this is where things get a little murky. I don’t want to get into any great yak shaving exercise, but before we can describe the relationship between agile and devops, we really need to define what we mean by “agile”.
Agile development vs Organisational Agility
Agile development comes with many different frameworks, some more prescriptive than others, but they all share a certain number of core “agile“ features in common – namely that they embrace change, and are able to comfortably respond to it (ok there are plenty of other features in common, such as focus on customer value and working software etc, but I’m going to concentrate on the responsiveness to change for now).
Scrum, on the other hand, is a framework for helping you do agile software development, it has clearly defined team roles and a few rules you need to follow. But let’s be clear – Scrum is NOTagile. Don’t confuse the two!
Scrum is a framework for helping you do agile software development, doing agile software development helps you become agile
Now let’s take a deeper look in to what being “agile” is all about. It’s about being able to respond to changing conditions, changing market forces, changing requirements, and not only survive, but to succeed. “Change” is the arena in which agility thrives. So, to be agile you need to be able to react and respond to changes quickly. This is where the agile world and devops come together. Devops encourages closer and more meaningful collaboration between the business, developmentand operations, to help organisations deliver higher quality applications that can be deployed quicker, be maintained and monitored more easily, and provide fast and accurate feedback to the business. Without these key enablers, you’d be hard pressed to respond or react quickly to anything, let alone changing requirements, changing markets and changing technologies.
So in a nutshell, agility is all about the ability to embrace change, and succeed in a changing environment. Devops is one of the key ingredients to helping you achieve this.
Can you do agile software development without doing devops? Yes, of course you can, you could do Scrum, for example. But doing agile software development and being agile are two very different things.
So, now for the harder question: Can you “be agile” without doing devops?
Some might argue that this must be possible, because organisations have been agile for longer than devops has been around – to which I would respond by saying that the term “devops” may be relatively new, but the ethos behind it has been around for as long as agile has.
I imagine that under certain circumstances it may be possible to be highly agile and yet have an anti-devops culture, where there’s very little collaboration between the business, development and operations, but I’ve not actually come across it, if it does exist. In my experience, highly agile organisations from start-ups through to large enterprises, are embracing the principles behind devops whether they know it or not.
In summary, agile is NOT about sprints, it’s NOT bout stand-ups, it’s NOT about retrospectives or any of the following:
You can’t do agile, you can be agile, but you can’t DO it. You can “do” scrum, XP, Devops, TDD, BDD etc – these are explicit activities, unlike agile, which is more of a set of values and principles. You can perform all of the individual activities listed above, independently of any other. Sure, they certainly complement each other, but they can be done separately. The same can be said of agile software development and devops.
The relationship between devops and organisational agility is that one is an enabler for the other. The relationship between devops and Scrum, for example, is simply that they are both enablers for organisational agility, but they can also exist independently of each other.
