How This Engineering Mindset Units You Up For Success

CALMS is a well-liked framework for assessing a company’s implementation of DevOps-based working practices. The mannequin was first printed inside The Devops Handbook.

Making use of the CALMS mindset to your work helps to set you up for DevOps success. You should use it to evaluate efficiency, id enchancment alternatives, and set up benchmarks towards neighboring groups and the broader trade. On this article you’ll study what the CALMS rules are and the way they’ll elevate your DevOps technique.

What Is CALMS?

CALMS units out 5 focus areas that high-achieving DevOps groups excel in:

  • Tradition – DevOps ought to be deeply ingrained in your group with sturdy assist in any respect ranges, from particular person builders to enterprise executives. Non-tech groups want to acknowledge the advantages of fast iteration and steady supply earlier than engineers can set up optimum workflows.
  • Automation – Handbook processes are labor-intensive, expensive, and error-prone. Utilizing automation to handle infrastructure and create deployments frees up groups to make extra significant enhancements to your merchandise.
  • Lean – DevOps and Lean methodologies go properly collectively. Eliminating bottlenecks, embracing fast failures, and counting on iteration as an alternative of prescriptive launch schedules will increase throughput whereas preserving high quality.
  • Measurement – Enhancements aren’t pulled from skinny air. The very best groups frequently measure and analyze information to examine what’s working and determine new alternatives. Adopting the DevOps philosophy inside current groups typically takes a number of makes an attempt to get proper. Common efficiency opinions permit ineffective practices to be terminated earlier than they sap sources.
  • Sharing – DevOps encourages collaboration between groups and disciplines. Engineers and operators ought to share insights from their actions, together with successes resembling new automation instruments and failures like shifting too quick and breaking an surroundings. Proactive sharing lessens the dangers of group assume, siloed info, and perpetuated inefficiencies.

These 5 rules foster sturdy DevOps practices inside your group. They information you in the direction of embracing the DevOps methodology by singling out particular attributes which can be attribute of fine implementations.

CALMS offers a helpful mnemonic of areas to focus on for DevOps enhancements. In case your course of isn’t fairly proper, “maintain calm” and begin automating, iterating, and measuring.

CALMing Your Processes

To CALM your processes, first tackle any blockers that stop individuals from embracing the DevOps tradition. Subsequent determine alternatives to improve inefficient workflows by eradicating them altogether, breaking steps into lean iterations, or incorporating automated instruments that carry out repetitive duties for you.

After you’ve utilized your enhancements, measure their results to grasp whether or not they’re working. Use the insights out of your information to make additional changes that focus on particular issues. Proceed iterating in adjust-measure-improve cycles till your information confirms the meant impact has materialized.

Share what you’ve discovered with these round you as your course of develops. This may very well be throughout a retrospective nevertheless it’s typically extra helpful to disseminate info because it’s amassed. This retains everybody knowledgeable of what’s occurring, the place you’re headed, and the the reason why explicit approaches are being favored.

What Ought to You Measure?

Making the appropriate measurements is a crucial a part of DevOps success. With out information you don’t understand how properly you’re performing. You might need a way that you simply’re succeeding or falling behind however this may very well be exaggerated or an entire reversal of what’s truly occurring.

The 4 DORA metrics are a superb place to begin for DevOps efficiency measurement. These observe Deployment Frequency, Change Lead Time, Change Failure Price, and the Time to Restore Service after an incident. Combining DORA evaluation with the CALMS framework provides you tangible information and a framework for enhancing your outcomes.

You would possibly discover your deployment frequency trending downwards over time, for instance. It is a dangerous signal – it’s taking longer for code to achieve clients, however you may not know why. The CALMS framework offers strategies for resolving the issue. It may very well be that there’s too many steps to launch new modifications, one thing that’s resolvable by means of automation. Alternatively, revisions could be getting blocked as they transfer between groups, indicating a loosening of lean rules and a degrading DevOps tradition. This would possibly demand extra cross-discipline dialogue to repair.

How CALMS Permits DevOps Success

CALMS isn’t one other empty buzzword. It helps solidify and consolidate DevOps finest practices, making the sometimes imprecise idea extra approachable. There’s multiple technique to do DevOps however the most effective implementations might be constructed on the 5 CALMS rules.

You should use CALMS to identify each issues and alternatives. There could be rules that you simply’re lacking or ones that are being underutilized. It’s frequent for organizations to automate components of processes however lack a cohesive DevOps tradition, for instance. Different corporations would possibly enthusiastically advocate the DevOps mindset however lack the information factors to measure their success. Referring to CALMS reveals the lacking pillar in every case.

CALMS showcases how good DevOps hybridizes environment friendly engineering with the mindset and group tradition that helps it. You want to implement sensible steps – principally automation and evaluation – whereas adopting a piece ethic that favors iterative collaboration. Frequently appraising the extent of every CALM precept, then making small modifications to enhance, will steadily progress your DevOps maturity and allow you to attain the overarching goal of transport high quality code extra shortly.


DevOps is greater than instruments and expertise. The CALMS mannequin acknowledges this by additionally emphasizing collaboration and tradition. These may be seen as DevOps’ human aspect. Evaluating your group’s adoption of the CALMS rules signifies whether or not tradition and expertise are optimally balanced to supply DevOps success.

Whereas CALMS is a helpful framework for detecting your strengths and weaknesses, it doesn’t assure you’ll develop into a DevOps high-performer. DevOps is inherently subjective and customizable: the CALMS rules are relevant to most groups, however you possibly can tweak them to align together with your surroundings. Adhering to the framework shouldn’t overtake your sense of the best DevOps implementation to your state of affairs.

Some massive organizations would possibly discover it impractical to rollout one set of DevOps practices throughout all their cohorts, for instance. Small inter-team workflow variances aren’t essentially an issue, particularly when supported by sharing mechanisms – the “s” in CALMS – that permit groups to study from one another and steadily unify their strategies.
