Every industry is impacted by digital disruption. Customers expect continuous value from companies that implement change rapidly. Although many enterprises strive to provide value on demand, they focus on continuous delivery. In today's flexible world, new and improved items are offered to clients every minute, making their lives convenient and pleasant. When a company receives fresh insights into client needs, it is crucial to quickly translate those insights into a product or service before they become dated or are imitated. With agile, we have already made several process improvements for employees to produce products quickly and to a high standard. However, there are some operational and development procedures that must be completed and cannot be bypassed. In these situations, having a constant value delivery attitude is necessary.
Scaled Agile Framework (SAFe) is an open-source knowledge base incorporating Lean, Agile and DevOps principles and practices organizations can use to deliver high-quality value to customers in the shortest sustainable timeframe possible. CALMR approach to DevOps in SAFe or agile is the best way to achieve this quantitative value in the quickest period possible.

What is the CALMR Approach to DevOps?
DevOps is a mindset in addition to being a culture and collection of technical methods in a way of thinking. For all the individuals required to plan, test, develop, deploy, release, and maintain a solution, DevOps offers communication, integration, automation, and tight cooperation. DevOps is a term that encompasses the relationship between development and operations teams. The goal of DevOps is to improve communication and collaboration between these two groups in order to deliver software faster and more efficiently. There is typically tremendous tension between individuals who design solutions and the person who supports and maintain those solutions in the absence of DevOps. DevOps is used by SAFe organizations to eliminate organizational silos and create Continuous Delivery Pipelines (CDPs), which are high-performance innovation engines that can offer market-leading solutions quickly.
There are a variety of approaches to DevOps, but one of the most popular is the CALMR approach. CALMR stands for culture, automation, lean, measurement, and recovery. The CALMR approach to DevOps is a set of best practices that focus on making the transition to DevOps as smooth and stress-free as possible.
The CALMR approach to DevOps includes these five key elements in order to create a successful and sustainable DevOps adoption. Cultural change is necessary in order to shift the mindset of an organization from one of silos and competition to one of collaboration and shared success. Once the culture is changed, automation can be used to streamline processes and reduce the need for human intervention. Lean practices help to eliminate waste and maximize efficiency. Measurement is essential in order to track progress and identify areas for improvement. And finally, recovery planning ensures that the system can quickly and efficiently recover from any incidents that occur.
Why to Use the CALMR Approach to DevOps?
The DevOps CALMR approach focuses on creating a culture of shared responsibility between development and operations teams, automating repetitive processes, using metrics to measure success, and sharing knowledge and best practices across the organization.
By implementing the CALMR approach to DevOps, organizations can improve their software delivery process and increase efficiency. A CALMR approach to DevOps is a comprehensive approach that covers all of the essential elements of a successful adoption. The best practices to make the transition to DevOps smoother and more successful include:
- Culture refers to the way your organization approaches software development and delivery. It includes creating a collaborative environment where teams can work together efficiently and effectively.
- Automation is key to making the DevOps transition smoother. By automating repetitive tasks, you can free up time for your team to focus on more strategic initiatives.
- Lean principles help you streamline your process and reduce waste. This includes identifying and eliminating unnecessary steps in your process.
- Measurement helps you track your progress and identify areas for improvement. Without measurement, it’s difficult to know whether or not your efforts are paying off.
- Recovery is essential for dealing with incidents and outages. A good recovery plan will help you get back up and running quickly in the event of an issue.
In order to operate effectively, enterprises must incorporate diverse processes, technologies, values, and policies. In order to achieve the desired outcomes, it is imperative to cultivate DevOps in all five areas of CALMR with care and balance. With the CALMR approach to DevOps, resulting in a continuous value stream, a business can achieve -
- Improved product innovation security and quality
- Accelerated learning cycles and reduced deployment risk
- Decreased time to market for the solution
- Enhanced solution caliber
- Shorter time to fix problems
- Fewer errors and flaws
- Shortened production incident Mean Time To Recovery (MTTR)

The CALMR Approach to DevOps Includes
While most DevOps teams concentrate on automation, efficient DevOps calls for much more. Experts in continuous value delivery use the components of the DevOps CALMR approach to guide their decisions and behavior.
Let's take a closer look at the components :
1. Culture
DevOps makes use of the culture crafted by incorporating the framework's Lean-Agile principles, practices, and attitudes. Some operational duties can be transferred upstream using DevOps, while development work is carried through to deployment downstream. In a DevOps CALMR approach production setting, the solution is used and tracked.
The fundamental values of Culture include :
- Customer Centric: Value is based on an organization's capacity to recognize and address consumer needs. Everyone involved in the VS or value stream needs to be totally conscious of the clients they are serving.
- Co – operation: Effective teamwork between production, management, security, and others is essential to DevOps. These teams need to routinely collaborate to make sure that the required solutions are created, maintained, and developed in line with the shifting business requirements.
- Tolerance for Risk: DevOps requires a shared knowledge of the reality that every delivery is a test up until the point at which customers verify it. DevOps cultures value taking calculated risks and pursuing ongoing learning and development.
- Sharing Knowledge: Sharing information between departments, ARTs, along with the enterprise as a whole strengthens the enterprise and allows a shift in talents to the left.
2. Automation
As manual operations are inefficient and less effective, quick value delivery, great productivity, and security are priorities for DevOps. Additionally, the use of manual processes raises the possibility of mistakes, which could delay the completion of the project. The CALMR approach to DevOps includes automation in the form of a Continuous Delivery Pipeline integrated as a ‘tool chain’ to decrease the overall processing times and longer feedback cycles. Additionally, if they are failing to deliver the intended values, customer and stakeholder feedback provides evidence to support a remedy.
As part of a DevOps CALMR approach, a CDP or Continuous Delivery Pipeline consists of the following tools:
- Value Stream Management: Value Stream Management solutions provide current visibility into the effectiveness and quality of the VS (value stream) along the continuous delivery pipeline.
- Version Management: These are the tools that keep track of and manage needed changes to the configuration and source files that specify how applications, infrastructure, and systems behave.
- Building as a Code: All systems are treated as highly customizable, disposable commodities in infrastructure-as-code.
- Automated testing: An important factor in delivery acceleration is test automation. Unit, element, integration, performance, regression, acceptability, and testing usability in all of its forms are covered.
- Identifying vulnerabilities: These sensors cover a large portion of the continuous delivery pipeline that is made expressly to find security flaws in infrastructure, networks, and code.
- Continuous Integration: When a developer commits their code, these tools are often automatically launched to manage the build, development, testing, conformance, and deployment processes.
- Analytics and Observation: These technologies gather utilization and performance information from every layer of a stack solution and offer vital information about pipeline efficiency, quality, and value that has been delivered.
3. Lean Flow
Effective Agile approaches and trains aim towards a continuous flow condition. One way to interpret it is as a drive towards software delivery in smaller batches overall. It restricts WIP and offers real-time software visibility.
This eventually results in a higher release frequency and cheaper costs. It also improves predictability, speeds up feedback, and reduces rework. Lean flow aids in accelerating delivery times while ensuring uninterrupted service.
The key elements aiding CALMR approach to DevOps include:
- Minimize Work-in-Progress (WIP): A program kanban allows WIP to be visible to all stakeholders. The advantage of this situation is that all groups can see the obstacles. The final WIP amount can then be balanced against the capacity and development that are available.
- Decreased Batch Sizes: Smaller batch sizes move through the system more quickly. The learning process is accelerated as a result.
- Manage Line Lengths: The length of the queue is a good indicator of how it is going to take to finish the task. In order to ensure rapid flow, wait lengths must be carefully managed. Delivery times increase with queue length.
4. Measurement
DevOps must constantly assess the delivery pipeline and the outcomes it produces. Businesses must develop telemetry that enables them to locate flow bottlenecks and determine whether the quality they are offering their consumers is what they require. Some KPIs used to measure the progress include lead time, cycle time, quality metrics, deployment frequency, WIP volume, etc.
Some of the key metrics to be taken into consideration are -
- Lead Time: The duration between the beginning of development and delivering a working product.
- Deployment Frequency: Describes how often a new product version or a change is deployed to production.
- Return on investment (ROI): An investment in DevOps results in a return to the company.
- Net Present Value (NPV): Return on investment is used to measure the value of a project.
- Customer ticket volume: Amount of support tickets opened per month by customers.
- Customer satisfaction: The percentage of customers who are satisfied with the solutions.
- Time to restore: After a problem has been identified and a solution has been offered, the average time it takes for service to be restored.
5. Recovery
If processes for recovery are not created without simulating failures, quick delivery is too dangerous. Organizations need to think about how they can quickly correct problems by going back in time or moving them forward.
The continuous delivery pipeline needs to be built for slow-risk releases and quick recovery after operational failure in order to allow sustained and frequent value delivery.
The following are the techniques CALMR DevOps approach used to support faster delivery -
- A "stop-the-line" approach: When a problem threatens the value of a solution, team members with a "stop-the-line" approach hold the current operation to focus on it till it is fixed. The problem is then permanently fixed as a result of the lessons learned.
- Plan and rehearse for wrong deployments: Wrong deployments are not the sole possibility in DevOps. They occasionally come to be expected. Teams should create recovery plans in order to lessen the effects of failures and increase the resilience of solutions. Additionally, they must practice them frequently in real or almost real production scenarios.
- Roll back and repair: As production failures tend to be unavoidable, DevOps teams must learn to quickly "repair forward" and, if required, roll back to a ‘formal’ stable state.
In agile, high-quality programs are consistently merged from multiple sources.SAFe incorporates the values, methods, and culture of DevOps. Although the DevOps revolution calls for additional preparation and effort, it is worthwhile. When it comes to achieving DevOps transformation, it is often stated that the habit of persistence leads to the habit of triumph, and the CALMR approach to DevOps is the directing attitude for it.
