Continuous Integration and the Release Maturity Model

maturity models

Organizations typically have a hodgepodge of manual processes. At this stage, when automation is applied to application delivery, it’s often ad hoc and isolated — usually instituted by a single workgroup or developer and focused on a particular problem. Nevertheless, organizations starting down the continuous delivery path have often standardized portions of software development, such as the build system using CMake, Microsoft Visual Studio or Apache Ant and a code repository, like GitHub. features tutorials, news, and how-tos focused on topics relevant to software engineers, web developers, programmers, and product managers of development teams. In addition to covering the most popular programming languages today, we publish reviews and round-ups of developer tools that help devs reduce the time and money spent developing, maintaining, and debugging their applications. This includes coverage of software management systems and project management software – all aimed at helping to shorten the software development lifecycle .

  • As mentioned above in the table, you can be at one of the four stages of devops maturity model.
  • For example, Base, Beginner, Intermediate, Advanced, Expert are used by InfoQ.
  • Health monitoring for applications and environments and proactive handling of problems.
  • Senior developer and architect with experience in operations of large system.

Many commercial tools strive are kitchen sink solutions targeting large scale enterprise development. Often times these solutions create complications and bottlenecks for small projects that do not need to collaborate with 5000 developers and multiple product lines, or multiple versions. On the other hand some companies need greater central control over the build and release process across their enterprise development groups. With Continuous Deployment we imply a software development practice, for which environments are setup and target objects are deployed in an automatic way. In a basic pipeline the build should be automatically deployed to the test environment. At a more advanced level successful deployments are also automated in a acceptance and production environment.

The pinnacle of continuous delivery maturity focuses on continual process improvement and optimization using the metrics and automation tools previously implemented in stages two through four of the model. Optimizations reduce the cycle time for code releases; eliminate software errors and resulting rollbacks; and support more complex, parallel release pipelines for multiple, concurrent software versions, including A/B experimental releases. Resist the tendency to treat a maturity model as prescriptive directions instead of generalized guidelines — as a detailed map instead of a tour guidebook.

Best Practices for Implementing a Continuous Delivery Maturity Model

Depending on your organization, your end goal may be to have changes deployable within a day . Or your goal may be to achieve continuous deployment, with updates being shipped if they pass all stages of the pipeline successfully. You can also use continuous feedback from production to inform hypothesis-driven development .

ProfessionalDevOps is your one-stop destination for all things DevOps. We leverage our expertise in DevOps to help you enhance your skills to achieve beneficial business outcomes through the adoption of DevOps, the new-age digital technology, and its various branches and methodologies. Deploying is the core of how you release your application changes. In this blog post, we will be exposing maturity level checklists for different DevOps areas so you have an idea where you at in terms of Continuous Delivery. Fully automated provisioning and validation of environments. Level-up on emerging software trends and get the assurance you’re adopting the right patterns and practices.

Continuous Delivery is all about seeing the big picture, to consider all aspects that affect the ability to develop and release your software. For any non-trivial business of reasonable size this will unfortunately include quite a lot of steps and activities. The end-to-end process of developing and releasing software is often long and cumbersome, it involves many people, departments and obstacles which can make the effort needed to implement Continuous Delivery seem overwhelming. These are questions that inevitably will come up when you start looking at implementing Continuous Delivery.

Five levels

GitOps has emerged as a key technology in the cloud native computing space over the last few years. Research into delivery velocity has shown that speeding up software delivery is closely correlated with business success. GitOps is an approach for building incredibly robust and repeatable continuous delivery pipelines. The CDMM can be used to identify areas for improvement and guide an organization’s efforts to implement continuous delivery practices. It can also be used to benchmark the organization’s maturity level and track its progress over time.

Decisions are decentralized to the team and component ownership is defined which gives teams the ability to build in quality and to plan for sustainable product and process improvements. Another problem with compiling the releases is for the development team to have to context switch. Once they finish the feature, it still isn’t released, and sometimes during the deployment or testing problems are found, impacting the current work they are doing. And as developers, our memory gets tested once we are trying to remember the purpose of the feature developed a month ago. As software engineers, we love to develop features for making our customer lives easier, but until those features are available to end-users, it adds no value to the business.

Mehrnoosh Sameki discusses continuous delivery maturity modeles to responsible AI and demonstrates how open source and cloud integrated ML help data scientists and developers to understand and improve ML models better. As an organization evolves, each of its maturity models can evolve. For example, some organizations like to look ove each of their maturity models, each year, to ensure that each maturity model is still useful, and also to update each model as desired, based n the organization’s goals and capabilities. A maturity model is a business tool used to assess people/culture, processes/structures, and objects/technology.

Continuous Integration and the Release Maturity Model

This means that every commit to the workspace is automatically released to production, and thus leading to several deployments of your software during a day.Continuous Delivery is a basic pre-requisite for Continuous Deployment. At certain times, you may even push the software to production-like environment to obtain feedback. This allows to get a fast and automated feedback on production-readiness of your software with each commit.

What tools did you have in mind to “[…] provide dynamic self-service useful information and customized dashboards.” The organization and it’s culture are probably the most important aspects to consider when aiming to create a sustainable Continuous Delivery environment that takes advantage of all the resulting effects. If you are interested how you can work or how a system need to be designed and what transformation you need to do to reach the expert level, don’t hesitate to contact me or read my blog and forthcoming pots. According to the DORA program, a Google Cloud DevOps research team, a company can be at one of the fourth stages of DevOps. TDD evangelist with over 12 years of experience in developing scalable software.

Almost all testing is automated, also for non-functional requirements. It is easy to replace technology for the benefit of something better . Building up your pipeline incrementally, with achievable goals along the way, makes the process more manageable and provides opportunities to take stock and learn from what you have done so far. This article tells the story of a minority woman’s journey from DBA to co-founder & CTO, using open source to overcome gender disparity.


As part of deployment, you should also review your provisioning tasks and requirements. Remember that it’s important to provision the application infrastructure for all required environments, keep environment configuration in check and dispose of any intermediate environments in the process. Most companies already have some data gathering in place or have a customer feedback loop to track how their software is perceived by users. Continuous Intelligence is the automation of this software user tracking process, to enable software companies in developing software features that add the most value.

Therefore the deployment process is an essential part of succeeding as a development team. DevOps isn’t a destination, it’s a journey towards a frequent and more reliable release pipeline, automation and stronger collaboration between development, IT and business teams. This maturity model is designed to help you assess where your team is on their DevOps journey. The CMM focuses on code development, but in the era of virtual infrastructure, agile automated processes and rapid delivery cycles, code release testing and delivery are equally important. Once the application health is measured on different levels, it is expected to ensure that everything is working fine.

The deployment process is manual or semi-manual with some parts scripted and rudimentarily documented in some way. A typical organization will have one or more legacy systems of monolithic nature in terms of development, build and release. Many organizations at the base maturity level will have a diversified technology stack but have started to consolidate the choice of technology and platform, this is important to get best value from the effort spent on automation. For example, many organizations create their own maturity models, sometimes based on public maturity models, sometimes making use of internal confidential information, sometimes in consultation with experts and advisors. This repository links to many maturity models that are created by many people and many organizations. Paul is a Principal Solutions Architect at Weaveworks, where he provides pre- and post-sales technical expertise. brings the CI/CD approach to unit tests, typically during the development stage and integration stage when all modules are brought together. Continuous Integration integrates the new/changed code into the current system after each check-in without any manual steps. This can be realized by using a workflow orchestrator such as Jenkins or VSTS where you can configure a pipeline to do that for you. Best practices for Continuous Integration are having a build that can be used for all environments and using a microservice architecture.

delivery and continuous

A project can focus on producing requirements for one or multiple teams and when all or enough of those have been verified and deployed to production the project can plan and organize the actual release to users separately. At this stage, DevOps teams — continuous delivery experts all adopt some form of DevOps structure — have fully automated a code build, integration and delivery pipeline. They’ve also automated the infrastructure deployment, likely on containers and public cloud infrastructure, although VMs are also viable. Hyper-automation enables code to rapidly pass through unit, integration and functional testing, sometimes within an hour; it is how these CD masters can push several releases a day if necessary. NISI has recently released the Continuous Delivery 3.0 maturity model, or CD3M.

The purpose of the maturity model is to highlight these five essential categories, and to give you an understanding of how mature your company is. Your assessment will give you a good base when planning the implementation of Continuous Delivery and help you identify initial actions that will give you the best and quickest effect from your efforts. The model will indicate which practices are essential, which should be considered advanced or expert and what is required to move from one level to the next. A maturity model can describe its levels and items in terms of qualitative metrics and/or quantitative metrics.

It shall be easy to make adjustments to the code and the architecture. It shall be easy to delete code that is not used anymore and, last but not least it should be fun and innovative approach to work with software development and deliver a smile on the customer’s lips every time. Faster deliveries and keep up with the competition has never been more important than now. Before, it was easier to become complacent and just sell on.

That is what often ends up happening to monoliths because multiple teams maintain one codebase. Each of these Continuous Delivery maturity models mentioned define their own maturity levels. For example, Base, Beginner, Intermediate, Advanced, Expert are used by InfoQ. ThoughtWorks uses CMMI-Dev maturity levels but does not segregate them into different areas.

Identify and monitor key performance indicators for better control over software acceptance and rollback criteria in test and in live production. For example, continually monitored application performance KPIs enable an CD system to automatically roll back a release that exhibits problems in production. Parallel software deployment environments don’t require cloud services, but they are much easier to set up when infrastructure is delivered instantly as a service. Cloud services and CD automation simplify the task to create and manage redundant environments for production, beta and developer code. New releases nondisruptively roll into production after a suitable testing cycle with the help of parallel setups. To maintain a consistent release train, the team must automate test suites that verify software quality and use parallel deployment environments for software versions.

  • IT can once again start pushing innovation instead of restraining it by expensive, slow, unpredictable and outdated processes.
  • A company’s DevOps maturity model has a direct relation with its software delivery model that supports their brand differentiating and revenue-generating applications.
  • The definition of done must also be extended from release to sometime later when business has analyzed the effects of the released feature or change..
  • This is why we created the Continuous Delivery Maturity Model, to give structure and understanding to the implementation of Continuous Delivery and its core components.

As a result of this you can also start cross referencing and correlating reports and metrics across different organizational boundaries,. This information lets you broaden the perspective for continuous improvement and more easy verify expected business results from changes. Build and deployment is of course core to Continuous Delivery and this is where a lot of tools and automation come into the pipeline; this is what is most is commonly perceived when Continuous Delivery is discussed. At first glance a typical mature delivery pipeline can be very overwhelming; depending on how mature the current build and deployment process is in the organization, the delivery pipeline can be more or less complex. In this category we will describe a logical maturity progression to give structure and understanding to the different parts and levels it includes.

But it’s not something you implement overnight in a single step. There are six areas you need to focus on and assess on an ongoing basis as your software production process evolves and your Continuous Delivery model matures. The Continuous Delivery Maturity Model is a 5×6 matrix, consisting of six areas of practice and five levels of maturity. Each of the matrix’s 30 elements defines a required discipline an organization needs to follow, to be considered at that level of maturity within that practice. Since databases schema changes are sometimes delicate, make sure to include your DBA team into the peer review process, so that changes are 1) code; 2) can be merged and patched; 3) can be code reviewed.
