A Maturity Model for Continuous Delivery

To maintain a consistent release train, the team must automate test suites that verify software quality and use parallel deployment environments for software versions. Automation brings the CI/CD approach to unit tests, typically during the development stage and integration stage when all modules are brought https://www.globalcloudteam.com/ together. A maturity model describes milestones on the path of improvement for a particular type of process. In the IT world, the best known of these is the capability maturity model , a five-level evolutionary path of increasingly organized and systematically more mature software development processes.

Releases are still a major event, so the team typically bundles groups of unrelated features into big projects. Using automation to eliminate repetitive, error-prone, and time-consuming manual tasks. Operations staff members must manually intervene when things go wrong in production. Teams rely on automation to reduce the risk and stress of releases, but many staff members follow the “automation for automation’s sake” mantra. Changes to the product are becoming less surprising to all involved teams. Release cycles focus on milestones and not on user feedback or market changes.

DevOps Maturity Model

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. In the most ideal situation you want to automatically up- and down-scale the continuous integration services based on how much you are using them. As you make more rapid, smaller software releases through agile development, your focus will become tighter on the individual stages of software development.

Development and operations work in the same technical environment, so developers always consider Ops-related aspects of releases . Teams integrate security scans throughout the DevOps pipeline, making a conscious effort to shift tests left of deployment. Security team members join meetings well before deployments and partake in design and architecture conversations. An outline of who’s responsible for what in a DevOps team (ownership of processes, go-to staff members for disaster recovery, QA tasks, designing CI/CD pipelines, responding to threats, ensuring high availability, etc.). Automated deployment to a test environment, for example, a deployment that is triggered by pushing code to the development branch. Verifying that models meet the predictive performance targets before they are deployed.

As an example the implementation of a new feature must also include a way to verify the expected business result by making sure the relevant metrics can be pulled or pushed from the application. 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.. Advanced practices include fully automatic acceptance tests and maybe also generating structured acceptance criteria directly from requirements with e.g. specification by example and domains specific languages. If you correlate test coverage with change traceability you can start practicing risk based testing for better value of manual exploratory testing. At the advanced level some organizations might also start looking at automating performance tests and security scans.

Self-Testing Code is the name I used in Refactoring to refer to the practice of writing comprehensive automated tests in conjunction with the functional software. When done well this allows you to invoke a single command that executes the tests – and you are confident that these tests will illuminate any bugs hiding in your code. Like any profession, software development has it’s share of oft-forgotten activities that ci cd maturity model are usually ignored but have a habit of biting back at just the wrong moment. Investing time and money into moving up the DevOps maturity model is also highly beneficial. Each subsequent stage leads to faster time-to-market, improved reliability, reduced IT costs, and better-performing teams.

Laying the foundations for these elements early on makes it much easier to keep progressing as you solve the technical challenges. The practices described at each level of maturity all help you work towards a fast, reliable, repeatable release process that provides rapid feedback on changes. It can help organizations identify initial actions that provide the most significant effect, while indicating which practices are essential, and which should be considered advanced or expert. Agile practices during software delivery enable teams to focus more on business and user value during project planning. Our CEO recently wrote about cloud maturity models that guide companies through the five stages of adopting cloud computing. While the benefits of adopting DevOps are obvious (faster time-to-market, fewer bugs in production, improved code quality, etc.), the transition from traditional software development is rarely smooth and free of setbacks.

One small but impactful way to initiate culture change is to run workshops that identify areas of improvement between your dev & ops teams.

The higher the maturity, the higher will be the chances that incidents or errors will lead to improvements either in the quality or in the use of the resources of the discipline as implemented by the organization. Data generated in the pipeline is likely to include instrumentation, metrics and logging information, as well as build artifacts and report data. Once the waste has been removed and only what is required has been kept and ordered, the next phase inspects the delivery pipeline to ensure that it’s operation is as clean as possible. The second step requires items in the delivery pipeline to be set in order. This requires the pipeline to be arranged so that maximum efficiency is achieved for delivery. The purpose is to identify what is not needed in the delivery pipeline and remove it.

This five-phase continuous delivery maturity model borrows its structure from the CMM, progressing from a base level of no effective capability through beginner, intermediate, advanced and expert stages. It’s a path to the advanced capabilities befitting the DevOps major leaguers that deploy multiple times a day or even multiple times an hour. It might seem strange to state that verifying expected business result is an expert practice but this is actually something that is very rarely done as a natural part of the development and release process today. Verifying expected business value of changes becomes more natural when the organization, culture and tooling has reached a certain maturity level and feedback of relevant business metrics is fast and accessible.

• The company does not need to pass these levels sequentially and can use them as a base for evaluation and planning instead.
• The level of automation of these steps defines the maturity of the ML process, which reflects the velocity of training new models given new data or training new models given new implementations.
• The list is quite intimidating so we’ve highlighted the practices we think you should focus on when starting on this journey.
• 1The process, according to Deming, should then be repeated so that further improvements can be planned and implemented; having the advantage the data and experience from previous cycles is available.

In looking at thethree ways of DevOps- flow, amplify feedback, and continuous learning and experimentation – each phase flows into the other to break down silos and inform key stakeholders. Employees in high-performing DevOps teams were2.2x more likely to recommend their organizationas a great place to work. Dev and ops teams share some responsibilities but still use separate tools. Dev and ops teams use a common set of tools but don’t have visibility into each others’ work. One of the best known open source tools for CI/CD is the automation server Jenkins.

Maturing the Continuous Delivery Pipeline

The key to moving to the next stage is to improve current processes and shift away from measuring internal benchmarks in favor of end-user experience. Deployments never take the operations team by surprise as they work on configuration changes while engineers develop the feature. Teams focus on frequent deployments with small, incremental changes.
