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. With this model we aim to be broader, to extend the concept beyond automation and spotlight all the key aspects you need to consider for a successful Continuous Delivery implementation across the entire organization. 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.
The pointers to the artifacts produced by each step of the pipeline, such as the location of prepared data, validation anomalies, computed statistics, and extracted vocabulary from the categorical features. Tracking these intermediate outputs helps you resume the pipeline from the most recent step if the pipeline stopped due to a failed step, without having to re-execute the steps that have already completed. For online prediction, the prediction service can fetch in a batch of the feature values related to the requested entity, such as customer demographic features, product features, and current session aggregation features.
A Continuous Delivery Maturity Model
It arranges the capabilities into groups and maps the relationships they have to outcomes. When you use a capability model, you accept that high-performance today won’t be sufficient in the future. Business, technology, and competition are always on the move and you need a mindset that can keep pace. In this post, I explain why a maturity model isn’t appropriate and what you should use instead.
Your maturity model creates a spectrum upon which organizations can place themselves, as well as set a target for the future. Andreas Rehn is an Enterprise Architect and a strong advocate for Continuous Delivery, DevOps, Agile and Lean methods in systems development. The levels are not strict and mandatory stages that needs to be passed in sequence, but rather should serve as a base for evaluation and planning. Testing prediction service performance, which involves load testing the service to capture metrics such asqueries per seconds and model latency. For continuous training, the automated ML training pipeline can fetch a batch of the up-to-date feature values of the dataset that are used for the training task.

Continuous improvement mechanisms are in place and e.g. a dedicated tools team is set up to serve other teams by improving tools and automation. At this level, releases of functionality can be disconnected from the actual deployment, which gives the projects a somewhat different role. 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 continuous delivery maturity model the actual release to users separately. 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.
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. Resist the tendency to treat a maturity model as prescriptive directions instead of generalized guidelines — as a detailed map instead of a tour guidebook. Also, this continuous delivery maturity model shows a linear progression from regressive to fully automated; activities at multiple levels can and do happen simultaneously.
Structuring Continuous Delivery implementation into these categories that follows a natural maturity progression will give you a solid base for a fast transformation with sustainable results. Another characteristic of advanced continuous delivery maturity is the use of quantitative measures of software performance and quality, along with metrics that track the health and consistency of the CD process. 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. 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.

The continuous delivery branching model, for example, allows the developers to run tests freely and make changes without destroying the main code line. The developers can develop, test, and modify the code in parallel or isolation and then merge it to a master. Codefresh is the most trusted GitOps platform for cloud-native apps. It’s built on Argo for declarative continuous delivery, making modern software delivery possible at enterprise scale.
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. The goal of level 1 is to perform continuous training of the model by automating the ML pipeline; this lets you achieve continuous delivery of model prediction service. To automate the process of using new data to retrain models in production, you need to introduce automated data and model validation steps to the pipeline, as well as pipeline triggers and metadata management. At this level the work with modularization will evolve into identifying and breaking out modules into components that are self-contained and separately deployed. At this stage it will also be natural to start migrating scattered and ad-hoc managed application and runtime configuration into version control and treat it as part of the application just like any other code.

Testing illustrates the inherent overlap between continuous integration and continuous delivery; consistency demands that software passes acceptance tests before it is promoted to production. Test automation tools include pipeline software like Jenkins; test automation systems like Selenium or Cypress; and cloud services, including AWS CodePipeline or Microsoft Azure DevTest Labs. The continuous delivery maturity model has five steps – base, beginner, intermediate, advanced, and expert. There are also five categories–Culture and Organization, Design and Architecture, Build and Deploy, Test and Verification, Information and Reporting.

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. 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.. Testing is without doubt very important for any software development operation and is an absolutely crucial part of a successful implementation of Continuous Delivery.
The principles and methods of Continuous Delivery are rapidly gaining recognition as a successful strategy for true business agility. ” How do you start with Continuous Delivery, and how do you transform your organization to ensure sustainable results. This Maturity Model aims to give structure and understanding to some of the key aspects you need to consider when adopting Continuous Delivery in your organization.
