At the advanced level, the team will have the competence and confidence it needs to be responsible for changes all the way to production. 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 the actual release to users separately. The journey that started with the Agile movement a decade ago is finally getting a strong foothold in the industry.

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. CMMI adds Agile principles to CMM to help improve development processes, software configuration management and software quality management.

Instrument application code

There are many paths to take into this realm, we can approach from a tool perspective — how to choose the tool that is right for you. There are many open source and commercial tool offerings, each claiming to simplify the development team’s work while increasing confidence in the published artifacts. Project Managers need to weigh in the needs of the company against the various feature sets of these tools.

At beginner level, the monolithic structure of the system is addressed by splitting the system into modules. Modules give a better structure for development, build and deployment but are typically not individually releasable like components. Doing this will also naturally drive an API managed approach to describe internal dependencies and also influence applying a structured approach to manage 3rd party libraries. At this level the importance of applying version control to database changes will also reveal itself.

The figure below—Continuous Test Engineering Blueprint shows how mature continuous test automation enables, as many relevant tests as possible to be executed as early as possible in the pipeline. For example, the XP requirements management approach, which relies on oral communication, was evaluated as not compliant with CMMI. However it is the logical conclusion of Continuous Delivery where the release to production is completely automated. 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.

The Capability Maturity Model was originally developed as a tool for objectively assessing the ability of government contractors’ processes to implement a contracted software project. The model is based on the process maturity framework first described in IEEE Software[2] and, later, in the 1989 book Managing the Software Process by Watts Humphrey. It was later published in a report in 1993[3] and as a book by the same authors in 1995. It can also be difficult to figure out how the team is progressing on this journey. Not directly it’s original intention, but I intend to use your model as a grading tool in a semester on DevOps at a University of Applied science in the Netherlands.

Like the SW-CMM, EIA/IS 731, IPD-CMM, SA-CMM, and other process improvement models, CMMI models are tools that help organizations improve their processes. This CMMI model is designed to help organizations improve their product and service development, acquisition, and maintenance processes. Concepts covered by this model include systems engineering, software engineering, integrated product and process development, and supplier sourcing as well as traditional CMM concepts such as process management and project management. Each CMMI model is designed to be used in concert with other CMMI models, making it easier for organizations to pursue enterprise-wide process improvement at their own pace.

CMMI was developed by the CMMI project, which aimed to improve the usability of maturity models by integrating many different models into one framework. The project consisted of members of industry, government and the Carnegie Mellon Software Engineering Institute (SEI). The main sponsors included the Office of the Secretary of Defense (OSD) and the National Defense Industrial Association.

Continuous Integration

It does this, in part, by incorporating continuous feedback and continuous improvement into the software development process. Under CMMI, organizations are expected to continually optimize processes, record feedback and use that feedback to further improve processes in a cycle of improvement. At this stage, DevOps teams — continuous delivery experts all adopt some form of DevOps structure — have continuous integration maturity model 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.

Fortunately, SharePoint, Teams and OneDrive for Business provide an elegant solution. After creating a shared folder online, just synch to your local computer and then make sure you close and save your PBIX files after adding critical features – and at the end of every business day. In the video, I demonstrate using Teams and SharePoint online to synch PBIX files with your computer’s file storage and synch-up with cloud storage after you make changes. The idea is to keep your model crisp and to the point so that stakeholder don’t invest their time in looking something which they know is already working well or not required. To truly reach the CD zenith software engineers really have to turn all the IT “dials” to the max.

Build Automation

This CMMI model has a continuous representation, which focuses on measuring process improvement using capability levels. Capability levels apply to process-improvement achievement within individual process areas such as configuration management or verification. The first stage of maturity in continuous delivery entails extending software build standards to deployment. The team should define some repeatable, managed processes that get code to production.

Therefore, developers only run a subset of tests before checking in, and a CI system runs the remaining tests. The CI system acts as a safety net by giving the developer feedback about the tests he did not run. First, there will be many changes during one cycle, increasing the chance the build breaks. Second, developers do not integrate their changes in the broken build; rather, they batch them. Finally, when the build is fixed, all developers integrate their batched changes, leading to a high chance of breaking the build again. This decreases the chance the build will break and increases the ability to check in more frequently.

In this example, every component has a CI system executing unit tests, plus static analysis and code coverage metrics. A successful build promotes the component and triggers feature-level CI systems executing higher-level tests. One distributed product group we worked with mixes the two approaches. On a lower level, the CI system is organized around components, and the output of this triggers multiple-feature CI systems running higher-level acceptance tests in parallel. A multi-stage CI system splits the build and executes it in different feedback cycles. At the lowest level, it has a very fast CI build containing unit tests and some functional tests.
