Built-in Quality

Posted by Willy-Peter Schaub on Fri 30 September 2022

Ensuring that our solutions meet quality guardrails and governance from ideation to deprecation.

Post-deployment analysis, audits and inspection does not improve quality - it is usually too late, resulting in spectacular failures. While we can learn from these failures, they tend to be expensive and reputation busters - remember, first impressions last!


Quality must be built-in from the moment a team has an idea until the feature or product is deprecated. Also, it is the responsibility of all stakeholders, such as development, operations, architecture, security, and business. It should therefore come as no surprise that built-in quality is the North Star of our EDO Common Engineering Center of Enablement.

Let me explore three (3) of many parts of the built-in quality puzzle in our common engineering system.

Pull Request

I covered many of the myths of pull requests in why we use pull requests with our trunk-based branching strategies and like Mike Kaufman's definition "the pull request integration helps you to keep your main branch clean and detect issues before merging and making the code analysis part of the review process", in his Accelerate DevOps with GitHub book. Used correctly, Pull Requests validate branch policies automatically, trigger validation builds automatically, and even merge to master automatically if all guardrails are met. Any change to the feature branch associated with the Pull Request automatically re-triggers the validations, ensuring that the engineering teams have a near real-time health check of their code and a potential merge with tha master branch.

The Azure DevOps Pull Requests are one piece of our arsenal to be pro- not re-active and help us raise the quality bar through automated validations and a pair of human eyeballs, if and only if required. When we change our Azure Pipeline blueprints, for example, stakeholders from common engineering, operations, security, and/or site reliability engineering are looped in if the change impacts their area of responsibility.

TIP - Pull Requests are autonomous stewards of our Guardrails and complement our peer-programming, by creating awareness of our engineering efforts across differing engineering disciplines. Fosters resilience!

Application-type CI/CD Blueprints

One of our great innovations, the Azure Pipeline blueprints, deliver consistency, standardization, foster collaboration, all of which contribute to the built-in quality. A neat side effect is that they also enable self-service automation, removing mind-numbing and error prone processes - it is a win:win.


With the blueprints, made up of a collection of re-usable templates, most of our big rocks of continuous innovation, enablement, and built-in quality are ticked off in our continuous integration (CI) and delivery (CD) pipelines.

TIP - Watch this space. We will open source our blueprints on GitHub soon!



In the armed forces pathfinders are specialized troops inserted to perform a reconnaissance to gather information, setup and operate drop zones. They share their specialized skills and gather intelligence.


In our world, we insert our engineers to software delivery teams to share their expertise, steward Guardrails, gather information on challenges and how we can improve our common engineering ecosystem to empower all engineers.

By understanding our stakeholders and sharing our learnings with the engineers, we ensure that we continuously improve the built-in quality of both our common engineering system and our products. It is another win:win!

HINT, HINT ... I hope that our Quality Assurance engineers will create a follow-on post to explore how we build-in and validate quality through our quality assurance services.
