In some corner of the world, there’s a debate about whether or not it was Aristotle who first asserted that, “the whole is greater than the sum of its parts.” Regardless of who said it first, it describes the result when DevOps and Quality Assurance (QA) merge.
In modern times, Buckminster Fuller, the 20th century systems visionary, used the idea as a springboard for a theory he called “synergetics” — complex and theoretical. But in practical terms, as it applies to software development, project planners and managers can adapt the simplest aspect of (possibly) Aristotle’s theory to build desirable ‘synergy’ between DevOps and QA, bringing projects and outcomes to a new level.
At the intersection of the two disciplines lies the key to faster delivery and reliable quality standards. Sharing common objectives such as accelerated time-to-market, enhanced collaboration, and improved overall software quality, both DevOps and QA aim to deliver value to end-users through efficient processes and reliable software. When a relationship between the two is established using good practices, the project and processes become greater than the sum of their parts.
