What practice is emphasized for developers when it comes to the Definition of Done?

The practice emphasized for developers regarding the Definition of Done is integrating non-functional features into every increment. This approach highlights the importance of ensuring that all aspects of the product, including non-functional requirements such as performance, security, and usability, are consistently addressed with each increment of work.

By including these non-functional features in every increment, teams can ensure that the product remains viable and meets user expectations throughout the development process. This practice helps avoid the pitfalls of accumulating technical debt and ensures a more maintainable and robust final product.

Integrating non-functional features early and continuously fosters a better understanding of how these features affect the overall user experience and system performance. It promotes quality and reduces the risk of these features being overlooked until the end of the project, which can lead to rushed implementations and poor outcomes.

This continuous integration aligns with Agile principles, emphasizing incremental progress and the delivery of high-quality software consistently, rather than relegating important aspects to be handled at later stages, which might compromise the end product.
