Which principle encourages teams to regularly integrate their work?

The principle that encourages teams to regularly integrate their work is Continuous Integration. This practice is fundamental in Agile and SAFe frameworks as it involves frequently merging code changes into a central repository, followed by automated builds and tests. This integration process helps teams detect errors quickly and improve software quality by ensuring that all pieces of the project are compatible with one another and function as intended. Regularly integrating work prevents the buildup of larger issues that can arise when components are integrated infrequently, making it easier to identify and resolve problems early in the development cycle. This practice fosters collaboration among team members and supports a culture of continuous feedback and improvement, which are essential elements of Agile methodologies.

The other principles, while important to the overall framework, focus on different aspects of Agile development, such as delivering value to customers and enabling team autonomy. However, they do not specifically address the integration of work products in the same way that Continuous Integration does.
