The significance of the Agile principle regarding working software is that it is considered the primary measure of progress in an Agile framework. This principle highlights the importance of delivering tangible, functional software as a key indicator of whether a project is on track. Rather than relying solely on extensive documentation or predefined plans, Agile practices prioritize the delivery of working software that meets the needs of users.

The reasoning behind this principle is that working software provides immediate value to stakeholders and allows for early feedback. This feedback is essential for adaptive planning and continuous improvement within Agile methodologies. By focusing on delivering working software frequently, teams can ensure alignment with customer needs and environmental changes, which is a cornerstone of the Agile approach.

In contrast, while aspects like marketing, documentation, and testing are important in software development, they do not take precedence over the delivery of working software as a measure of progress. Agile values emphasize practical outcomes and user satisfaction, making the delivery of software that functions and provides value the most critical measure of success in Agile projects.
