How closely have you interacted with testers and developers?

In my practice, I have always maintained close interaction with testers and developers. This allowed for timely identification and resolution of issues, alignment of requirements, and improvement of product quality. For example, I participated in daily stand-ups where we discussed current tasks and potential risks, as well as conducted joint sessions on requirements analysis and test case review. This approach significantly reduced the time needed to fix errors and increased the overall team efficiency.
