Who is responsible for resolving defects found mid-iteration?

The Agile Team Member is primarily responsible for resolving defects found mid-iteration because Agile methodologies emphasize collective ownership and collaboration within the team. In this context, each team member, regardless of specific roles, is expected to contribute to problem-solving and addressing issues that arise during the iteration.

This collaborative approach ensures that issues are addressed quickly and efficiently, allowing the team to maintain momentum and adhere to the iteration goals. While the Quality Assurance Team may identify defects and the Product Owner prioritizes overall product features and requirements, it is the Agile Team Members who take direct action to solve these issues in a way that aligns with Agile principles. This fosters an environment of shared responsibility and enhances the team's ability to deliver a high-quality product.
