The main role of the team lead in Disciplined Agile is toensure that the team builds the product right. This involves guiding the team to follow the appropriate practices, ensuring high-quality standards, and removing any impediments that could affect the development process. The team lead facilitates the team’s work, helps them adhere to their chosen way of working, and ensures that the product meets the necessary quality standards and fulfills customer requirements. While other roles, such as product owner or architect, might focus more on defining the right product or coordinating efforts, the team lead's primary responsibility is to ensure proper execution and adherence to quality practices.
