Who is ultimately accountable for the timely delivery of the product as committed?

The correct understanding highlights that the entire team is collectively accountable for the timely delivery of the product. In Agile methodologies, especially in frameworks like Scrum, the responsibility for delivering a product is not solely on individual roles, but rather on the collaborative efforts of the entire team. Each member contributes their skills and expertise, and together they work toward the commitments made during planning sessions.

While the roles such as the product owner and team lead play significant parts in guiding the team and defining what needs to be done, accountability for delivery ultimately rests with the whole team. This fosters an environment of shared responsibility, ensuring that everyone is engaged and committed to meeting the project goals.

It's important to recognize that the other roles mentioned also have their specific responsibilities. The product owner is key in defining the product vision and prioritizing work, while the team lead facilitates the process and helps manage the team dynamics. However, the active involvement and contribution of all team members are critical to delivering the product in a timely manner. Therefore, the answer emphasizes the collective nature of accountability within the team framework.
