Step-by-step explanation:
The role that ensures that the Product Owner and Developers are directly collaborating is (a) Scrum Master. The Scrum Master is critical in facilitating communication and cooperation between the Product Owner and the Development Team. The Scrum Master not only supports the team in understanding the project goals but also ensures team interaction is smooth and effective. This support is crucial for the success of Product Development, which relies on a robust collaboration strategy. In this role, the Scrum Master must possess strong team interaction abilities and technical skills to efficiently navigate through the intricacies of product and application training, stakeholder management, and the overall product development process.
As a stakeholder in the project, the Scrum Master understands the importance of buy-in from all involved parties, which includes the communication of the project plan and eliciting feedback at all stages. Ensuring seamless collaboration is pivotal in turning concept into reality, much like a director collaborates with actors and production teams during the course of rehearsals in a theatrical production. Through their unique position, the Scrum Master promotes sustainability and alignment within the team, thereby playing a key role in the advancement of collaborative projects.
