Step-by-step explanation:
The most important concern for multiple Scrum Teams working from the same Product Backlog is c) Clear communication. The alignment of the team members' ideas, which promotes sustainability, is vital for the smooth operation and coordination of the teams. Without clear communication, the teams may face conflicts or overlap in their work, leading to inefficiencies and a waste of resources. Effective communication involves being open, transparent, and developing trust among team members, which facilitates better understanding and collaboration.
Trust and communication are foundational for any collaborative project aimed at being productive. Identifying the right team members and utilizing effective negotiation skills are secondary factors but equally necessary to advance collaborative projects. It helps to manage disputes and conflicts with a team-oriented approach. Being forthcoming in communications and making a concerted effort to align with the team's goals rather than over-delivering is also key to success.
