Final answer:
If multiple Scrum Teams are working on the same project, they should use a shared Product Backlog with clear priorities and team responsibilities, ensuring task deadlines are met for project success.
Step-by-step explanation:
When more than one Scrum Team is working on a single project or release, it's important to organize the Product Backlog in a way that maximizes efficiency and minimizes confusion. A shared Product Backlog should reflect the priorities of the project, with clear identifiers for which team is responsible for each item. The backlog should be well-defined so that dependencies and overlaps can be managed across teams.
Task deadlines are especially critical as they contribute to the overall success of the project. For instance, in developing a new video game controller, missing deadlines can hinder the team's ability to capitalize on the holiday season sales or to beat competitors to market.
