Are cross-functional teams in Scrum optimized to work on a single technical layer only?

In Scrum, cross-functional teams are designed to possess a diverse skill set that allows them to handle various aspects of a project. This means that each team member contributes to multiple facets of the project rather than being restricted to a single technical layer. By being cross-functional, teams can collaboratively address all aspects of product development, including design, testing, coding, and even deployment.

The effectiveness of a cross-functional team lies in its ability to adapt and respond to the needs of the project as a whole. This approach enhances communication, fosters a shared understanding of the product, and accelerates the delivery process. Teams that are not confined to a specific layer can quickly pivot and find solutions that benefit the project more holistically, rather than just optimizing for one technical area.

Therefore, the statement that suggests cross-functional teams are optimized to work on a single technical layer only does not align with the core principles of Scrum. Such a limitation would undermine the team's ability to deliver a well-rounded product.
