In Scrum, a Cross-Functional team is a group of individuals with diverse skills and expertise who work together to deliver a product Increment. This team structure is designed to maximise collaboration and efficiency by including all the necessary skills to complete the work without relying on external help.
The diversity within a Cross-Functional team means that all aspects of the Project can be addressed internally, leading to a more streamlined and cohesive Workflow. By having all required skills within one team, Scrum reduces the need for external dependencies, which can often cause delays and miscommunication.
