Explanation
A sales process is a set of stages that an opportunity goes through as it moves from creation to close. A record type is a way to offer different business processes, picklist values, and page layouts to different users based on their profiles. A page layout controls the layout and organization of detail and edit pages for a specific object and record type combination. To meet the requirement of having different fields and stages for each team, you need to create three sales processes for each market segment, three record types for each sales process, and three page layouts for each record type.
