I need help on how I can determine what a user gets and why. so I can give my end users an explanation on to why I made a certain decision on how to move forward with a request to creating an MS Team from SharePoint. (ultimately, I’d like something that is almost a script, that helps me determine what a user gets and why.)

For example, If a an end user says, I want the capability to do “xy and z”, I can refer to a document, that starts me off in the right direction.

What is the threshold to create a new team? (What would help me determine to create a new team vs. trying to make an existing team do more things?)(Do I focus more on the team, or the security?) Thanks so much!
