Boom now has seven standard roles: Owner, Admin, Member, Developer, Inbox Operator, Billing Manager and Viewer. Each person has exactly one, and it decides what they can launch, publish, approve, export and send as rewards, in the app, through the API and in the assistant. Buttons a person cannot use are hidden or disabled instead of failing with an error, and each role lands on a page it can use: Inbox Operators open the inbox, Billing Managers open billing.
Owners and Admins can see exactly what every role can do in Settings › Organization › Roles. Expand any row to see the individual actions. Change someone's role in Organization › General › Members.
