Engineering managers & team leads sit "in between" Aha! Roadmaps and Aha! Develop. They more than just team owner permissions, but not full workspace contributor permissions.
Key use cases
Team leads can provide initial estimates on features before they're ready to be assigned over to the team for delivery.
Team leads can manage existing releases to set capacity for their teams and keep release plans up-to-date.
Team leads can create new releases to reflect work the team is doing.
