LaunchDarkly introduces custom roles to enhance access controls in the developer space. Modeled after Amazon Web Services' IAM service, these roles allow admins to control permissions at a granular level. Custom roles empower teams like Customer Support, Sales, and Marketing to handle issues independently, reducing dependence on engineering teams. For example, customer support can disable problematic features temporarily, sales can manage feature access based on customer plans, and marketing can run A/B tests without coordinating with engineering releases. Engineering teams benefit from custom roles by avoiding destructive operations that might affect other team members or end-users.
