Using Amazon Well-Architected Tool with Organizations enables both Amazon Well-Architected Tool and Organizations customers to simplify the process of sharing Amazon Well-Architected Tool resources with other members of their organization.

For more information, see [Sharing your Amazon Well-Architected Tool resources](https://docs.amazonaws.cn/wellarchitected/latest/userguide/sharing.html) in the *Amazon Well-Architected Tool User Guide*.

You can delete or modify this role only if you disable trusted access between Amazon WA Tool and Organizations, or if you remove the member account from the organization.
