View the Governance and Management Frameworks for a Governance Instance. Frameworks are only viewable if they were created by your Organization (i.e., your organization will create/setup a governance instance with the applicable framework(s) that will be used, e.g., ITIL - a process framework and COBIT 5 - a governance framework). You can create a new Framework or add Domains or change the descriptions of the framework(s); however, you can not change the initial framework(s) defined.

If a Framework had been created by your Organization you might be able to modify it.
