Which one of the following is an essential aspect of architecture governance?

Authoring the Architecture Definition Document is a deliverable produced by the ADM, which is then subject to governance, rather than an aspect of governance itself.

Architecture governance primarily functions to guide and control the evolution and implementation of the enterprise architecture. A key responsibility is to ensure that all projects adhere to the defined architectural standards, principles, and guidelines to maintain alignment and consistency across the enterprise.

While architecture governance provides strategic direction, it does not typically control the day-to-day operations of implementation and deployment organizations.

Authoring a Communications Plan is a project management activity within the ADM, not a core function of architecture governance.

Conducting Business Scenarios is a technique used in early ADM phases for requirements gathering and architecture definition, not an essential aspect of ongoing governance.
