Which of the following BEST facilitates the adoption of an IT governance program in an enterprise?

Defining clear roles and responsibilities is important for program execution but doesn't primarily facilitate adoption, which is about acceptance and integration.

A comprehensive business case justifies the initiative's existence but does not directly address the human factors required for its internal adoption.

Communicating the strategy is part of addressing change, but 'addressing behavioral and cultural aspects' is a broader and more impactful approach to overcoming resistance and ensuring buy-in.

IT governance introduces new policies, processes, and responsibilities that can significantly impact employees' daily routines and power structures. Addressing the behavioral and cultural aspects, such as resistance to change, lack of understanding, or misalignment with existing values, is crucial for gaining buy-in and ensuring the program's successful integration and sustainability within the organization.
