Communicating which of the following to staff BEST demonstrates senior management's commitment to IT governance?

While legal and regulatory requirements are drivers for governance, simply communicating them doesn't necessarily demonstrate active management commitment to the governance framework itself.

Approved IT investment opportunities are a result of governance decisions, not the best way to communicate commitment to the governance process itself.

Clearly articulating IT governance objectives and assigning specific responsibilities for achieving them shows that management has thought through how governance will operate and expects active participation from staff. This direct communication provides actionable guidance and accountability, reinforcing the importance of governance.

The need for enterprise architecture is a specific strategic initiative, not the most comprehensive way to demonstrate overall commitment to IT governance across the organization.
