Explanation
The most likely underlying cause for an enterprise not having success implementing IT governance because key staff are not participating in planning meetings is lack of senior leadership commitment. Senior leadership commitment is essential for ensuring that IT governance is aligned with the enterprise's vision, mission, values, and goals, and that it receives adequate resources, support, and oversight. Without senior leadership commitment, IT governance may face resistance, confusion, or indifference from key stakeholders, resulting in poor implementation outcomes. The cause is based on the COBIT 2019 Implementation Guide4, page 25.
