Which of the following represents the GREATEST challenge to implementing IT governance?

While selecting best practices is important, frameworks like COBIT or ITIL provide clear guidance, making this less challenging than human behavior.

Project planning for IT governance can be complex, but standard project management methodologies can address this, making it less challenging than managing human behavior.

Developing a business case justifies the investment but is a finite task, and typically less complex than embedding new behaviors and processes across an enterprise.

Applying behavioral change management is often the greatest challenge because IT governance involves changes to roles, responsibilities, processes, and decision-making authority, which requires significant buy-in and adaptation from individuals across the organization. Resistance to change and difficulty in shifting established habits can impede successful implementation more than technical or planning aspects.
