Why each option

The most critical factor for successful Enterprise Architecture (EA) implementation is effectively managing the inherent organizational and cultural challenges associated with change.

ADeveloping data modeling tools

Developing data modeling tools is a technical task within EA implementation, not the most critical success factor for the entire program.

BManaging the challenge of changeCorrect

Enterprise architecture implementation often requires significant changes to an organization's processes, technologies, and even culture. Overcoming resistance to change, fostering stakeholder buy-in, and managing expectations are crucial for the adoption and effective utilization of EA, making change management the most important factor for its success.

CReducing the cost of IT investments

Reducing IT investment costs is a potential benefit of EA, but not the most important factor for its successful implementation itself.

DEstablishing key performance indicators (KPIs)

Establishing KPIs is important for measuring EA's effectiveness, but it comes after the foundational challenge of managing change during implementation.
