Representatives from key business units such as operations, marketing, HR are best described as which role?

• A. Domain experts
• B. Compliance officers
• C. Project sponsors
• D. Technical experts

Answer: (A)

The main idea is that people from operations, marketing, HR bring deep knowledge of how the business actually runs and what it needs to achieve. These representatives are domain experts—they understand the day-to-day workflows, data used, performance metrics, and decision criteria specific to their area. In a governance or program-management context, their insight helps translate business goals into concrete requirements, validate proposed solutions against real-world practices, and ensure every deliverable will work within the existing processes. They also act as the acceptance voice, confirming that outcomes will drive the intended business value.

Other roles don’t fit as neatly. Compliance officers focus on rules, policies, and risk controls; project sponsors are senior leaders who back the initiative with support and funding; technical experts know the technology but aren’t necessarily the right bridge to the business domain. That alignment with actual business operations is what makes domain experts the best fit for representing key business units.
