Which group provides domain knowledge to ensure data and modeling tasks align with real-world requirements?

• A. Subject matter experts
• B. Data scientists
• C. Project managers
• D. Product owners

Answer: (A)

Subject matter experts provide the domain knowledge needed to ensure data work reflects real-world requirements. They deeply understand the actual processes, terminology, constraints, and stakeholder needs of a given field, so they can define relevant data, labeling schemes, and what success looks like in practical terms. This context helps guide feature selection, data quality checks, and interpretation of model results so the analytics deliver actionable, real-world value. Data scientists contribute the technical methods and modeling skills, while product owners and project managers shape requirements and delivery, but the precise domain knowledge comes from those who work directly in the domain.
