Why This Question Matters

This easy-level System Design/Architecture question appears frequently in data engineering interviews at companies like BCG. While less common, it tests deeper understanding that distinguishes strong candidates.

How to Approach This

Start by clearly defining the core concept being asked about. Interviewers want to see that you understand the fundamentals before diving into implementation details. Structure your answer with a definition, then explain the practical application with a concise example.

Situation: Complex platforms have multiple stakeholders, ambiguous scope.

Action: (1) Stakeholder workshops—personas, use cases, success metrics; (2) Data discovery—sources, volume, quality, latency; (3) Gap analysis—current vs. desired; (4) Prioritization—MoSCoW or RICE; (5) PRD—scope, assumptions, acceptance criteria.

BCG Style: Align with business strategy; quantify impact. Iterative refinement—prototype early, validate. Define MVP and iterate.
