hardBusiness Analyst interview question

A senior stakeholder is convinced of the cause of a problem, but your data analysis points to a different cause. How do you handle it?

What the interviewer wants to hear

  • Check your own analysis and data quality first
  • Meet privately before any wider presentation
  • Present the evidence clearly and respectfully
  • Acknowledge their experience and explore what the data may miss
  • Propose a way to test both explanations
  • Focus on the shared goal

Model answer

First I would double-check my analysis: data quality, definitions and whether I have looked at the right time period and segments. I would also ask a colleague to review it. Then I would meet the stakeholder privately rather than surprise them in a group meeting. I would start from the shared goal, for example reducing customer churn, and walk through the evidence simply, with a few clear charts. I would acknowledge their experience, because they may know something the data does not capture, and ask what would explain the difference. If we still disagree, I would suggest a way to test both ideas, such as a small pilot or an extra data cut, so the decision rests on evidence rather than opinion. This approach keeps the relationship strong and usually leads to a better answer than either of us had alone.
