Read the first 7 Troubleshooting & Problem Resolution flashcards as text

  1. A monthly revenue dashboard suddenly shows a 40% drop, but finance reports no real decline. What should the CDO's team check first?

    Answer: Upstream data pipeline loads and source extract completeness

    Sudden metric drops with no business cause usually come from incomplete or failed upstream loads.

  2. Which technique asks 'why' repeatedly to move from a data quality symptom to its underlying cause?

    Answer: 5 Whys

    The 5 Whys method iteratively questions each answer to uncover the root cause.

  3. Two business units report different customer counts from the same warehouse. What is the most likely root cause?

    Answer: Inconsistent business definitions of 'customer'

    Divergent counts from shared data typically stem from differing definitions, which a business glossary resolves.

  4. A Fishbone (Ishikawa) diagram is most useful for which troubleshooting activity?

    Answer: Categorizing potential causes of a recurring data defect

    Ishikawa diagrams organize possible causes into categories such as people, process, technology, and data.

  5. After fixing a corrupted customer address batch, what step best prevents recurrence?

    Answer: Implement validation rules at the point of data entry or ingestion

    Preventive controls at entry or ingestion stop bad data before it propagates.

  6. A data steward and an IT owner disagree over who must fix a recurring data defect. Which artifact should resolve this?

    Answer: A RACI matrix defining data responsibilities

    A RACI matrix clarifies who is responsible, accountable, consulted, and informed for data issues.

  7. Which metric best indicates how quickly the data team resolves reported data issues?

    Answer: Mean time to resolution (MTTR)

    MTTR measures the average time from issue detection to resolution.
