Certified Information Systems Auditor (CISA) — Question 103

An online retailer is receiving customer complaints about receiving different items from what they ordered on the organization's website. The root cause has been traced to poor data quality. Despite efforts to clean erroneous data from the system, multiple data quality issues continue to occur. Which of the following recommendations would be the BEST way to reduce the likelihood of future occurrences?

Answer options

• A. Outsource data cleansing activities to reliable third parties.
• B. Assign responsibility for improving data quality.
• C. Implement business rules to validate employee data entry.
• D. Invest in additional employee training for data entry.

Correct answer: C

Explanation

Implementing business rules to validate employee data entry addresses the root cause of the data quality issues by ensuring accuracy at the point of data entry. While outsourcing or assigning responsibility can help, they do not directly prevent errors from happening. Additional training may improve skills but does not guarantee data validation at the source.
