Review Questions

• How does effective data quality management impact the performance of cognitive systems?
  • Effective data quality management directly enhances the performance of cognitive systems by ensuring that the input data is accurate and reliable. When high-quality data is fed into these systems, it leads to better predictions, insights, and decision-making outcomes. Poor-quality data can result in flawed algorithms and misleading conclusions, which highlights the importance of maintaining stringent quality controls throughout the data lifecycle.
• Discuss the relationship between data governance and data quality management in organizations.
  • Data governance provides the framework within which data quality management operates. While data governance focuses on establishing policies and guidelines for managing all aspects of an organization's data assets, data quality management ensures that the data meets specific quality standards set by these policies. Together, they create a comprehensive approach to managing information, helping organizations maximize the value of their data while minimizing risks associated with poor quality.
• Evaluate how implementing a robust data quality management strategy can influence business outcomes in an organization.
  • Implementing a robust data quality management strategy can lead to significant improvements in business outcomes by enhancing decision-making capabilities and operational efficiencies. High-quality data enables better customer insights, improved risk assessment, and more effective resource allocation. Organizations that prioritize data quality are more likely to achieve competitive advantages, foster innovation, and adapt quickly to market changes as they rely on accurate information to drive their strategies.
