Data accuracy refers to how correctly information reflects real-world values and is foundational to reliable decision-making, compliance, and operational efficiency. Key factors affecting accuracy include human error, poor data integration standards, lack of governance, and outdated information. Best practices for engineers include establishing validation rules at entry points, conducting regular audits, using automated data quality tools, training staff, and implementing governance frameworks. Common obstacles such as data silos, inconsistent formats, and resistance to change must also be addressed.
