Introduction
To improve Monte Carlo's data observability platform for better real-time detection of data quality issues, we need to analyze the current system, identify pain points, and propose innovative solutions. I'll outline a comprehensive approach to enhance the platform's capabilities, focusing on key stakeholders and their needs.
