The document proposes a domain-driven data mining methodology to efficiently process tickets in an IT organization. The methodology involves classifying tickets by category, identifying tickets with high issue rates, applying root cause analysis (RCA) to determine the root cause of issues, and applying continuous improvement (CI) to identify and implement solutions. An experiment applying the methodology to a banking sector showed it improved processing rates and reduced tickets with issues compared to processing tickets independently without categorization or RCA/CI. The methodology aims to efficiently solve ticket issues, increase customer satisfaction and requests, and improve processing without waiting for service level agreements.
