March 2025 performance highlights focused on delivering DMN evaluation UX improvements and clarifying documentation across repos. In apache/incubator-kie-tools, the DMN Runner now integrates evaluation data with KIE Sandbox, backed by new state properties and methods to manage/display evaluation results. Evaluation statuses and data structures were refactored to align with the DMN editor, and terminology was standardized by renaming 'Execution' to 'Evaluation' across the runner and related UI for a unified user experience. In IBM/bamoe-docs, the Evaluation Highlights documentation was published, explaining how to enable/disable the feature, the meaning of evaluation badges for decision nodes, and the expression hit count for Decision Tables and Conditional Expressions in both form and table modes.
