摘要： A web-based data analysis and tracking system and method for a medium to large organization. Metrics can be determined by asking pre-defined and special questions designed and modified by the facility or organization. The totality of answers to these questions represent a set of metrics that can be weighted and analyzed to produce comparisons with standard or chosen thresholds and/or industry standards. Compliance with best practices can be evaluated, and variances from best practices can be flagged and made visible. The present invention first assures that the organization has reliable data. Next, it analyzes this data to form comparisons and usable output. Finally, it presents the output in various graphical formats that can be used to base management decisions upon such as dashboards, graphs and textual output.
