Fig. 2. Statistical process control chart showing the nonoperative performance of Operating Room of the Future (ORF) surgical teams working in standard operating rooms during the 6 months leading up to ORF inauguration and then continuing for the first 6 months of ORF utilization. Each data point is the average for a bin of five consecutive nonoperative times for which a surgeon followed themselves. The Center Line denotes the average nonoperative time for the 6 months before ORF inauguration. The 1-Sigma, 2-Sigma , and Control Limit lines for the baseline performance are drawn 1, 2, and 3 SDs, respectively, above and below the Center Line.
