At the Institute for Healthcare Improvement (IHI) Conference in 2015, Don Berwick asked everyone to recommit to improvement science—control charts, Pareto charts, and histograms of performance. He sounded annoyed with the lack of use of Lean Six Sigma tools and methodologies. I understand his frustration. I was there in 2006 when he asked everyone to "pledge allegiance to science and evidence." Over the years, I've done a stroke tally of the quality tools used in IHI poster presentations. I gave each poster one check-mark for each type of tool used (Figure 7.1).
