The document discusses the application of lean six sigma tools in healthcare settings, specifically within the UK's National Health Service (NHS). It notes that while terms like "six sigma" are viewed negatively, tools focused on continuous improvement, reducing waste, and improving processes are accepted. Popular tools used include control charts in Minitab to monitor performance at ward and business levels, as well as cause-and-effect diagrams, process mapping, and A3 reports in Quality Companion. Sensitivities within the NHS require terminology to focus on patients and the future rather than defects. Large continuous improvement programs in the NHS aim to reduce wait times and increase resources for direct patient care.
