●Inquiry recommendation
To ensure meaningful interpretation of these trends, all HSCTs should adopt statistical process control (SPC) charts, as developed by Walter Shewhart in 1939. SPC charts use calculated upper and lower control limits to distinguish between normal variation in a stable process and significant long-term shifts in performance. These charts provide a clear visual flag as to when further investigation is warranted, promoting a data-driven approach to service improvement.

How this page is built
Source and Response are verbatim from primary documents. The Evidence trail records published activity since — written statements, consultation outcomes, inspection findings, parliamentary references. The Index does not paraphrase or characterise intent; it tracks what has been published. Where the evidence is the absence of action (a missed deadline, a slipped timetable), that absence is documented from primary sources rather than inferred.
This recommendation's data is verified periodically against primary sources. The Index is monitored for staleness weekly.
