1. Grasp the basic information of the problem. "The surface of the problem is not equal to the core of the problem", and mastering the overall situation has become the first feature of an effective management tool.
2. Economic practicability. Using tools requires input costs, and managers must measure the relationship between the generated economic value and input costs.
3. scientific. Science emphasizes three characteristics-objectivity, repeatability and measurability.
4. controllability. As a good quality management tool, if users can't control it, this tool is worthless.
Among many excellent quality management tools, RCA and HFEMA have attracted much attention in the medical field in recent years.
"RCA and FMEA are the best management tools to improve the quality of medical services and solve patient safety problems." -Medical quality and patient safety
Root cause analysis once and for all (RCA)
The main logic of root cause analysis (RCA) is: "Only by finding out the root cause and making countermeasures according to the root cause can the same mistake not be made again".
As a structured and systematic problem solving method, RCA not only focuses on the direct cause of the accident, but also gradually explores the potential causes that may lead to the recurrence of similar accidents through analysis and investigation, and takes effective corrective and preventive measures, thus achieving the goal of thoroughly solving the problem and changing "handling the accident+punishing the responsible person" into "active maintenance and prevention".
