Improvement requires changes to be made. Indeed, one of the questions in the Model for Improvement asks "What change can we make that will result in improvement?" Ideas for change are not automatically generated by these tools, but they help analyze problems in detail, and in doing so, potential solutions may be easier to identify. In the healthcare field, a causeand- effect diagram (fishbone diagram) is a tool that assists in analyzing the root cause of a quality-related problem, such as poor performance or safety incidents. This tool allows the team to focus on the root cause of a given problem instead of the symptoms. When there is more than one root cause, the team may need to address each one with a separate fishbone diagram process.
