The purpose of this study is to systematize the perspectives for work process diagnosis in healthcare based on a quality management approach. Three general perspectives are established to achieve this, related to process structure, process contents, and process management. These three general perspectives are then developed in detailed considering nine healthcare characteristics represented by such statements as "must respond to significant differences among individual patients", "patient's condition changes on a moment-by-moment basis," and so on. A list of 278 specific perspectives for healthcare work process diagnosis is prepared from this. Finally, the list is tested and applied in two hospitals, where we verify its effectiveness by confirming the results of the work process diagnosis before and after its application.
