Welcome to this site, owned by a person who has an understanding of human behavior and performance in purposeful interacting sociotechnical systems, and applies that understanding in design of interactions in the context of the real systems, to enhance operational resilience and improve safety, quality, and reliability. Some people call this human factors or ergonomics, many refer to it as human performance, and others use the term human & organizational performance. While the label is not that important, it can be confusing to a layperson who wants to develop an understanding.
