In recent years researchers have used various phrases to distinguish types of systems, including "complex systems," "adaptive systems," and "sociotechnical systems." This essay explores the question of whether such modifiers add specific and useful meaning to the concept of a system. The authors point to the philosophical and logical difficulties of defining these concepts. They resolve the matter by proposing that the notion of a "macrocognitive work system" is the subject matter for human-centered computing.
