Healthcare systems are complex in that they are diverse in both structure (e.g. nursing units, pharmacies, emergency departments, operating rooms) and professional mix (e.g. nurses, physicians, pharmacists, administrators, therapists) and made up of multiple interconnected elements with adaptive tendencies in that they have the capacity to change and learn from experience.
Complexity theory emphasizes interactions and the accompanying feedback loops that constantly change systems. While it proposes that systems are unpredictable, they are also constrained by order-generating rules. [6]: 74 Complexity theory has been used in the fields of strategic management and organizational studies.
Examples of hard complexity theories include complex adaptive systems (CAS) and viability theory, and a class of softer theory is Viable System Theory. Many of the propositional consideration made in hard theory are also of relevance to softer theory. From here on, interest will now center on CAS.
It has also been used in health-care research, including to examine the complexity of care in the British National Health Service, [35] the nature of knowledge in health care, [36] and the fight against HIV/AIDS in South Africa. [37] In 2017 the RAND Corporation used the Cynefin framework in a discussion of theories and models of decision ...
A complex system is a system composed of many components which may interact with each other. [1] Examples of complex systems are Earth's global climate, organisms, the human brain, infrastructure such as power grid, transportation or communication systems, complex software and electronic systems, social and economic organizations (like cities), an ecosystem, a living cell, and, ultimately, for ...
Methodologically, social complexity is theory-neutral, meaning that it accommodates both local and global approaches to sociological research. [2] The very idea of social complexity arises out of the historical-comparative methods of early sociologists; obviously, this method is important in developing, defining, and refining the theoretical ...
Computational complexity theory, a field in theoretical computer science and mathematics; Complex systems theory, the study of the complexity in context of complex systems; Assembly theory, a way of characterizing extraterrestrial molecular complexity to assess the probability of the presence of life
Ralph Douglas Stacey (October 1948 – September 4 2021) was a British organizational theorist and Professor of Management at Hertfordshire Business School, University of Hertfordshire, in the UK and one of the pioneers of enquiring into the implications of the natural sciences of complexity for understanding human organisations and their management.
