Case study research: the view from complexity science.
Anderson RA, Crabtree B, Steele DJ, et al. Case study research: the view from complexity science. Qual Health Res. 2005;15(5):669-85.
The authors advocate using the complexity science perspective in case study research. They propose that complexity theory, which looks at relationship patterns within a complex adaptive system, is better suited for studying and understanding health care systems than traditional theoretical models.
