Stratified Systems Theory is a framework developed by Eugene E. McClain that focuses on understanding complex systems through different levels of organization. It emphasizes that systems can be stratified into various layers, each with its own characteristics and functions. This approach helps in analyzing how different components interact and contribute to the overall behavior of the system. The theory is applicable in various fields, including sociology, biology, and organizational studies. By breaking down systems into stratified levels, researchers can better understand the dynamics at play and identify how changes in one layer can impact others, leading to a more comprehensive understanding of the system as a whole.
