system theory
One of the biggest breakthroughs in how we understand and guide change in organizations is systems theory and systems thinking. There are two main definitions of a system, an implicit and an explicit phrase, with the explicit phrase being used in system thinking by organizations. The definition refers to a system as being a collection of highly integrated parts or subsystems that attain a specific goal, through inputs that are processed into precise outputs. And thus if a part of this highly-linked system is changed, the overall system is also changed. This is what 's meant by a system being systemic, i.e. relating and affecting the system as a whole. System & complexity:
Systems range from simple to complex. There are numerous types of systems. For example, there are biological systems (for example, the heart), mechanical systems (for example, a thermostat), human/mechanical systems (for example, riding a bicycle), ecological systems and social systems (for example, groups, supply and demand). Complex systems, such as social systems, are comprised of numerous subsystems, as well. These subsystems are arranged in hierarchies, and integrated to accomplish the overall goal of the overall system. Each subsystem has its own boundaries of sorts, and includes various inputs, processes, outputs and outcomes geared to accomplish an overall goal for the subsystem. Complex systems usually interact with their environments and are, thus, open systems.
A high-functioning system continually exchanges feedback among its various parts to ensure that they remain closely aligned and focused on achieving the goal of the system. If any of the parts or activities in the system seems misaligned, the system makes necessary adjustments to more effectively achieve its goals.
A large class of real world problems can be easily comprehended by taking a physical view of systems associated with them. These systems could be real physical systems such as electrical, mechanical,
