What's a System?

Adapted from the Field Guide to Consulting and Organizational Development: Collaborative and Systems Approach to Performance Change and Learning.

One of the biggest breakthroughs in how we understand and guide change in organizations is systems theory and systems thinking. To understand how they are used in organizations, we first must understand a system. Many of us have an intuitive understanding of the term. However, we need to make the understanding explicit in order to use systems thinking and systems tools in organizations.

Simply put, a system is an organized collection of parts (or subsystems) that are highly integrated to accomplish an overall goal. The system has various inputs, which go through certain processes to produce certain outputs, which together, accomplish the overall desired goal for the system. So a system is usually made up of many smaller systems, or subsystems. For example, an organization is made up of many administrative and management functions, products, services, groups and individuals. If one part of the system is changed, the nature of the overall system is often changed, as well -- by definition then, the system is systemic, meaning relating to, or affecting, the entire system. (This is not to be confused with systematic, which can mean merely that something is methodological. Thus, methodological thinking -- systematic thinking -- does not necessarily mean systems thinking.)

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 (for example, predator/prey) and social systems (for example, groups, supply and demand and also friendship). 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 weakened or misaligned, the system makes necessary adjustments to more effectively achieve its goals.

A pile of sand is not a system. If you remove a sand particle, you have still got a pile of sand. However, a functioning car is a system. Remove the carburetor and you no longer have a working car.

Five Disciplines of Systems Thinking -- Per Peter Senge

Peter Senge wrote a seminal book about systems thinking, The Fifth Discipline (Doubleday, 1990). In his book, he suggested five disciplines necessary to cultivate systems thinking in an effort or organization. In addition to the discipline of systems thinking, he suggests the following four disciplines, as well.

Personal Mastery

Senge describes personal mastery as "continually clarifying and deepening our personal vision, of focusing our energies, of developing patience, and of seeing reality objectively" (The Fifth Discipline, Doubleday, 1990, p. 7).
Overview of Personal Mastery
Personal Wellness
Personal Development

Mental Models

Senge explains "Mental models are deeply ingrained assumptions, generalizations, or even pictures or images that influence how we understand the world and how we take action" (p. 8).
Inquiry and Advocacy are two primary techniques to identify and reframe mental models

Building Shared Vision

Senge notes "If any one idea about leadership has inspired organizations for thousands of years, it's the capacity to hold a shared picture of the future we seek to create" (p. 9).

Team Learning

Senge asks "How can a team of committed managers with individual IQs above 120 have a collective IQ of 63?" (p. 9.).He adds "Team learning is vital because teams, not individuals, are the fundamental learning unit in modern organizations" (p. 10).
