Concepts and Frameworks

The Five Learning Disciplines

Developed by renowned systems thinker Peter Senge, these five disciplines each enhance the ability of a person or organization to use learning effectively. Leveraged together, they contribute heavily to the success of learning organizations, defined by Senge as, “…organizations where people continually expand their capacity to create the results they truly desire, where new and expansive patterns of thinking are nurtured, where collective aspiration is set free, and where people are continually learning to see the whole together.”

The five learning disciplines are

  1. Personal Mastery
  2. Mental Models
  3. Shared Vision
  4. Team Learning
  5. Systems Thinking

For descriptions of each of these disciplines, visit the Society for Organizational Learning’s website. To read a more in-depth discussion of Senge’s ideas, we recommend this article from Infed.


U Process

U Process, also know as Theory U, is a useful methodology for collectively approaching difficult problems and developing innovative, appropriate solutions. This process, pictured below, guides participants through a series of steps. It begins by observing reality as it is, retreating and reflecting on those observations, and then enacting a new reality.

For more information about U Process, visit the Presencing Institute. This presentation by Dr. C. Otto Scharmer of the Presencing Institute is especially helpful in understanding the theory.

Biomimicry is the concept of using natural forms, materials, and processes as models to drive human innovation. Because it has been evolving and perfecting its systems for millions of years, nature can provide powerful examples of sustainable solutions. For instance, an oyster’s mechanisms for filtering water might be used to inform man-made filtration systems, or a forest ecosystem that breaks down and reuses its own detritus might inform the design of a waste-treatment facility.

The consulting company Biomimicry 3.8 has a great introduction to this approach to problem solving. More helpful resources can be found at the Biomimicry Institute, their nonprofit counterpart. For teaching and learning resources check out AskNature Resources.


Double Loop Learning

Double loop learning is a learning process that goes beyond surface level goals, techniques, and responses to target the  assumptions and values underlying the system. The idea is to enable solutions to problems that are complex and ill-structured. Argyris and Schön, who developed and elaborated the double loop theory, describe different types of learning as follows:

When the error detected and corrected permits the organization to carry on its present policies or achieve its presents objectives, then that error-and-correction process is single-loop learning. Single-loop learning is like a thermostat that learns when it is too hot or too cold and turns the heat on or off. The thermostat can perform this task because it can receive information (the temperature of the room) and take corrective action. Double-loop learning occurs when error is detected and corrected in ways that involve the modification of an organization’s underlying norms, policies and objectives.

If we continue the example of the thermostat above, a double loop thermostat would ask why before altering the temperature–are there people here to enjoy the heat? Are the people dressed appropriately? Could we open or close a window instead? The double loop thermometer takes into account its current environment and situation when making decisions.To learn more about this learning tool, try reading Infed’s article on Chris Argyris or visiting Instructional Design’s Double Loop Learning page.

The Iceberg Model

The iceberg model is a valuable tool to encourage systemic thinking and help you contextualize an issue as part of a whole system. By asking you to connect an event–a single incident or occurrence–to patterns of behavior, systems structures, and mental models, the iceberg allows you to see the structures underlying the event. Just like an iceberg, 90% of which is invisible beneath the water, these structures are often hidden below the surface. However, if you can identify them and connect them to the events that you are seeing, you may be able to develop lasting solutions that target the whole system rather than short term, reactive solutions.

The Bathtub Theorem

This simple theorem is easily visualized by imagining a bathtub: water enters the tub via the faucet and it exits through the drain, through leaks, or by overflowing the sides. These two flows of water–the inflow and the outflow–together determine the water level and stability of the bathtub. To maintain a constant level, the inflow must equal the outflow.

The bathtub theorem is a useful mental model when thinking about issues like economics and climate change. This simulation from Climate Interactive is an excellent way to familiarize yourself with the theorem while simultaneously learning about the relationship between carbon emissions and atmospheric carbon dioxide levels.



Stock and Flow Diagramming

These diagrams are an important way to visualize and understand how a system of different elements is working together. As Donella Meadows wrote in Thinking in Systems,”If you understand the dynamics (behavior over time) of stocks and flows, you understand a good deal about the behavior of complex systems.” In describing stocks and flows, Donella Meadows stated, “A system stock is just what it sounds like: a store, a quantity of material or information that has built up over time.  It may be a population, an inventory, the wood in a tree, the water in a well, the money in a bank…Stocks change over time through the actions of flows, usually actual physical flows into or out of a stock–filling, draining, births, deaths, production, consumption, growth, decay, spending, saving.  Stocks, then, are accumulations, or integrals, of flows.”

Below is a more complex example of a stock and flow diagram that illustrates the volume of living wood in a forest. For more information on stocks and flows and this diagram, read this excerpt from Thinking in Systems.

Open Space

Open Space is a technique for organizing meetings, conferences, symposiums, and community events. Open Space meetings are focused around a particular topic or purpose, but they begin without a formal agenda. Participants are asked to create the agenda themselves by proposing topics that feel important to them, and in this way Open Space events are tailored to the needs and interests of participants. For more information about Open Space principles and hot to use them, read this primer or visit


World Café

World Café is a tool that facilitates dialogue amongst large groups. It’s simple, flexible approach is based on seven design principles:

  1. Set the Context
  2. Create Hospitable Space
  3. Explore Questions that Matter
  4. Encourage Everyone’s Contribution
  5. Connect Diverse Perspectives
  6. Listen Together for Patterns and Insights
  7. Share Collective Discoveries

Events hosted using the World Café process are broken into multiple short discussion sessions. During each session, participants meet around tables in small groups to discuss a question posed at the beginning of that round, and then move to a new table with different people before the next round of discussions. At the end of the meeting, insights from the many discussions are shared with the entire group.

If you’d like to learn more, the World Café website is a great source of information about this dialogue process.


Graphic Facilitation

Graphic facilitation is the process of translating complex concepts into a visual language of words and pictures and recording them in real time. This strategy can be a very effective way to summarize and communicate complex ideas and to allow participants to see and internalize the big picture of a discussion or presentation.

The following example by graphic facilitator Brandy Agerbeck helps to explain the graphic facilitation process and how it can help clarify and synthesize ideas. For more information, the Center for Graphic Facilitation is a great resource, as is Stine Arensbach’s Graphic Facilitation website.
