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. Otto Scharmer of the Presencing Institute is especially helpful in understanding the theory. Biomimicry Biomimicry is the concept of using natural forms, materials, and processes as models to drive human innovation.

That is a central insight of systems theory. Once we see the relationship between structure and behavior, we can begin to understand how systems work. Win games, have fun, make millions of dollars, or all of the above. Information holds systems together and plays a great role in how they operate.

Changing elements has the least effect n the system If interconnections change, the system may be greatly altered. Stocks are the elements of the system that you can see, feel, count, or measure at any given time.

Donella Meadows

Stocks are shown as boxes 2. The flows are arrow-headed pipes, leading into or out of the stocks.

The small T on each flow signifies a faucet. The clouds stand for wherever the flows come from and go to i. Bathtub 1: Total amount of money in an account stock affects how much money comes into the account as interest. The stock level feeds back through a chain of signals and actions to control itself.

It is stabilizing, goal seeking, regulating and is called a Balancing Feedback Loop. Those elements include populations and economies.

When one loopdominates another, it has a stronger impact on behavior. Because systemsoften have several competing feedback loops operating simultaneously,those loops that dominate the system will determine the behavior.

Changing the length of a delay may or may not, depending on thetype of delay and the relative lengths of other delays make a large changein the behavior of a system. The entire stock is available at once, and can be extracted at any rate limited mainly by extraction capital. But since the stock is not renewed - the faster the extraction rate, the shorter the lifetime of the resource.

If they are extracted faster than they regenerate, they may eventually be driven below a critical threshold and become, for all practical purposes, nonrenewable. We pay too little attention to history. We are too fascinated by the events they generate pp.

We are not too skilled in understanding the nature of relationships pp. This presentation by Dr. Otto Scharmer of the Presencing Institute is especially helpful in understanding the theory.

Because it has been evolving and perfecting its systems for millions of years, nature can provide powerful examples of sustainable solutions.

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. 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. 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.

This simple theorem is easily visualized by imagining a bathtub: 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.

How to think in Systems? Great (and accessible, and short) book.

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. These diagrams are an important way to visualize and understand how a system of different elements is working together.

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.
