Two Loop Model

The Berkana Two Loop Model, as described by Margaret Wheatley and Deborah Frieze, is a map for creating change in living / social systems. It illustrates the concept that change can intentionally be created by strategically using emergence.

The upper loop represents the existing system. All living systems go through a period in which they rise, peak and then move into decline. Stewards of the existing system try to maintain the health of the system for as long as possible. As systems near their peak, signs of turbulence may appear leading to decline. As decline continues the need to provide hospice care grows. Hospice care can help the system end gracefully, making sure that as it declines, damage is minimized and learning is maximized.

Emerging from the decline of an old system can be a new system illustrated by the lower loop. Turbulance in the existing system leads to "walk outs" from the old system.  These innovators or trailblazers turn their backs on the existing system so they can create something new.  Innovators tend to work in isolation, are invisible and are mostly ignored.  If they remain isloated, they will likely fail.

Instead, if the innovators are connected, they can form networks and build trust to allow for a stronger base and a sharing of knowledge.  When networks are nourished they can become communities of practice. Connecting and nourishing these networks and communities is key to the growth of the new system.  They are the fertile ground in which the new system can take root.  This is the space in which illuminators can shine a light on whats possible and help a community to become a system of influence.  

The transition from the old to the new is a critical phase where resources and people start to flow towards the innovations that have proven to be effective. It’s in this space that the old system can offer its resources to help the new system grow.
