+ | === The Tragedy of the Commons === | ||
+ | The Tragedy of the Commons provides unique insights into the effect that an un-systemic approach to organizational structure can have on overall, long-term performance. | ||
+ | |||
+ | The commons is something or someone that presents a common resource. It can be various natural resources. In an organization, it can be people, material, space, tools, etc. It can be anything, that is simultaneously made available to multiple people (or teams in organization). | ||
+ | |||
+ | Each person or team claims their share of the commons within the context of the goals and objectives that they have set for themselves. They regard the commons as being uniquely available for their own purposes. Although their lack of awareness of the demands others place on the commons are not the result of thoughtless disregard, the effect on the commons is the same. | ||
+ | |||
+ | As each person or team increases their demands and expectations of the commons in the name of their own goals, the commons gets under steadily increasing pressure to perform. In the case of commons such as materials or space, there is no conscious awareness of increased demand, but the concrete, physical limitations have no elasticity, and the satisfaction of people or teams placing demands on the commons erodes. | ||
+ | |||
+ | This archetype identifies the causal connections between individual actions and the collective results (in a closed system). It hypothesizes that if the total usage of a common resource becomes too great for the system to support, the commons will become overloaded or depleted and everyone will experience diminished benefits. <ref name="braun">Braun, William.

The Tragedy of the Commons is one of system archetypes. It is an economic theory describing a system with shared resource where the actors act independently according to their self-interest. Draining of the resource can cause their actions to behave contrary to the common good. The Tragedy of the Commons became well known after an article by ecologist Garrett Hardin was published in 1968.

Introduction
You live in a smaller city where you own some land. As a landowner, you have the rights to use the water pumped up from wells on your land. Whenever you are in a need of water, you go and get it. As your family grows, you naturally need more water. But it's just few more people and there is enough water in your well. There are many other landowners in your city and each one manages his own water consumption. As your city and its population is growing, water usage rises as well. What you may not realize is the fact, that all the water from different wells throughout the whole city is part of a regional groundwater aquifer, so each landowner is pulling water from the same pool. After continual long-term growth of the water consumption, the city’s water supply reached levels that left the aquifer vulnerable to saltwater intrusion from the nearby ocean. Now the city is facing potential water shortages and possible destruction of the renewable water resource the city depended on. [2]

System Archetypes
System Archetypes describe common patterns of behavior that we can find in complex systems. They are part of a larger topic of System Dynamics.
There is a number of different System Archetypes. Yet there are two basic structures and all the other archetypes are different combinations of the two. The two basic structures are The Balancing Loop and The Reinforcing Loop. The Balancing Loop represents an objective not yet met, referred to as a gap between the current state and a desired state. It is common for balancing loops to have one or more delays. For example, there is usually a delay after a change is introduced and before it starts having a visible effect. The Reinforcing Loop promotes an effect or action. An example can be a savings account in which the interest earned is added to the principal, which itself earns more interest, which adds to the principal, and the cycle repeats. [3]
As it was already said, The Tragedy of the Commons is one of the System Archetypes. Here are some other System Archetypes examples:
- Limits to Growth
- Accidental Adversaries
- Drifting Goals
- Escalation
- Fixes That Fail
- Growth and Underinvestment
- Shifting the Burden
- Success to Successful
The Tragedy of the Commons
The Tragedy of the Commons provides unique insights into the effect that an un-systemic approach to organizational structure can have on overall, long-term performance.
The commons is something or someone that presents a common resource. It can be various natural resources. In an organization, it can be people, material, space, tools, etc. It can be anything, that is simultaneously made available to multiple people (or teams in organization).
Each person or team claims their share of the commons within the context of the goals and objectives that they have set for themselves. They regard the commons as being uniquely available for their own purposes. Although their lack of awareness of the demands others place on the commons are not the result of thoughtless disregard, the effect on the commons is the same.
As each person or team increases their demands and expectations of the commons in the name of their own goals, the commons gets under steadily increasing pressure to perform. In the case of commons such as materials or space, there is no conscious awareness of increased demand, but the concrete, physical limitations have no elasticity, and the satisfaction of people or teams placing demands on the commons erodes.
This archetype identifies the causal connections between individual actions and the collective results (in a closed system). It hypothesizes that if the total usage of a common resource becomes too great for the system to support, the commons will become overloaded or depleted and everyone will experience diminished benefits. [4]
Behavior Over Time
Any time a declining trend is seen in the overall performance of each part of the system even as it increases its demand on common resources, there is a good possibility that a Tragedy of the Commons is taking place. This is often accompanied by puzzlement, as each party placing demands on the system cannot understand why their demands are not being met, which typically results in the party increasing its demands yet further. This may continue until the commons collapses. [4]
Consequences in Organization
There can be several consequences as aggregate performance of the commons falls. Here are possible consequences of the problem in an organization:
- Individual or team performance declines as the erosion of the commons affects their ability to meet individual goals and objectives.
- Aggregate organizational performance erodes as the interaction and interdependency of multiple individual and/or team performance begins to reflect the declining performance of the individuals or teams.
- Organizational goals themselves begin to erode and to reflect the diminished ability of the commons to support the goals and objectives of the individuals and teams that depend on the commons.
- The commons itself deteriorates as a valued and valuable resource to the point where it is regarded as a cause of failure rather than success.
Applications and Solutions
There are two large areas where The Tragedy of the Commons can be applied. One of them is environment (and common land). In this case, the commons is any shared or unregulated resource, for example atmosphere, oceans, rivers, fish stocks, etc. The other case is the application of The Tragedy of the Commons in an organization and its environment.
Environment
There is a group of problems for which The Tragedy of the Commons can apply. Those are the problems that have no technical solution to them. A technical solution can be defined as one that requires a change only in the techniques of the natural sciences, demanding little or nothing in the way of change in human values or ideas or morality. A member of this class of problems is the population problem. The desired solution for the population problem is one that avoids the evils of over-population without giving up any of the privileges we enjoy. This solution cannot be found, the population problem cannot be solved in a technical way. An agreement needs to be created, which proposes a change in the current behavior. [1]
Organization
The System Archetypes are highly effective tools for gaining insight into patterns of behavior, themselves reflective of the underlying structure of the system being studied. The archetypes can be applied in two ways - diagnostically and prospectively.
Diagnostically, archetypes help managers recognize patterns of behavior that are already present in their organizations. Archetypes are also useful prospectively for planning. As managers formulate the means by which they expect to accomplish their organizational ends, the archetypes can be applied to test whether policies and structures under consideration may be altering the organizational structure in such manner as to produce the archetypal behavior. If managers find this to be the case, they can take remedial action before the changes are adopted and embedded in the organization’s structure.
The archetype can be used to help connect the long-term effects of individual actions to the collective outcome, and develop measures for managing the common resource more effectively.
Prescriptive Action can consist of these steps:
- Establish methods for making the cumulative effects of using the common resource more real and immediate to the individual players.
- Re-evaluate the nature of the commons to determine if there are ways to replace or renew (or substitute) the resource before it becomes depleted.
- Create a final arbiter who manages the use of the common resource from a whole-system level.
Seven Action Steps can be as follows:
- Identify the “commons”. What is the common resource that is being shared?
- Determine incentives. What are the reinforcing processes that are driving individual use of the resource?
- Determine the time frame for reaping benefits.
- Determine the time frame for experiencing cumulative effects of the collective action.
- Make the long-term effects more present. How can the long-term loss or degradation of the commons be more real and present to the individual users?
- Reevaluate the nature of the commons. Are there other resources or alternatives that can be used to remove the constraint upon the commons?
- Limit access to resources. Determine a central focal point - a shared vision, measurement system, or final arbiter - that allocates resources based on the needs of the whole system.
In many respects the Tragedy of the Commons is a classic example of reductionistic thinking.[4]
Example
IT resources are typically organized into a “commons” department, with each part of the organization seeking their support on an as-needed basis. Since separate parts of the organization typically do not keep track of the IT problems in other parts of the organization, it is fairly common for each part of the organization to see the IT department as “its own”. When the IT department is crushed under the weight of all the demands placed upon it, its performance for every department begins to erode or fail. [4]
There are two parties that place demands to the IT department – Admin and Medicine. As net gains for Admin or Medicine grow, their demands for IT grow and the total number of demands to IT grows. As the total number of demands to IT exceeds the capacity of the IT department, its efficiency falls. Total demands either need to be reduced or IT resources raised. Either way, some kind of coordination and agreement needs to take place.
Exercise
Now the exercise will be similar to the example above. You are an Admin in a company and you place demands to the company’s IT department. As your productivity rises, your demands for IT rise as well. There is marketing department in the company that places demands to IT as well.
- Create the Casual Loop Diagram for the example.
- There was a change in the company and the IT department now takes demands from Management as well. Create the Casual Loop Diagram for the modified case as well.
