Systems Archetypes and Their Application

Systems archetypes are common and usually reoccurring patterns of behavior in organizations.  These patterns almost always result in negative consequences.

Systems archetypes were first studied in the 1960s and 1970s by Jay Forrester, Dennis Meadows, Donella Meadows and others in the nascent field of systems thinking.

In his popular 1990 book, The Fifth Discipline: The Art and Practice of the Learning Organization, Peter Senge explored systems archetypes and, along with Michael Goodman, Charles Kiefer, and Jenny Kemeny, documented the most common set of patterns of behavior in organizations that have the tendency of reoccurring. These systems thinking researchers leveraged the annotations of John Sterman, a pioneer in system dynamics. The structures and graphical language of system dynamics allowed Senge and his colleges to document these common systems archetypes and make them accessible to the average reader.

Eight systems archetypes and their storylines

The eight, most common systems archetypes are: 

  1. Fixes that FailA solution is rapidly implemented to address the symptoms of an urgent problem. This quick fix sets into motion unintended consequences that are not evident at first but end-up adding to the symptoms.
  2. Shifting the BurdenA problem symptom is addressed by a short term and a fundamental solution.  The short term solution produces side effects affecting the fundamental solution.  As this occurs, the system’s attention shifts to the short term solution or to the side effects.
  3. Limits to SuccessA given effort initially generates positive performance.  However, over time the effort reaches a constraint that slows down the overall performance no matter how much energy is applied.
  4. Drifting GoalsAs a gap between goal and actual performance is realized, the conscious decision is to lower the goal.  The effect of this decision is a gradual decline in the system performance.
  5. Growth and UnderinvestmentGrowth approaches a limit potentially avoidable with investments in capacity.  However, a decision is made to not invest resulting in performance degradation which results in the decline in demand validating the decision not to invest.
  6. Success to the SuccessfulTwo or more efforts compete for the same finite resources.  The more successful effort gets a disproportionately larger allocation of the resources to the detriment of the others.
  7. EscalationParties take mutually threatening actions which escalate their retaliation attempting to “one-up” each other.
  8. Tragedy of the CommonsMultiple parties enjoying the benefits of a common resource do not pay attention to the effects they are having on the common resource.  Eventually, this resource is exhausted resulting in the shutdown of the activities of all parties in the system.

The set of common systems archetypes have their own unique causal storyline.  This storyline is universal and can be applied to the understanding of individual manifestations inside organizations. For instance, the “systems that fail” archetype has the “squeaky wheel” as its main storyline. In this archetype, a quick fix is applied to a pain point (or “squeaky wheel”) to reduce its symptom and the “noise” generated by it. The storyline gets complicated when the unintended effects of the quick fix become consequential. These effects start to add to the problem symptoms making the quick fix less or totally ineffective.

Aside from a storyline, systems archetypes have a structure. This structure is comprised of a number of mostly endogenous variables and feedback loopsone or more, of which, contains a delay that usually contributes to the unintended consequences of the behavioral pattern.  Endogenous variables are those that form part of the feedback loops that both modify and are modified by other variables. Three of the common eight systems archetypes“limits to success,” “growth and underinvestment,” and “tragedy of the commons”)contain endogenous variables that act as external constraints to these systems. The structure of systems archetypes is depicted through causal loop diagrams, a tool from the field of system dynamics. The picture in this posting shows the structure of the “fixes that fail” archetype. This structure has three variables: problem symptom, the quick fix, and the unintended consequence. The flow between the fix and the unintended consequence has a delay and the main reason for the existence of the archetype. Two feedback loops are present in this structure: a balancing loop for the quick fix and a detrimental reinforcing loop for the manifestation of the unintended consequence.

Applications for systems archetypes

Systems archetypes can be used as a diagnostic tool to better understand the dynamics of a specific set of behaviors that have manifested an unwanted condition.

The theory behind systems archetypes is that situations with unwanted results or side effects can be mapped to the common behavior models. Given the knowledge available about systems archetypes, problem-solvers in general can apply its principles and arrive at a rich diagnosis of a situation and plan a recovery.  The knowledge base on systems archetypes provides guidelines for determining what archetype is at play and, once identified, how to approach an intervention. 

From a proactive perspective, systems archetypes can be an important part of planning. A variety of strategies can be tested through the lens of archetypes to identify potential pitfalls and address them in the planning stages when they are easier to tackle. Additionally, systems archetypes provide a language to communicate among members of an organization regarding how a particular system is expected to perform. Unintended consequences in systems archetypes are well known and can be translated into potential or realized consequences. Having a language to document, communicate, and analyze behaviors provides a useful and consequential framework for dealing with changes necessary to prevent or eliminate negative behavioral patterns. Moreover, once the particulars of systems archetypes are mastered by members of an organization, their knowledge can be leveraged to build robust systems immune to their side effects.
