Taking a systems thinking approach to problem solving

Systems thinking is an approach that considers a situation or problem holistically and as part of an overall system which is more than the sum of its parts. Taking the big picture perspective, and looking more deeply at underpinnings, systems thinking seeks and offers long-term and fundamental solutions rather than quick fixes and surface change.

Whether in environmental science, organizational change management, or geopolitics, some problems are so large, so complicated and so enduring that it’s hard to know where to begin when seeking a solution.

A systems thinking approach might be the ideal way to tackle essentially systemic problems. Our article sets out the basic concepts and ideas.

What is systems thinking?

Systems thinking is an approach that views an issue or problem as part of a wider, dynamic system. It entails accepting the system as an entity in its own right rather than just the sum of its parts, as well as understanding how individual elements of a system influence one another.

When we consider the concepts of a car, or a human being we are using a systems thinking perspective. A car is not just a collection of nuts, bolts, panels and wheels. A human being is not simply an assembly of bones, muscles, organs and blood.

In a systems thinking approach , as well as the specific issue or problem in question, you must also look at its wider place in an overall system, the nature of relationships between that issue and other elements of the system, and the tensions and synergies that arise from the various elements and their interactions.

The history of systems thinking is itself innately complex, with roots in many important disciplines of the 20th century including biology, computing and data science. As a discipline, systems thinking is still evolving today.

How can systems thinking be applied to problem solving?

A systems thinking approach to problem solving recognizes the problem as part of a wider system and addresses the whole system in any solution rather than just the problem area.

A popular way of applying a systems thinking lens is to examine the issue from multiple perspectives, zooming out from single and visible elements to the bigger and broader picture (e.g. via considering individual events, and then the patterns, structures and mental models which give rise to them).

Systems thinking is best applied in fields where problems and solutions are both high in complexity. There are a number of characteristics that can make an issue particularly compatible with a systems thinking approach :

The issue has high impact for many people.
The issue is long-term or chronic rather than a one-off incident.
There is no obvious solution or answer to the issue and previous attempts to solve it have failed.
We have a good knowledge of the issue’s environment and history through which we can sensibly place it in a systems context.

If your problem does not have most of these characteristics, systems thinking analysis may not work well in solving it.

Areas where systems thinking is often useful include health, climate change, urban planning, transport or ecology.

What is an example of a systems thinking approach to problem solving?

A tool called the iceberg mode l can be useful in learning to examine issues from a systems thinking perspective. This model frames an issue as an iceberg floating in a wider sea, with one small section above the water and three large sections unseen below.

The very tip of the iceberg, visible above the waterline, shows discrete events or occurrences which are easily seen and understood. For example, successive failures of a political party to win national elections.

Beneath the waterline and invisible, lie deeper and longer-term trends or patterns of behavior. In our example this might be internal fighting in the political party which overshadows and obstructs its public campaigning and weakens its leadership and reputation.

Even deeper under the water we can find underlying causes and supporting structures which underpin the patterns and trends.

For our failing political party, this could mean party rules and processes which encourage internal conflict and division rather than resolving them, and put off the best potential candidates from standing for the party in elections.

The electoral system in the country may also be problematic or unfair, making the party so fearful and defensive against losing its remaining support base, that it has no energy or cash to campaign on a more positive agenda and win new voters.

Mental models

At the very base of the iceberg, deepest under the water, lie the mental models that allow the rest of the iceberg to persist in this shape. These include the assumptions, attitudes, beliefs and motivations which drive the behaviors, patterns and events seen further up in the iceberg.

In this case, this could be the belief amongst senior party figures that they’ve won in the past and can therefore win again someday by repeating old campaigns. Or a widespread attitude amongst activists in all party wings that with the right party leader, all internal problems will melt away and voter preferences will turn overnight.

When is a systems thinking approach not helpful?

If you are looking for a quick answer to a simple question, or an immediate response to a single event, then systems thinking may overcomplicate the process of solving your problem and provide you with more information than is helpful, and in slower time than you need.

For example, if a volcano erupts and the local area needs to be immediately evacuated, applying a thorough systems thinking approach to life in the vicinity of an active volcano is unlikely to result in a more efficient crisis response or save more lives. After the event, systems thinking might be more constructive when considering town rebuilding, local logistics and transport links.

In general, if a problem is short-term, narrow and/or linear, systems thinking may not be the right model of thinking to use.

A final word…

The biggest problems in the real world are rarely simple in nature and expecting a quick and simple solution to something like climate change or cancer would be naive.

If you’d like to know more about applying systems thinking in real life there are many online resources, books and courses you can access, including in specific fields (e.g. FutureLearn’s course on Understanding Systems Thinking in Healthcare ).

Whether you think of it as zooming out to the big picture while retaining a focus on the small, or looking deeper under the water at the full shape of the iceberg, systems thinking can be a powerful tool for finding solutions that recognize the interactions and interdependence of individual elements in the real world.

A number of problem-solving techniques are listed below: [1]

Abstraction : solving the problem in a model of the system before applying it to the real system
Analogy : using a solution that solved an analogous problem
Brainstorming: (especially among groups of people) suggesting a large number of solutions or ideas and combining and developing them until an optimum is found
Divide and conquer : breaking down a large, complex problem into smaller, solvable problems
Hypothesis testing : assuming a possible explanation to the problem and trying to prove (or, in some contexts, disprove) the assumption
Lateral thinking : approaching solutions indirectly and creatively
Means-ends analysis : choosing an action at each step to move closer to the goal
Method of focal objects : synthesizing seemingly non-matching characteristics of different objects into something new
Morphological analysis : assessing the output and interactions of an entire system
Reduction : transforming the problem into another problem for which solutions exist
Research : employing existing ideas or adapting existing solutions to similar problems
Root cause analysis : eliminating the cause of the problem
Trial-and-error : testing possible solutions until the right one is found
