Problem Tree Analysis: the Basics and Example
In this article, we discuss problem tree analysis, also known as problem tree analysis: an effective way to get to the bottom of complex problems in a structured way. You will discover what exactly a problem tree entails, why this approach is valuable for project management and policy development, and how to create a problem tree yourself. We also briefly cover problem structure analysis, a similar approach that lets you look at problems in a different way. After reading, you will have the ability to independently create a problem tree that supports you in creating sustainable and specific solutions. Have fun reading!
What is a problem tree analysis
A problem tree analysis is a visual approach to get a better picture of a problem in a structured way. It starts with a key problem, the “trunk” of the tree, then studies the underlying reasons (the roots) to finally visualise the consequences (the branches). By clearly highlighting these causal relationships, you get a better understanding of the real bottlenecks. The aim is to ultimately find a solution that addresses the root of the problem, rather than just treating the symptoms.
This analysis helps to gain shared insights, especially in situations involving multiple stakeholders. The approach encourages both structure in thinking and collaboration.

The problem tree is especially valuable in complex issues involving several factors. Instead of immediately striving for solutions, it allows you to study the underlying issues first.
An added benefit is that the approach encourages cooperation: putting the tree together creates shared understanding and support for further steps. In addition, the tree is flexible: you can revise it as you adjust insights. It is therefore not a temporary tool, but an active tool that you can always pull out during any process going on within the organisation.
Problem structure analysis: an alternative view
Problem structure analysis is similar to the problem tree, but offers a different way of looking at complex problems. Whereas the problem tree works with a hierarchical model from root (causes), through the trunk (the core problem), to the branches (consequences), problem structure analysis takes a network approach.
Instead of one central line from cause to effect, in this method you map multiple factors that influence, reinforce or counteract each other. Think chain reactions and feedbacks.
This approach is especially valuable when dealing with complex, dynamic problems involving many different factors and influences.
A problem tree is more likely to be used when you want to structure the problem in an orderly way, especially in the early stages of a project. It helps to agree on what the problem is and where to act. A problem structure analysis is just right for situations where there are many interdependencies and you want to investigate how changes in one part of the system affect the other.
How to create a problem tree?
Creating a problem tree starts by focusing on the core problem. This is the problem you want to analyse or address. You then examine what the immediate causes of this problem are and place these under the core problem in the tree. Then you ask what happens if the problem is not addressed. In this way, the consequences appear as the so-called branches on paper. You place these above the core problem. This creates a hierarchical structure of cause (roots), problem (trunk) and consequences (branches).
The purpose of a problem tree is to clarify, together with those involved, the core of the problem and where possible interventions are most effective. It is a powerful tool to jointly reach understanding in complex situations.
A problem tree analysis example
A good example of a problem tree shows how to map a complex issue in an orderly way. Suppose you are investigating why young people do not exercise enough. At the centre of the problem tree is then the core problem: ‘Lack of physical activity among young people’. Underlying causes could be: ‘Too few sports facilities’, ‘Lack of motivation’ and ‘Insufficient education in schools’. Consequences can range from ‘Increased obesity’ to ‘Poor mental health’.
Once you have drawn up the problem tree, you can use it as a starting point for devising solutions. The underlying causes give direction to possible interventions. This allows you to plan targeted actions, such as improving sports facilities, developing information campaigns or setting up behaviour change programmes. The problem tree also helps to set priorities: which causes can you tackle first for the most effect?
Common mistakes when making a problem tree
Although the problem tree analysis is a powerful tool, in practice there are often mistakes in it that affect the quality of the analysis. A common mistake is confusing symptoms with causes. This leaves the analysis superficial and does not reveal deeper layers of problems.
Teams also sometimes move too quickly to solutions without properly identifying the problem. This can lead to measures that do not address the core problem.
In addition, we often see that causes and effects are mixed up, so the logic of the tree is lost. Another pitfall is that too few stakeholders are consulted when drawing up the problem tree, leading to important perspectives and causes being overlooked. Finally, it is important to ask sufficient questions about underlying causes so that you do not get stuck in general terms.
The power of working visually
Working visually, as you do with a problem tree, helps make complex issues clear. Connecting causes, consequences and the core problem visually creates a clear overall picture. In just one glance, you can see the broad outlines of the story. This increases joint understanding within teams and prevents important aspects from being overlooked.
Moreover, a visual representation creates more support, because all those involved can literally see how different factors are connected. This makes it easier to make choices and set priorities together. Visualisations also stimulate creative thinking and invite discussion and addition.
Additional tips for creating an effective problem tree
Want to get the most out of your problem tree? Then start small: focus first on clearly formulating the core problem. Then use post-its or an online whiteboard tool, so you can easily rearrange causes and effects as new insights emerge. Preferably work in a group: different perspectives often provide a fuller picture.
Also pay attention to your language: formulate each element as a factual, observable problem, and avoid vague or prescriptive terms. Finally: take pictures or save your digital version well, so you can use it later as a starting point for a solution-oriented brainstorm.
Problem tree in participatory sessions
The problem tree is also a powerful tool during participatory work sessions with stakeholders or project teams. By creating a problem tree together, you give different stakeholders the opportunity to contribute their perspective and knowledge. This not only promotes understanding of each other’s points of view, but also increases support for the final problem definition and subsequent solutions.
Moreover, working visually helps to keep complex discussions manageable and get to the heart of the problem together faster. This makes the problem tree very suitable for use in workshops, brainstorming sessions or policy projects.
Conclusion
Get to work yourself by drawing up a problem tree for your issue. Start by sharply formulating the central problem and then work out the underlying causes and possible consequences step by step.
Whether you choose the more hierarchical problem tree or the network-oriented problem structure analysis: both methods help you develop targeted solutions that really connect to the core of the problem. This approach prevents you from fighting symptoms and increases the chances of sustainable change.
With a well thought-out problem tree, you therefore lay a solid foundation for successful projects, policies or interventions.
It’s Your Turn
Get to work yourself by drawing up a problem tree for your issue. Start by sharply formulating the central problem and then work out the underlying causes and possible consequences step by step. Involve colleagues or other stakeholders to gather different perspectives and together arrive at a shared picture.
Perhaps other thinking frameworks also help. For instance, the CATWOE model offers valuable tools to systematically look at different interests and perspectives within your organisation. And Weggeman’s ESH framework helps you to determine at which level in the organisation a problem is actually taking place – essential to arrive at targeted and effective solutions. Both models are aimed at addressing complex issues within organisations and can nicely complement your problem tree analysis.
