Developing Problem Tree & Solution Tree

What is a Problem Tree? A problem tree provides an overview of all the known causes and effects to an identified problem.

Why do a Problem Tree There are often more than one cause to a problem, and you may not be able to overcome them all, so it is important to know if this will impact your project. A problem tree identifies the context in which an intervention is to occur, and starts to reveal the complexity of life.

The Process A problem tree is best completed with the project proponent and other stakeholders present. You may need anything from a couple of hours, to half a day or more depending on the complexity of your problem and the diversity of stakeholders present.

Steps to undertaking a problem tree Settle on the core problem Identify the causes and effects Develop a solution tree Select the preferred intervention 1. 2. 3. 4.

What does a Problem Tree look like?

The Core Problem A project should have a specific problem (eg. saving water inside the home) that it seeks to overcome if change is to occur. A vague or broad problem (eg. saving water) will have too many causes for an effective and meaningful project to be developed.

Identifying the causes and effects The core problem is placed at the centre of the tree. You then need to consider the direct causes to the problem. These are placed below the core problem. Each cause statement needs to be OUTPUTS written in negative terms. Financial incentives provided to The direct effects of the problem are placed households above the core problem.

Identifying the causes and effects You then need to consider the causes to the immediate causes- these are called secondary causes, and so on. You can do the same for the effects. You will likely need to move causes around, as Financial you decide whether they are a primary, incentives secondary or other cause. provided to OUTPUTS households

Lets look at an example

Project designs do not consider the full context. And now the effects There are not enough problem trees conducted. People do not know what a problem tree is. An example of a core problem People do not know how to do a problem tree. There are no easily accessible resources. Lets look at some causes… Resources are too hard to understand.

An example of a completed problem tree

Develop a solution tree A solution (also called objectives) tree is developed by reversing the negative statements that form the problem tree into positive ones. For example, a cause (problem tree) such as OUTPUTS “lack of knowledge” would become a means Financial such as “increased knowledge”. The objectives incentives tree demonstrates the means-end relationship provided to between objectives. households

An example of a completed solution tree

Select the preferred intervention This step is designed to allow the project team to select and focus an intervention on a preferred strategy. The solution tree may present a number of separate or linked interventions to solve a problem. Depending on project funding, time, and relevance, a planned intervention may not be able to tackle all the causes.

An example of selecting a preferred intervention

Select the preferred intervention If all the causes cannot be overcome by a project, or complementary projects, it is important to identify if any of the branches are more influential than others in solving a problem. This may impact on the success of your project. You can also consider the impact of other branches in your monitoring and evaluation.

Using the solution tree to inform your project design Effects Core Cause Cause The effects become your intermediate and long term outcomes The core can become your project goal or immediate outcome The causes/solutions become your activities and objectives
