The 5 Whys
What: A simple tool to analyse the root causes of a given problem or challenge to understand how a project or programme should be designed to achieve the most impact.
Why: Diagnosing root causes requires that we ask – and try to answer – explanatory questions. These often start with the word ‘why’ and are framed in a way that positions one thing in relationship to another. For example, Why are people hungry when there is food available at the market? The 5 Whys method helps uncover problems, as well as eliminate unfounded or preconceived assumptions, by having the participants define a problem, then asking the question ‘why’ five times, often using the resulting explanation as a starting point for creative problem solving. In essence, the 5 Whys is a fast-paced version of the problem tree analysis.
When: This tool is great to apply during your exploratory phase, for example, after your needs assessment, to inform what part of a problem you should focus on to design the most impactful project.
