files/images_static/user.jpg Private and public sector regional, urban or sectoral planners.

A problem tree is used to:

  • Provide a guiding rationale for systems design and evaluation,
  • Indicate how one or more problems are the causes of a higher level problem (i.e. the effect),
  • Shows how problems are actually interrelated,
  • Highlights problems that need to be tackled consecutively to resolve the main constraint,
  • Provides an objective basis for monitoring and evaluating changes at a later stage,
  • Helps to assess the level of effort and later on impact a project will have to achieve to overcome the problems.

The materials needed are a surface on which to draw (newsprint, paper, chalkboard or the ground) and markers, pens or chalk.
