Tree Techniques: The Tree Technique has variants of use, depending on the starting point:
- A defined or focused problem An undefined problem An objective to achieve or an idea to carry out.

APPLICATION OF THE METHOD WHEN THE PROBLEM IS DEFINED OR FOCUSED.

METHODOLOGY IN 5 STEPS
Map of involved
Who are INVOLVED?
People, institutions or social groups:
- affected by the problem or move in the environment of the problem OR can participate in the solution.
Participation of those involved
Based on the map of stakeholders, the project team designs and applies participatory strategies that promote the effective intervention of those involved in the processes of identification, proposal and commitment to the solution.

APPLICATION OF THE METHOD FOR UNDEFINED PROBLEMS
Summary of steps
- Build a tree of causes and effects Determine the central problem Adjust the Problem Tree Define objectives and adjust means-ends tree Generate alternative solutions.
STEP 1
Build cause and effect tree
Undefined problem (fuzzy)
A problem is not defined:
- When a group of people involved may have different views on the nature or magnitude of the problem felt. When a menu of problems has been identified around a shared but not delimited situation. When there is a "feeling" of negative or inconvenient effects but it is not clear what it is.
Undefined problem
Very surely we are facing an undefined problem, or diffuse, when we hear expressions like these:
- "Something is wrong" "We feel good" "Our income has decreased" "Systems are not working" "Services are not reaching us" "The community is desperate" "Our children are not in good health"
Build cause and effect tree
Map of involved
Participation of those involved
- Identification of problems according to the perceptions of those involved Hypothesis chaining Identification of critical nodes Selection of the Central Problem.
Example:
Harvest and post-harvest problems perceived by a farming community.
As a result of a first exchange workshop, a list of the main 15 problems associated with the harvest and post-harvest processes that those involved identified was obtained.
A card was produced for each problem.
