Hierarchical organisation of objectives
1) Identify the overall objective.
2) Clarify its meaning with more specific sub-objectives. Add the sub-objectives to the next level of the hierarchy.
3) Continue recursively until an attribute can be associated with each lowest level objective.
4) Add the decision alternatives to the hierarchy and link them to the attributes.
5) Iterate the steps 1- 4, until you are satisfied with the structure.
