2. Complete E-P-V (Element-Parameter-Values) trees for all parameters

Using the grid suggested in figure 2, place all the parameters in their proper place in the EPV tree. When you move a parameter from its list to the EPV tree, this means that the cause-effect assertion is validated in both directions (satisfactory and unsatisfactory). Make sure that each parameter is taken into account in at least one polycontradiction (that it is not an orphan).
