Table 3: HMP-Coffee Summary Grid. Grid 1 analyzes the relationship Level: rows contain the HMP-Coffee brainstorming concepts and columns include the global concepts Production Cost, Market and Production volume. Grid 2 analyzes the generality Level: rows contain the HMP-Coffee brainstorming concepts and columns include generality levels: Very High Generality(vhg), High Generality(hg), Medium Generality (mg) and Specific(s). Cells represent the values assigned by experts to the relationships between columns and rows. Furthermore, the explainable name column contains new names by the 24 concepts. By levels (generality):  
* **Level 1 (Output variable)** includes profitability (vo). * **Level 2 (Global variables)** contains production cost (gv1), production volume (gv2), and market (gv3). * **Level 3 (Very High Generality)** contains management expenses (t21), investment in harvest time (t22), and investment in crop care activities (t23)
* **Level 4 (High Generality)** contains labor of the crop (t19), and investment on supplies (t20).
