Publisher Summary This chapter introduces a series of instructions that guides to take the next step depending on the results. This is called a methodology. Methodologies are made up of four types of “boxes” - Action Boxes, Discovery Boxes, Technique Boxes, and Example Boxes. Each box type has a different role in the methodology. Each box is exclusively labeled for reference and is grouped with similar boxes. Therefore, all the Action Boxes come first followed by the Discovery Boxes, then Technique Boxes, and finally Example Boxes. However, neither methodology can be read sequentially. This point bears repeating. The methodology is not a sequential document. In case anyone attempts to go through it in a sequential order, its consequences will be a complete chaos. There is no one path through the boxes. The essence of these methodologies is for a modeler or miner to take action, evaluate results, and take decisions on the basis of the results.
