Abstract

This article revisits the Three Phases Method (3PM) which was published in 2010 in this journal. The 3PM is aimed at outsourcing data mining to improve corporate performance. This follow-up work aims to provide more insight into the 3PM by describing every phase of the method in detail as Meta-Algorithmic Models, through descriptions of the activities and concepts of the method and visualising the process and deliverables in Process Deliverable Diagram notation to simplify adoption of the method by practitioners.

3Pm Revisited

As the name suggests, the 3PM consists out of three phases. In this section the roles that are available in the process are described, followed by a collection of Meta-Algorithmic Models as visual descriptions of each phase in which the main activities and deliverables of each phase are described (Spruit & Jagesar, 2016). The deliverables are notated as Process Deliverable Diagrams (PDDs), a process modelling language developed by van Weerd & Brinkkemper (2009), that are available in the paper of Vleugel et al. (2010). PDDs are chosen as a modelling technique because the language is used in the original paper by Vleugel et al. (2010) and because it provides a concise overview of all steps and deliverables in one model. In addition, the process and deliverables are respectively modelled using a flow-chart technique and an adaptation of UML class diagramming to facilitate easy understanding and shows a clear division of roles in the process. It is important to keep in mind that the 3PM is an iterative method, as can be seen in Figure 1. This section will continue describing the roles that can be adopted in executing the method, the main activities of each phase, the origin of the method and finally its strengths and weaknesses.

Roles

In the 3PM method there are two roles described by Vleugel et al. (2010): A case company, denoted by (C) in the coming sections, and a third party, denoted by (T), if both parties have to be involved CT is used as notation. The case company is the owner of the data on which data mining will be applied and in which the results will be implemented. The third party is the organisation to which the data mining is outsourced.
