Process flow for end-to-end segmentation.. This pathway captures the overall and detailed steps and decision points, as well as target outputs, at each step from conceptualization to research design, implementation, analysis, and targeting. It is meant to assume the maximum workload for a program, where a de novo data set needs to be generated through primary research. Other scenarios are possible. For example, after defining a goal and structuring potential drivers, programs may find they can use existing data sets, in which case they might jump straight to cluster analysis. In any case, critical steps are interlinked and depend strongly on each other. They should therefore be considered together from the start.

Figure 1. First, dimensionality reduction of the data ensured the cluster analysis was happening on relevant variables.
