The planning phase of a data project begins with forming a series of hypotheses, i.e., questions to confirm. A helpful way is to brainstorm the various ways in which a problem can manifest. We introduce mind maps to visualize the problem and the related measures to look at. Confirmatory analysis will be used at a later to confirm if the hypotheses are valid in contributing to the problem. The main purpose of this phase is to generate a series of items to analyze.
