These patterns are made explicit through the generation of theoretical memos as the analysis proceeds,2. A substantive theory is generated when the researcher can define core categories in the data and important patterns of relationships between categories, that apply across data samples. These are related together by means of code integration to derive families of codes, or code splitting to derive sub-categories.

Data are categorized (or coded) according to an emergent set of categories that define key elements of the situation. The Grounded Theory method is based upon Glaser and Strauss (1967) and requires two key process elements, 1. A theory that is generated from patterns in, and relationships between, elements of the data collected, rather than based upon extant theories of action.
