Using words and phrases are part of normal business communications. The analysis that focuses on the way an organization uses these words and phrases is called Semantic analysis. But, the analysis does not include the definitions of these words. Semantic analysis uses the words and phrases looking for similarities and differences in how people describe their organization. These words and phrases are grouped into structures or models. A typical example is a process model. A process model is a descriptive model because it explains the organization’s actions in word and phrases (Market Product, Sell Product, Order Product, Ship Product, etc.). There are many other types of models in the organization that are descriptive not just process models. For example, an organization model (usually an organization chart), a chart of accounts, a bill of materials, a distribution network diagram (with words in them), geographic models showing where things are produced, shipped and so on, are all descriptive models. Keep in mind, even diagrams have words and phrases in them and are organized in some manner and are a model. This is what a process flow is.
