For example, an agile project will likely use user stories as opposed to use cases. A reporting or analytics project will likely use data models, including a data dictionary and report tables. A system migration project will probably have scope models such as an ecosystem map or context diagram, as well as data models like a data dictionary and a business rules catalog. Early in a project, business analysts usually create context diagrams, ecosystem maps, and high-level process flows. Later in a project, business analysts may create state models, decision models, and user interface models. A project that involves automating operational functions benefits from process models to elicit information about how work is currently conducted and how work will be performed after the automation is implemented.

It is helpful to use more than one model, because the models complement one another and enable analysis of the project from different perspectives. For example, a data dictionary describes attributes of the business data objects and those data objects are also reflected in an entity relationship diagram. The allowed transitions on a state diagram are reflected in one or more process models. Cross-checking models against each other will help find gaps, unnecessary information, and potentially missing requirements.
