Especially important is its connection with the Nonfunctional Requirements (NFRs) that may affect certain areas where “alternative design approaches” are sometimes used to satisfy the corresponding NFRs.ĭomain modeling also provides the Agile organization with opportunities for use of Agile-friendly design patterns and approaches that enhance velocity over the long term. In SAFe, domain modeling connects to backlog items at the Team, Program, Large Solution and Portfolio levels and provides a common language for the entire organization. Driven in part from object-oriented design approaches, domain modeling envisions the solution as a set of domain objects that collaborate to fulfill system-level scenarios.
Because there is often a gap between understanding the problem domain and the interpretation of requirements, domain modeling is a primary modeling area in Agile development at scale. Derived from an understanding of system-level requirements, identifying domain entities and their relationships provides an effective basis for understanding and helps practitioners design systems for maintainability, testability, and incremental development. Essentially, all models are wrong, but some are useful.ĭomain Modeling is a way to describe and model real world entities and the relationships between them, which collectively describe the problem domain space.
