< systems analysis > 1. The development and evolution of domain specific knowledge and artifacts to support the development and evolution of systems in the domain. Domain engineering includes engineering of domain models , components, methods and tools and may also include asset management .
2. The engineering process of analysing and modelling a domain, designing and modelling a generic solution architecture for a product line within that domain, implementing and using reusable components of that architecture and maintaining and evolving the domain, architecture and implementation models.
3. A reuse-based approach to defining the scope ( domain definition ), specifying the structure ( domain architecture ) and building the Assets (requirements, designs, software code, documentation) for a class of systems, subsystems or applications. Domain engineering can include domain definition, domain analysis, developing the domain architecture domain implementation.
