Domain engineering is the foundation for emerging “product line” software development approaches and affects the maintainability, understandability, usability, and reusability characteristics of similar systems. However, the existing domain engineering methods do not elicit information necessary for the component-based software development process in selecting and configuring appropriate components. In this paper, we suggest a method that systematically defines, analyzes and designs a domain to enhance reusability effectively in component-based software development (CBSD). We extract information objectively that can be reused in a domain from the requirement analysis phase. We sustain and refine the information, and match them to artifacts of each phase in domain engineering. Through this method, reusable domain components and malleable domain architecture can be produced. In addition, we demonstrate the practical applicability and features of our approach for a news information storage domain.
