The investigation of reuse has a long history, eventually maturing into the "build by integration" paradigm. Meanwhile, component technologies also improved along with engineering practices. What is missing is a methodology that uses components within such a paradigm, thus bridging the gap. The authors propose a model devoted to complete component orientation, rather than modifying object-oriented approaches to accommodate components. They investigate component-based technologies to address new needs and, consequently, to integrate adequate practices toward a consistent process model.
