A risk-driven design model for embedded system

Embedded systems are becoming a hot issue for many appliances. However, the development of embedded systems faces the challenge of high risks from market pressures and lack of domain expertise. We introduce a risk-driven model for embedded system development. Driven by risk evaluation, the model guides the embedded system development in a module-based approach. Moreover, a risk evaluation framework composed of three-dimensional metrics is provided with the model to address and track the development risk, including metrics for economy, personnel and technology. A case study is provided to demonstrate how the model and framework are applied.
