Defining a Software Process Improvement-Based Methodology for Embedded Systems Development

While software process improvement methods appear to be well suited for embedded systems development, their use has not become an organized practice. In the same way as that of software development, the embedded systems development could be failing due a bad management in the development process. In this paper we introduce the SPIES methodology that integrates the CMMI-DEV v1.2 Level 2 process areas to specify a process for developing embedded systems. This methodology incorporates principles to support the lack of management and improve the process specification. To illustrate this methodology, we design an experimental system to manage a traffic light system.
