It particularly focuses on analysing the system'models building activities defined as Software Process Modeling and tries to lead to a response to problems such as: - Is it possible to enhance the dependability characteristics of the system by using a development environment where constraints about the development activities can be expressed and enacted? - Which operation could be automated in a critical system development environment leading to a better dependability. Early activities in the system life cycle related to dependability (such as preliminary hasard analysis) are
