Abstract
Based on the experience gained during the licensing process of a computer based protection system, a framework for the safety assessment process of software based systems is formulated. The framework is made in the form of an influence net, where the top nodes in the graph represent the basic information sources. This information is penetrated through the net down to the bottom node representing the final acceptance of the system. A particular investigation is made on the possibility to apply FMECA on proprietary software modules.
