An Approach Towards Global Standardization of the Risk Matrix

One of the more common approaches used in all space organizations is a risk matrix. However, also risk matrices suffer from parallel developments and change in presentation and, more important, in different scales of the axes, making comparisons impossible. Moreover, there is a clear need for different scales, in particular in terms of probabilities, for human versus robotic missions. For these reasons, a standard matrix will be proposed as the results of a comparison between the different matrices. Furthermore, a quantification method to compare the risk between different projects will be introduced.
