Instantiate hazardous failures argument pattern

This activity requires as input the hazardous failures argument pattern ([DD]), as well as the relevant artefacts from previous activities ([BB], [Q]and [Y]). The activity uses these artefacts to create an instantiated hazardous failures argument for the AS ([EE]) which demonstrates that the potentially hazardous failures identified at each tier are acceptably managed.
