The document discusses a presentation on categorizing failures given by Karen Rayment on May 5, 2015. It covers: 1) Defining failures from a legal perspective and putting up "walls" between failures and their effects. 2) Considering product lifecycles to help clarify remedies and artifacts of catastrophic failures' business and human impacts. 3) A case study where contaminated glue on a printed circuit board was found to be the cause of an intermittent fault through microscopy and spectroscopy, legally categorizing it as a manufacturing defect.
