After months of delays and several postponements, the M1 Grayston Bridge inquiry resumed on Tuesday 26 September – only to be postponed promptly once again. In the weeks prior to the resumption, the Department of Labour’s Teboho Thejane said, ‘Families that have been waiting to hear all the arguments so that they can put this matter to rest, to hear what has happened and if there are any people that are responsible for this. But at this point… we’re waiting to hear the arguments.’
Under modern occupational risk management (ORM), the primary differences between risk assessment and risk measurement are:
- the types of data used, and
- the way parameters are derived.
Where sufficient hard data is available, risk measurement is often more reliable than risk assessment. However, developing a theoretically valid method of combining hard data and soft data is a very difficult process (OpRisk Advisory and Towers Perrin, 2010).
