Another difference seems to be the relevance of the participants in risk assessments. Any Hazard identification workshop that I was involved in had workface controllers involved in the process. After all we were the people who would ahve to implement/control anything that was devised.
We did not use outside consultants with vested interest and I would think the aviaiton industry is a little more adept at identifying risk than a building assessor. There seems to be a misconception that you need an "expert" to assess your risk. This is far from the truth and the concept of risk assessment.
We used a facilitator - always someone from an ATC background who had reveived formal training in risk management - and as many as 6 subject matter experts (just another phrase for the workface controller) - in each workshop and worked thorugh a series of 'what if' scenarios.
The example of the building assessor is not very relevant to an aviation risk management plan and embedded safety management system.
