Conflict of Interest or is the result known before the enquiry?
You would think that the management of any company that was serious enough to commence an investigation into why their product is failing in the market would employ an independent group to pursue answers, not a person that was responsible for applying the policies that lead to the failure in the first place.
Imagine if, following a serious incident involving injury to passengers or sever damage to an aircraft, the investigation was lead by the Captain and crew responsible. Conflict of interest? Never.
Within Qantas it seems that outside help is only sought to cull not to develop.
