Global differences is appetite for use of external consultants to support DDs

The concept of Due Diligence has emerged over the years and includes the Commercial DD aspect which may have been overlooked previously. From your experience are you finding that you are able to carry out your own DD better than using a consultant and that the appointment of a consultancy firm is often largely driven by the need to “cover ones self” in the event of a poor judgement to proceed with the deal? In other words, i often find that practitioners in a given industry, are most effective at identifying risks, opportunities and arriving at a suitable valuation. Is this trend shared amongst you in other parts of the world?
