Auditing [predicated on the indirect assessment model] is easy because it is 20/20 hindsight all the time. Everybody else has done the work and all you do is come along and criticize. It is easy to be an art critic, but it is hard to paint. And an auditor is an art critic by definition, since accounting is an art form. Auditors are critics. So that is a lot easier than the doing. The management is doing the doing, if you like, selecting the measures. We are coming along and critiquing them so we are not stressed in terms of needing to understand [for example] the Department of Transportation systems. (Office auditor, January 1998)
