Protiviti's report for its 2010 Internal Audit Capabilities and Needs Survey is out, and shows some interesting results as to where companies view themselves in terms of their internal audit knowledge.
I encourage you to look over the full report for an explanation of their methods and full scores, but I wanted to highlight a couple of points.
Respondents appeared to feel they last less technical knowledge than process knowledge. For example, in the general technical knowledge question, the top 5 responses were general assessment of IT (GAIT) risk, IFRS, XBRL, ISO 27000 (information security), and COBIT. On a scale of 1-5 in technical acumen, respondents rated themselves between 2.1 (XBRL) and 2.7 (COBIT). Not a lot of confidence there.
For processes, though, the answers were nearly a point higher on average: from auditing IT -- program development (3.1) to statistical analysis, data manipulation, and quality assurance and improvement (all 3.3).
