In most companies (unless the company is rich enough to pay for external Internal auditors) people who are not interested in doing audits are assigned the job ( read forced upon them)
, this is one major cause of shoddy internal audits , primarily because the auditors are disinterested & demotivated.
I always believe the organization should ask for volunteers , and once you find the volunteers they need to be trained in appropriate skills and given experience & exposure ( latter might come by shadowing experienced auditors)
