The best way to reduce the stress of an IT audit is to incorporate audit planning into the IT team’s ongoing strategic planning activities. That means that you shouldn’t wait for an audit to be announced before you start to prepare for it.
An audit coordinator and a backup coordinator should be named for each team or department, and they should work together to develop an audit-planning document that can be distributed to stakeholders regularly. Coordinators should be responsible for audit preparations and planning on an ongoing basis.
That said, the audit preparation process is doomed to fail without open communication about changes to the IT landscape. With that requirement in mind, it is crucial to include audit coordinators in the change management process for their area.
