You are a project manager for a major information system project when someone from the quality department comes to see you about beginning a quality audit of your project as soon as possible, you object to the audit. You should explain to the team that the purpose of a quality audit is:

  

Part of ISO $9000$ investigation.

To check the accuracy of costs submitted by the team.

To check if the customer is following its quality process.

To identify inefficient and ineffective policies.
