Fumiko is managing a project to develop a new software system for airline scheduling. The team has been notified that the quality department plans to do an audit of the project next week. The team objects to the audit because they feel they don't have time for it with all the pressure they are already feeling to get the project finished as soon as possible. What should Fumiko explain to the team so that they will understand the purpose of the quality audit?

$$ the audit will identify inefficient and ineffective policies

the audit will check if the customer is following its quality process

the audit is part of an ISO $9000$ investigation

the audit will check the accuracy of costs submitted by the team
