A significant responsibility of an IS auditor when auditing software applications is to ensure that proper documentation is maintained. Documentation is crucial in the auditing process as it provides evidence of compliance with policies, procedures, and regulations. It helps auditors assess whether the software applications have been developed and operated according to established standards and best practices.

Proper documentation includes user requirements, design specifications, testing results, and maintenance records, all of which are essential for evaluating the adequacy and effectiveness of the software's controls. Additionally, well-maintained documentation facilitates a clearer understanding of the system's architecture and functionality, enabling the auditor to identify risks and suggest areas for improvement. In the context of auditing, the lack of appropriate documentation can lead to misunderstandings about the software's capability, security vulnerabilities, or compliance issues.

The other options, while important in other contexts, do not align with the core responsibilities of an IS auditor focused on ensuring software applications are properly managed and controlled. The auditor's role is not to further develop software, manage teams, or directly reduce costs, but rather to provide an independent evaluation of the software's compliance and risks through thorough documentation review.
