Introduction: 

The auditee is a manufacturing company that produces goods for the retail industry. The company has a hierarchical organizational structure and has implemented an ERP system to manage its production operations. The company has a business continuity plan that covers all the essential elements required to maintain its operations in the event of a disruption. The audit firm, ABC Auditors, is a well-known auditing firm with expertise in auditing manufacturing systems. The team comprises of three auditors with the necessary skill sets and experience to conduct this audit. John Doe, a Certified Information Systems Auditor (CISA) with ten years of experience in the field, is the team leader.

Auditee Environment: 

The auditee is a manufacturing company that produces goods for the retail industry. The company has a hierarchical organizational structure and has implemented an ERP system to manage its production operations. The technology infrastructure comprises of servers, desktops, laptops, printers, and other peripherals. The company’s business continuity plan covers all the essential elements required to maintain its operations in the event of a disruption. The plan includes details of critical business functions, key personnel, recovery strategies, communication plans, and testing procedures. The auditee’s internal policies and procedures include an information security policy, a disaster recovery policy, and an incident response policy. The regulatory requirements include the Payment Card Industry Data Security Standard (PCI-DSS) and the General Data Protection Regulation (GDPR).

Background: 

The manufacturing company’s management team has realized the importance of having a robust business continuity plan in place to ensure that the business can continue its operations in the event of a disruption. The company’s production operations are critical to its success, and any disruption can result in significant financial losses. The management team has engaged ABC Auditors to audit the business continuity plan and ensure that it is comprehensive, effective, and can provide the business with a roadmap for resuming normal operations in the event of an unexpected disruption.

Situation: 

The audit team has reviewed the current business continuity plan and identified areas for improvement. The auditee’s plan is not comprehensive enough to cover all possible scenarios that may arise, and some of the recovery strategies need to be updated. Additionally, the communication plan needs to be improved, and the testing procedures need to be more rigorous.

Terms and Scope of assignment:

The audit team will review the auditee’s business continuity plan to ensure that it is comprehensive, effective, and can provide the business with a roadmap for resuming normal operations in the event of an unexpected disruption. The audit team will focus on critical business functions, key personnel, recovery strategies, communication plans, and testing procedures.

Logistic arrangements required:

The audit team will require access to the auditee’s business continuity plan, system software, database, application software, and documentation. The audit team will use Computer-Assisted Audit Techniques (CAATs) to review the plan and identify areas for improvement.

Methodology and Strategy adapted for execution of assignment:

The audit team followed a structured methodology that was adapted from the Institute of Internal Auditors (IIA) and Information Systems Audit and Control Association (ISACA) guidelines, as well as industry best practices. The methodology included the following steps:

Planning:
