# Role of IS Auditor in SDLC

The system development life cycle is the process of creating and implementing a new system or software. **The IT auditor's role is to ensure that the system development process is effective and that proper controls are embedded in the system.**

Here's a breakdown:

1. **Reporting to senior management**: The IT auditor **independently reports to senior management** about the system development process. They provide updates and information to ensure that the process is on track.
2. **Embedding controls**: The IT **auditor ensures that important controls**, such as audit trails for financial transactions, **are embedded in the system development process**. This helps to reduce risks and make the system more effective.

The IT auditor is involved in different phases of the system development life cycle:

1. **Feasibility study**: The IT auditor can **provide advice** on whether developing a new system is the best solution and **whether it should be done in-house or outsourced**.
2. **Requirement phase**: The IT auditor **ensures that user input is properly gathere**d and communicated to the development team. They also consult with senior management to ensure everyone is satisfied with the requirements.
3. **Design phase**: The IT auditor **reviews the system development methodologies** used by the team and provides advice on their appropriateness. They also ensure that guidelines and procedures are followed for outsourcing.
4. **Development phase**: The IT auditor focuses on **testing, ensuring that a proper test plan is in place and that errors are resolved**. They also review user acceptance test results.
5. **Implementation phase**: The IT auditor **provides recommendations on system changeover methodologies**, considering risks and costs.
6. **Post-implementation phase**: The IT auditor **conducts a review to assess** whether the system has **achieved its objectives and whether users are satisfied**.

Overall, the IT auditor's involvement in the system development process helps to ensure that controls are embedded and risks are reduced, leading to a more effective and reliable system.
