The greatest concern for an IS auditor would be the lack of documentation for the basic assumptions and formulas used to develop the AI system's decision logic. This absence can lead to issues with transparency, accountability, and the ability to audit or validate the system's outputs. Proper documentation is critical for ensuring that the system operates as intended and that its decisions can be explained and justified if questioned.
