 The most important thing for an IS auditor to determine during the detailed design phase of a system development project is that acceptance test criteria have been developed. Acceptance test criteria define the expected functionality, performance and quality of the system, and are used to verify that the system meets the user requirements and specifications. The IS auditor should ensure that the acceptance test criteria are clear, measurable and agreed upon by all stakeholders. Program coding standards have been followed is something that the IS auditor should check during the coding or testing phase, not the detailed design phase. Data conversion procedures have been established or the design has been approved by senior management are things that the IS auditor should verify during the implementation phase, not the detailed design phase. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 323
