   An organization is implementing a new inventory management system. The project manager proposes to skip system testing and move directly from unit testing to user acceptance testing to save time. The IS auditor should advise against this because:

   • AUnit testing is sufficient to ensure the system works correctly as a whole.
   • BSystem testing validates that the integrated system meets functional and technical requirements before business users test it.
   • CUser acceptance testing can uncover all technical defects, so system testing is redundant.
   • DSkipping system testing will reduce the overall project cost and risk.

   A hospital is implementing a new electronic health record (EHR) system. The project manager schedules a two-week user acceptance testing (UAT) phase with a small group of power users. The UAT script includes only happy-path scenarios. During UAT, the power users report that the system is 'good enough' and sign off. The go-live is approved. What is the most significant risk in this approach?

   • AThe UAT script should have included only negative test cases to uncover defects.
   • BUAT should have been performed by the IT team, not end users, to ensure technical correctness.
   • CThe power users were not given enough time to learn the system, so their sign-off is not valid.
   • DUAT did not include a representative sample of end users or realistic workflow variations, so the system may fail in routine use.
