Question
An IS auditor has been asked to perform a post-implementation review of a newly developed system. When reviewing the testing phase results, the auditor observed that separate modules of the system tested correctly in the user acceptance testing (UAT) phase, but some features did not work as expected when moved to production. Which of the following was MOST likely omitted prior to implementation?

Explanation
The most likely omission is integration testing. While separate modules may have passed in isolation during user acceptance testing (UAT), integration testing ensures that the system functions correctly when different modules and components interact with each other in a production environment. The absence of integration testing could lead to issues when features don't work as expected in production.
