Incorrect Answers:
A: Detective controls simply detect and report on the occurrence of problems. They identify specific symptoms to potential problems.
C: Corrective actions are steps to bring the future performance of the project work in line with the project management plan. These controls make effort to reduce the impact of a threat from problems discovered by detective controls. They first identify the cause of the problems, then take corrective measures and modify the systems to minimize the future occurrences of the problem. Hence an incident should take place before corrective controls come in action.
D: Scope creep refers to small undocumented changes to the project scope.
