Which of the following practices is MOST helpful in preventing incidents as a result of implemented software changes?

Question

Options

• APersonnel obtain senior management approval prior to implementing changes.
• BStandardized procedures are used for prompt handling of changes.
• CProposed changes are tested by stakeholders prior to implementation.
• DEvidence of successful changes are documented.

• A
  3% (1)
• B
  3% (1)
• C
  86% (30)
• D
  9% (3)

Explanation

Testing proposed changes with stakeholders before implementation directly addresses the root cause of change-related incidents - undetected defects, integration failures, or unintended side effects - by validating behavior in a controlled environment before it can affect production. A is incorrect because management approval is a governance control that authorizes changes but does nothing to verify the change will work correctly. B is incorrect because standardized procedures improve consistency and speed of handling changes, but a well-documented bad change still causes incidents. D is incorrect because documenting successful changes captures historical evidence after the fact - it informs future decisions but does not prevent current incidents.

Memory tip: Think "prevent before, not manage after" - only testing (C) occurs before the change goes live, making it the only option that can actually stop a problem from reaching production.
