What type of error results in detrimental outcomes for property, personnel, or mission objectives?

The correct answer is consequential error. This type of error specifically refers to mistakes that lead to negative or harmful outcomes affecting property, personnel, or mission objectives. It emphasizes the impact of the error rather than the error itself. Recognizing consequential errors is vital in operational risk management because it underscores the need for effective strategies to identify, mitigate, and prevent such errors from occurring in the first place. By understanding these errors, teams can implement better training, processes, and risk assessments to ensure mission success and the safety of individuals involved.

Other error types, while they can also contribute to negative situations, do not specifically highlight the resultant harm as consequential errors do. Human errors may lead to various outcomes but aren't intrinsically linked to negative consequences. Procedural errors refer to mistakes made while following procedures, and while they can have consequences, they do not inherently denote that a detrimental outcome will occur. Operational errors typically describe missteps in executing tasks or missions but again lack the direct emphasis on the negative outcomes associated with them as consequential errors do.
