What role does the Engineering Investigation (EI) serve?

The Engineering Investigation (EI) plays a critical role in identifying failures within technical or operational processes. This involves examining and analyzing incidents or issues that arise, determining the root causes of those failures, and proposing solutions to prevent recurrence. The primary goal of an EI is to enhance safety, reliability, and efficiency by ensuring that failures are thoroughly understood.

In contrast, the other choices refer to different aspects of oversight or management that do not align with the fundamental purpose of an Engineering Investigation. For instance, investigating economic impacts or managing contractor performance involves aspects of business management and oversight rather than the technical examination and troubleshooting inherent to an EI. Conducting routine equipment inspections is a proactive maintenance activity rather than an investigative process aimed at failures. Therefore, option B is the most accurate representation of the EI's role by focusing on the technical and operational failures that lead to improvements in processes and systems.
