What does impact analysis involve?

• A. Investigating the cause of a failure
• B. Determining risks before implementation
• C. Assessing how changes affect system components
• D. Calculating costs of system alterations

Answer: (C)

Impact analysis specifically pertains to understanding how changes within a system will affect its components, functionality, and overall performance. In functional safety, it becomes particularly important to evaluate not just the direct consequences of changes, but also any indirect effects that those changes may have on the system's safety and compliance with required safety standards. This process involves a systematic examination of how alterations in one area of the system might propagate through to others. For instance, if a new feature is added or a component is replaced, it is essential to assess how this could influence safety mechanisms, system interactions, and overall risk profile. This is crucial in ensuring that any changes do not inadvertently introduce new hazards or compromise existing safety measures. In contrast, the other options focus on different aspects of system management. Investigating the cause of a failure pertains to root cause analysis, which seeks to identify why a specific failure occurred rather than how changes will affect the overall system. Determining risks before implementation relates to risk assessment practices, which analyze potential risks associated with a planned change rather than the impacts themselves. Calculating costs of system alterations is more aligned with budget considerations and project management than with the safety implications of those alterations. Therefore, impact analysis is distinctly focused on the assessment of changes and their effects on
