Which of the following is NOT a risk associated with automation systems?

In the context of automation systems, increased efficiency is not a risk but rather a primary benefit of implementing automation technologies. Automation systems are designed to perform tasks with greater speed, consistency, and precision than human operators, which often leads to enhanced productivity and output quality. This efficiency gain can also reduce operational costs and free up human resources for more complex decision-making tasks.

On the other hand, system failures, cyber security threats, and potential safety hazards are indeed risks associated with automation systems. System failures can occur due to various reasons, such as software bugs, hardware malfunctions, or improper maintenance. Cyber security threats pose significant risks, as automated systems often rely on network connectivity, making them vulnerable to attacks. Potential safety hazards can arise from automation, especially in settings where machines interact with human workers, creating the need for stringent safety protocols and risk assessments. Thus, while the other options represent genuine concerns in the realm of automation technology, increased efficiency stands out as a positive outcome and is not considered a risk.
