Which is the best approach for reducing incidents involving human error?

1. Increase worker hours

2. Improve system design

3. Reinforce strict disciplinary actions

4. Implement random checks

The correct answer is: Improve system design

Improving system design is a highly effective approach for reducing incidents involving human error because it addresses the root causes of mistakes by making tasks easier, safer, and more intuitive for workers. When systems are well-designed, they take into account human limitations and behaviors, thus reducing the likelihood of errors. This could be achieved by simplifying processes, providing clear instructions, or integrating fail-safes and alerts that guide workers through tasks safely. By focusing on the system’s design, organizations can create an environment where human errors are less likely to occur, rather than relying solely on punitive measures or additional checks that do not fundamentally change the underlying processes. This proactive approach encourages a culture of safety and efficiency, ultimately leading to a significant reduction in incidents related to human error.
