In agreement with the post above that it is more beneficial to be proactive than reactive. In the reactive approach, a root cause analysis is usually performed to answer ‘why’ a problem exists. However, with the proactive approach, different kinds of corrective actions will prevent the ‘why’ from happening again. We are usually more likely to address known problems rather than investing resources to prevent problems from happening in the first place. There definitely need to be systems installed to assess and identify issues before they become problems.
