Which type of metrics provide evidence that something needs to be addressed?

The correct choice is intervention metrics, as they are specifically designed to signal when a situation or performance issue requires attention. These metrics act as indicators that highlight areas needing action, prompting managers and teams to investigate further and implement solutions.

Intervention metrics can include various data points such as response times, ticket escalations, or customer satisfaction scores that fall below acceptable thresholds. When these metrics indicate a decline in performance or service, it serves as a prompt for the organization to address the issue proactively.

In contrast, validation metrics are more focused on affirming the accuracy or appropriateness of a process or data. Direction metrics provide insight into progress toward goals or the trajectory of performance but do not necessarily indicate an immediate need for action. Justification metrics generally support decisions or actions taken rather than signal problems that need to be fixed. Thus, intervention metrics distinctly play a pivotal role in identifying when immediate corrective measures are necessary.
