What does anti-signal indicate in KPI Signals?

In the context of KPI Signals, anti-signal indicates a scenario where there is no detectable signal or trend in the data being monitored. It signifies that the performance metrics are stable enough that they do not trigger any alerts or indicate a shift in the expected outcomes. This situation is characterized by a lack of significant fluctuations, meaning that any expected changes in performance are either absent or minimal, hence no actionable signal is generated.

The other options, while related to data interpretation, do not accurately describe the concept of anti-signal. Long-term stability relates to consistent performance over an extended period, which may not necessarily mean that a signal is absent. Abnormal variation in KPI scores indicates fluctuations or deviations from expected performance, which directly contradicts the idea of an anti-signal. Lastly, changes in workflows may lead to variations in KPI signals, but this does not align with the definition of anti-signal, which is specifically focused on the lack of any signal at all.
