Event Density Anomaly Detector

Most weeks, the total volume of events across the portfolio fluctuates within a predictable range. When a week's total activity significantly exceeds that range — beyond the statistical control limits — it indicates that something unusual happened across the entire portfolio simultaneously. That could be a major deployment, a regulatory deadline, or a crisis — but it needs to be understood.

What you can conclude

• A week flagged as an anomaly requires explanation — what happened that drove unusually high activity across all projects simultaneously?
• Consecutive anomaly weeks indicate sustained systemic stress — the organization is operating outside its normal capacity range.
• A portfolio that stays within control limits consistently is predictable and stable — no systemic concerns.
