Escalation Score Timeline(3.6.5)

This is the longitudinal view of portfolio governance health. Rather than showing where things stand today, it shows how the composite risk score for each project has moved over time — whether projects are trending toward escalation, stabilizing after an intervention, or continuing to deteriorate.

For executives reviewing governance trends, this is the primary evidence of whether the organization's risk management is improving or getting worse over time.

What you can conclude

• A project whose score is rising consistently toward the 70-point escalation threshold needs intervention now — before it breaches the threshold.
• A project whose score dropped sharply after a specific week demonstrates that an intervention worked — useful evidence for governance reporting.
• A portfolio where all projects show declining scores over time is the target state — risk is being actively managed down.

How this chart works

Multi-line time series showing the composite risk escalation score per project per week. Threshold lines at 70 (escalation required) and 85 (board alert).

The score blends three measurements, each expressed as a percentage so that a large project and a small one are comparable: the share of the week's resolved issues that took longer than their target (weighted 35), the share of the week's status changes that were reopens (weighted 25), and the share of the week's issues that stalled rather than moved (weighted 20). An issue counts as stalled once it has sat in the same status longer than two and a half times the usual time for that status, and at least a day.

A week is only scored on the measurements it has enough activity to support: at least three resolved issues, five status changes, or three issues respectively. The score is the weighted average of whichever measurements qualify, so a quiet week is not penalized for the ones it cannot support. Where a week supports none of them the line is left blank rather than drawn at zero — a gap means too little happened to judge, never that risk was absent.
