Definition
Poles
Each HES element is a spectrum, not a category: the Low and High poles describe how it presents at its two extremes, while the Reference marks the typical, everyday middle. The poles map variation across the range — neither end is inherently better or worse.
Brittle plans: a single disruption collapses execution; minimal buffering and no realistic contingencies.
Robust plans: expected disruptions are anticipated; buffers and decision branches preserve progress.
Adds buffers after painful lessons, but coverage is inconsistent and not systematic.
Measure
• Robustness: degree to which plan outcomes hold under typical disruption scenarios.
