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.
Unpredictable delivery: frequent missed commitments, shifting deadlines, unreliable follow-through.
High predictability: realistic commitments and stable delivery cadence.
Reliable in low-load contexts, but degrades under overload or competing commitments.
Measure
• Accuracy: fidelity of promised scope/timing vs actual delivery.
