Every established discipline has a severity scale. Seismology has the Mercalli Intensity Scale. Meteorology has the Beaufort Scale. Nuclear safety has the International Nuclear and Radiological Event Scale. Each one works the same way: a numbered sequence where each level is defined not by measurement but by observable effects. You do not need a seismometer to tell the difference between crockery rattling and a building collapsing.

Programme management has no equivalent. We have RAG statuses — a three-point scale that tells you a programme is either fine, not fine, or on fire, with no gradation between them. We have earned value metrics that describe the mathematics of failure without capturing its texture. We have gateway reviews that produce recommendations no one reads until the programme is already at the level where the recommendations would have been useful.

The Cluster F**k Intensity Scale fills this gap. It is a ten-point classification system for programme disorder, defined entirely by observable effects. Each level describes what you would see if you walked onto the programme floor, sat in the review meeting, or read the weekly report with fresh eyes. No metrics required. No dashboards. Just pattern recognition.

Like the Beaufort Scale, the levels are defined by what moves. At Level 0, nothing moves. At Level 10, everything has moved and no one can explain where it went.
