Meaning
Tail dropping is an ordinal valuation metric that registers the exact point where portfolio returns decouple from founder attention after a departure. The index operates on a descending gradient scale, tracking the continuous dilution of legacy oversight against incoming operational variance. Boundary conditions apply strictly to post-founder transition phases, ceasing to function once a successor achieves full structural autonomy.
Cost Gradient
Post-founder oversight decline generates an invisible operational friction that consumes human capacity rather than financial capital. The downward slope steepens when remaining teams attempt to interpret missing signals without historical context. Each abandoned administrative routine creates a proportional deficit in institutional memory, requiring double the attention hours from whoever inherits the fragmented domain.
Attention Delta
Measuring the gap between original strategic intent and current execution reveals the velocity of organizational drift. This differential signal exposes where informal communication channels fail after the departure of the primary architect. Calibration of the delta relies on comparing historical decision speeds against the sluggish output of newly formed committees.
Yield Decay
Residual asset productivity follows a predictable curve downward once the initial momentum of the founding era ends. Without constant re-injection of the original creator focus, process efficiency degrades into routine compliance. The resulting output reduction demonstrates that long-term enterprise value depends entirely on continuous oversight rather than static infrastructure.
