Every hybrid model works at half load. The question is what it does at peak, when the exception queue grows faster than the people who clear it.
Design for the bad quarter
Model your staffing against the worst eight weeks you had last year, not the average. Averages hide precisely the period where the model has to earn its keep.
Three traits that hold
An explicit escalation threshold that does not require a meeting. A named owner for the exception queue. And a degradation path — what the system does when it cannot keep up — chosen in advance rather than improvised.
Every hybrid model works at half load.
Rehearse the failure
Run one deliberate overload drill a quarter. Teams that have never seen their model saturate will discover its limits at the least convenient moment.
