Scenario Arc Coherence

Scenario arc coherence is the structural quality that distinguishes an integrated multi-move scenario from a concatenation of disconnected moments. A coherent arc has phases that shape each other causally — the opening determines what is possible in the middle, the middle produces the conditions the close responds to, the complication is structurally embedded rather than surprise-dropped. Arc coherence is the load-bearing element of Scenario Enactment; incoherent arcs produce enactments that practice sequential moments rather than integrated situations. The concept extends beyond Scenario Enactment to any activity that uses multi-move material, including some Action Learning Set activities and multi-session Project-Based Learning scenarios.
