What this shows

A classic go/no-go framed as an influence diagram, written with the inline mode: influence directive (the alternative to the decisiontree:influence header). The decision-maker controls one rectangle — whether to enter — against two uncertain ovals, market demand and the competitor's response, all feeding a single profit octagon.

Two arcs land on the decision and the value node from demand. Demand -> Enter is a dashed informational arc: demand is read before committing to entry, so the choice can react to it. Demand -> V and Competition -> V are functional arcs — both directly shape profit — while Enter -> V ties the chosen action into the payoff. The graph stays acyclic and carries exactly one value node, the two structural rules the engine enforces; it captures the shape of the bet without unrolling every demand-by-competitor branch into a tree.
