Revenue management — the four preconditions that generalise yield management beyond airlines

Claim. RM as a discipline depends on four preconditions: (1) a fixed, perishable resource; (2) a time-limited window of sale; (3) heterogeneous willingness-to-pay across buyers; (4) controllable segmentation (the ability to fence segments apart so price differences hold). Where all four hold, RM-style pricing-by-segment + capacity allocation generates measurable lift.

Confidence. Industry-consensus. Restated repeatedly across OR textbooks and industry-practice sources; not a single-citation claim.

Caveats. Pure-services SMBs often have only partial preconditions (e.g., calendar slots are perishable, but segmentation is harder); residential trades typically have low controllable segmentation. The framework helps decide whether an RM-style edge is even available before investing in price intelligence.

Implication / use. Use as the screening test in any pricing-edge argument. Before quoting AA's $1.4B, ask whether the SMB context has all four preconditions — if not, the analogy is honest only as direction, not magnitude.
