Priority Supply Ladder

Prioritization policy — instantiates Sustainment-Reach Alignment

A ranked rule for who the line feeds first when it cannot feed every front — and what the fronts below the cut-line are chartered to do on their own.

When sustainment can't cover every front, someone decides who goes short — and if no one decides in advance, the loudest or nearest front wins, which is rarely the right one. Priority Supply Ladder fixes that ranking ahead of the shortfall: an ordered ladder of claims on the support line, rung by rung, plus a declared cut-line and a standing charter for what fronts below it must do without the line. Its defining move is that it rations a fixed, scarce delivered supply rather than trying to grow it — it presupposes the line is already short and answers only "who first, who waits, who self-sustains," so scarcity is met by policy instead of by panic. It allocates; it does not measure the shortfall or create more supply.

Example

A city hits a severe drought stage, and its treatment-and-distribution "line" can deliver only about 70% of normal demand. The Priority Supply Ladder is the ordinance written before the reservoirs ran low. Top rungs — hospitals, dialysis, firefighting reserves, drinking water — are served in full. Middle rungs — schools, food businesses — are served with conservation targets. Bottom rungs — lawn irrigation, car washing, ornamental fountains — are cut first, and by charter are told to self-supply (greywater, rain barrels, stored stock) or go without.

When the shortfall bites, the city doesn't relitigate each user; it reads the ladder. The cut lands where the ladder placed it in advance, and the fronts below the line already know they are on their own — the charter told them so before the crisis, not during it. The scarce water goes where it changes outcomes most, and the argument that would otherwise erupt at the worst possible moment has already been had.

How it works

  • Rank before the shortfall. Order every claimant on the line by mission-criticality — not by volume, and not by volume of complaint — and write it down while things are calm.
  • Draw a moving cut-line. Pair the ladder with the delivered-supply figure so the cut-line rises and falls with how short the line actually is.
  • Charter the bottom rungs. Fronts below the line get an explicit autonomy floor: what they may do for themselves and what minimum they can still expect, so de-prioritization is not abandonment.
  • Serve top-down. Allocate to the highest rung first; only spill to lower rungs once the higher ones are met.

What distinguishes it is the pairing of pre-ranked triage with an autonomy charter for the cut-off — not any attempt to increase delivery, which belongs to other mechanisms.

Tuning parameters

  • Ranking basis — criticality vs. cost-to-serve vs. contractual priority. Which axis orders the ladder decides who eats the shortfall.
  • Cut-line rule — fixed rungs versus a proportional haircut across a band. Hard rungs are clear but brittle; proportional is fair but blurs accountability.
  • Autonomy floor — how much a de-prioritized front is guaranteed versus must self-source. A higher floor is humane but re-consumes the scarce supply.
  • Override / appeal path — whether a front can jump the ladder in a genuine emergency, and who approves. Too open and the ladder erodes; too closed and it can't handle real exceptions.
  • Reassessment trigger — what re-sorts the ladder as conditions change (a new front, a worsening shortfall).

When it helps, and when it misleads

Its strength is converting scarcity from a scramble into a rule, and — via the autonomy charter — telling the cut-off fronts in advance what they own, which is the difference between de-prioritization and betrayal. It is triage applied to a supply line: like medical triage, it accepts that treating everyone equally when you cannot treat everyone is itself a failure.[1]

A ladder is only as legitimate as its ranking; rank by the wrong axis — who shouts loudest, who sits nearest headquarters — and it hard-codes a bias into every future shortfall. The classic misuse is rank-shopping after the fact: reordering the ladder once you see who would be cut, to protect a favored front, which turns a fairness rule into a cover story. The discipline is to set and publish the ranking before the shortfall, log every override, and re-derive the ladder from stated criteria rather than from who complained.

How it implements the components

Priority Supply Ladder realizes the allocation-governance side of the archetype — the components a rationing policy can fill:

  • support_priority_policy — its core: the explicit, ranked order in which the line's scarce output is allocated across competing fronts.
  • front_autonomy_charter — the cut-line's underside: a standing declaration of what de-prioritized fronts may and must do for themselves, and the floor they can still count on.

It does not measure how short the line is (net_delivery_metric) — that is Net Supply Ratio Dashboard; and it does not procure alternative supply for the cut-off fronts (local_substitution_option) — that is Local Sourcing & Repair Protocol.

Notes

A ladder rations delivered supply; it does not repair the line. If shortfalls become chronic, a ladder can quietly become the way an organization lives with a broken line indefinitely instead of fixing its reach. Pair it with the burn-rate review and the rescope playbook so it stays a shock absorber, not a permanent condition.
