Plus/Minus Boundary Review¶
Review ritual — instantiates Objective Boundary Governance
A recurring ritual that admits a new objective only when a matching one is retired or parked, keeping addition and subtraction friction symmetric.
The Plus/Minus Boundary Review is a recurring ritual built on a single hard rule: nothing enters the objective set without something leaving it — retired or parked. Its defining trait is that it forces a paired subtraction. Where a change board can admit an addition on its own merits and an opportunity-cost review merely prices what an addition displaces, this ritual makes the swap physical: the boundary structurally cannot ratchet outward, because every "plus" must be matched by a "minus." It attacks objective creep at its mechanical root — the asymmetry between an easy addition path and a hard removal path — by welding them together into one move.
Example¶
A regulatory agency governs a growing stock of rules, and every year it accretes more, because adding a rule solves a visible problem while removing one just invites a fight. The agency adopts a plus/minus boundary review modeled on a "one-in, one-out" discipline: any new rule proposed in a cycle must arrive paired with an existing rule of comparable burden to repeal or sunset, and the review keeps a running "+/–" ledger for the cycle that must net to zero.
A team proposes a new disclosure requirement. Under the ritual they cannot simply add it; they must nominate an obsolete filing rule to retire in exchange, or park the new requirement until a matching removal is found. The disclosure is genuinely useful — but so was the last twenty additions, and that is exactly the point. The ritual doesn't judge merit; it caps the stock, so the regulatory burden stops ratcheting and the agency is forced to decide what it values most, not merely what is good.
How it works¶
- Recurring cadence — the review runs on a fixed cycle, so the plus/minus discipline is a habit, not a one-off.
- Each plus is paired with a minus — an addition is admitted only alongside a retirement or a parking of a comparable objective.
- Comparable burden, not just count — the "minus" must match the "plus" in weight, or the ritual is gamed by trading a trivial removal for a major addition.
- Symmetric friction is the whole point — subtraction is made exactly as routine as addition, breaking the ratchet.
- Unmatched additions are parked — a genuinely good idea with no available swap goes to the parking lot rather than bloating the boundary.
Tuning parameters¶
- Swap ratio — 1:1, or a stricter 2:1 to actively shrink the objective set. Higher ratios cut harder but can starve legitimate growth.
- Comparability basis — matching by count (easy to game) vs. by burden or cost (harder, fairer).
- Strictness — a hard rule (no swap, no entry) vs. a guideline the board can override. Hard rules bite but can block the genuinely necessary.
- Cadence — frequent reviews keep pressure steady; rare ones let a queue of unmatched pluses build.
- Parking-lot valve size — how much can be deferred rather than swapped, which relieves pressure but can become a loophole.
When it helps, and when it misleads¶
Its strength is structural: it prevents the ratchet by construction rather than by vigilance, and it forces the prioritization that a permissive "just add it" culture avoids. When additions are individually reasonable, capping the stock is often the only honest way to keep the objective coherent.
Its failure mode is gaming the swap — retiring a token rule to admit a major one, defeating the discipline while satisfying its letter — which is the well-documented weakness of real one-in-one-out[n1] regimes when burden isn't measured. A hard cap can also block a genuinely needed addition when no swap is available, tempting the anti-learning failure the archetype warns of. The guarding discipline is to match on burden rather than count, keep a sanctioned parking lot as an escape valve for the necessary-but-unmatched, and reserve an explicit emergency exception for safety and legal additions that must not wait for a trade.
How it implements the components¶
friction_symmetry_check— the ritual's core act: making subtraction exactly as routine and required as addition.removal_and_sunset_path— each admitted addition triggers an actual retirement or sunset of a matched objective, not just a promise to remove it someday.deferred_objective_parking_lot— additions that can't yet be matched with a removal are parked rather than admitted.
It does not implement opportunity_cost_register (the Opportunity-Cost Review), objective_boundary_ledger (the Sub-objective Decision Record), or sub_objective_admission_rule (the Objective Change-Control Board). This review enforces an actual one-out swap; the opportunity-cost review only prices what an addition would displace.

Editorial Notes¶
Form Classification¶
Form family: Decision, Gate & Allocation
Rationale: Plus/Minus Boundary Review operates as a case-specific gate, selection, routing, prioritization, or resource disposition because it a recurring ritual that admits a new objective only when a matching one is retired or parked, keeping addition and subtraction friction symmetric.
Independent corroboration: The frozen evidence defines Plus/Minus Boundary Review as 'A recurring ritual that admits a new objective only when a matching one is retired or parked, keeping addition and subtraction friction symmetric', so its operative form is Decision, Gate & Allocation.
Review outcome: Independent reviewer agreement; high confidence.
Origin Attribution¶
Primary origin: Public Administration & Policy
Origin pattern: Cross-disciplinary synthesis
Present-day reach: Multi-domain
Rationale: Plus/Minus Boundary Review is rooted in public administration and policy: Regulatory budgeting's one-in-one-out rule formalized symmetric addition and retirement constraints.
Related originating lineages:
- Law & Governance — Law and governance materially shaped Plus/Minus Boundary Review through rights, duties, due process, contracts, and institutional rules.
- Operations Research — Capacity constraints and constrained portfolio optimization supply the add-one-remove-one logic.
- Organizational & Management Science — Organizational and management science materially shaped Plus/Minus Boundary Review through coordination, organizational learning, performance, and change practice. Portfolio review that admits new objectives only through explicit tradeoff is an organizational priority-governance practice.
Review resolution: Light authoritative-source research resolves the primary-origin disagreement in favor of public administration and policy. OECD: One-In, One-Out and Regulatory Budgeting directly documents the defining practice or theory described in the selected origin rationale. Other listed domains are retained only where the blind reviews identify material co-development or translation; broader adoption remains separate as domain_reach=multi_domain.
Attribution caveat: The boundary with organizational and management practice is real because that field materially developed or translated the practice, but the cited provenance places the defining form in public administration and policy.
Encyclopedia synthesis: The exact catalogued form synthesizes established practice rather than reproducing a single standard historical label.
Review outcome: Researched adjudication after independent review; high confidence.

Notes¶
[n1] One-in, one-out (and stricter variants like one-in-two-out) is a regulatory-budgeting rule requiring that each new rule's cost be offset by repealing existing rules of equivalent burden, adopted by several governments in the 2010s to cap the growth of regulatory stock. Its known weakness — trading away trivial rules to admit costly ones — is exactly why comparability must be measured by burden, not count. ↩
