| current alternative | A feasible Method, variant, support change, status quo, stop, or next-slot course available to the named decision within its window. | A historical example or impossible ideal is not a current alternative unless it changes the decision. |
| domain result | The result in the receiving practice that the Method-related Work is intended to help produce or protect. | A Method task pass, conformance result, or positive report is not automatically the domain result. |
| burden | Time, cognitive, coordination, resource, maintenance, transition, or evidence burden observed or credibly estimated for the alternative. | Burden is not one scalar unless an explicitly defined aggregation is justified for the decision. |
| capability demand | The holder, Work family or result class, operating envelope, measures, qualification window, and evidence required for reliance. | Training completion, title, assignment, permission, authority, or one success does not establish capability. |
| side effect | A result outside the primary intended result that may help or harm the decision. | An unobserved possibility remains a risk or gap, not an effect. |
| opportunity cost | The named alternative Work, investment, learning, evidence, or receiving result displaced by the choice. | “Cost” without the forgone course is not yet an opportunity-cost claim. |
| reversibility | The conditions, time, information, and retained alternatives needed to undo or branch the choice. | A reversible tool setting does not make changed Method semantics, lost evidence, or organizational commitment reversible. |
| evidence strength | The qualified reach of observations, reports, comparisons, contribution or causal claims for this cell and window. | It is not a confidence adjective detached from source, use, and missing basis. |
| practical-worth decision | A bounded keep, revise, replace, branch, or stop result with reasons, unresolved trade-offs, and what that action preserves, creates, or changes. | It transfers neither as universal Method rank nor as authority to implement the decision. |
