C.39.RQ:0 - Use This When

Use this pattern when a Method, an established-family or project-local grouping choice, or a proposed Method/Work/support structure may fail in the project’s situation. Enter when the practical question concerns the receiving result, performer capabilities, technical or organizational conditions, variability, evidence, authority, or acceptable burden and those conditions are not yet explicit enough for individual qualification or architecture comparison.

Begin with the situation family, intended or current Work, receiving professional result, and the level of the Method decision. State the contributions that a Method or several Methods must make without preselecting which candidate supplies them. Place every resulting criterion with the Method, description, performer capability, covering Work assignment, permission relation, decision-authority relation, performed Work, decision result, support/access relation, responsibility, cultural subject, or receiving result it actually concerns.

The first useful result is a bounded set of criteria with subjects, allowed variation, evidence needs, satisfaction observations, and stops. A criterion can be ready for later use even when no candidate currently meets it. Enter also when the present question concerns the justification of a criterion itself. That use can finish with a supported requirement recommendation and the criterion’s current force or amendment limit, without selecting a Method.

Do not use this pattern as a generic product-requirements template. Criteria do not identify, admit, select, qualify, or compose a Method or establish present or future fit. Product acceptance, Method identity, individual qualification, and architecture choice remain separate results.

C.39.RQ:0.1 - Working Distinctions

Name used here	Meaning
situation family	The recurring class of receiving Work and conditions for which criteria are intended, with important variation and exclusions explicit.
receiving Work and result	The dated Work occurrence or intended occurrence and the professional result it must produce or preserve. They are not the Method.
required Method contribution	A reusable action, result, or preserved condition needed from one Method or from named Method relations, stated before assigning it to a candidate.
criterion subject	The actual object or relation constrained by a criterion: Method/account content, MethodDescription, performer capability, covering Work assignment, permission relation, decision-authority relation, performed Work, decision result, support/access, responsibility, cultural relation, or another domain subject.
performer capability	An ability needed to enact or judge a contribution. It is distinct from responsibility, access, assignment, permission, and decision authority.
Work assignment	A named assignment occurrence whose holder is one admitted System and whose scope and window cover specified Work. The assignment alone establishes neither permission, decision authority, performed Work, nor a decision result.
permission relation	An independently supported relation permitting a named System to perform a specified act within a stated subject, scope, window, and basis. It does not create an assignment, prove performance, or confer decision authority beyond that exact permission.
decision-authority relation	An independently supported direct relation under which a named System may issue a named decision result. Its subject, decision scope, window, basis, and evidence for reliance are explicit; assignment, performed Work, capability, responsibility, access, and acceptance need separate evidence.
allowable variation	A range or branch that may change while the receiving result and non-negotiable conditions remain protected.
burden limit	A bound on time, attention, capacity, delay, coordination, cost, or another named burden at its actual participant, scope, and window.
evidence need	The observation or record required before a later decision may rely on criterion satisfaction. It is not satisfaction by itself.
acceptance or stop observation	The observable condition under which the criterion can be passed to a later decision or must stop that route. It does not accept a Method or product by itself.
