Section 11 of 103
10. Definition, Requirement, Rule and Statement
Stable section ID: S05-CON-015-SECTION-11 · 5 content blocks
A Definition establishes the controlled meaning of a term or concept within a declared scope. A definition supports interpretation but does not automatically prescribe a design action.
A Requirement is a uniquely identifiable, traceable, and verifiable obligation defining what shall be achieved, prevented, provided, documented, or demonstrated.
A Rule is an authoritative provision governing interpretation, decision-making, design, behavior, process, compatibility, or lifecycle management. A rule may generate one or more requirements but may also govern matters that are not evaluated as individual product requirements.
A Statement is any formally expressed proposition within a System05 document. A statement may be normative or informative and shall not be assumed to have a particular authority merely because it is labeled a statement.
Documents shall preserve these distinctions. Definitions shall not conceal requirements, informative statements shall not be treated as rules, and broad rules shall be translated into traceable requirements where implementation or verification demands greater specificity.
