将需求细化为规范取决于需求“满足”的概念。这是一个递归过程，其中较低级别要求的满足被视为满足较高级别声明的充分条件[1]。可追溯性结构记录了不同抽象级别的需求之间的满意度关系。对于跨系统系列成功重用需求至关重要，它们包含有关系列中早期产品的需求之间的关系和上下文的足够信息，以向开发人员保证这些需求对于后续项目是有效的。不遵守这一原则可能会导致过晚发现错误或无法实现的需求，从而造成高昂的成本。
Refinement of requirements into specifications depends on the concept of requirements ‘satisfaction’. This is a recursive process, in which the fulfillment of lower-level requirements is seen as a sufficient condition for the fulfillment of the higher-level statement [1]. Traceability structures record satisfaction relationships between requirements at various levels of abstraction. It is essential for the successful reuse of requirements across system families that they contain sufficient information about the relationships between and context of requirements from early products in the family to assure developers that the requirements are valid for subsequent projects. Failure to observe this principle risks the late, and therefore costly, discovery of erroneous or unimplementable requirements.
