 +
 +===== Discussion =====
 +
 +A Constraint establishes a boundary within which an entity exists, operates, or participates in a system. It restricts one or more characteristics, values, relationships, configurations, behaviors, or operating conditions.
 +
 +A requirement states an obligation. A Constraint restricts the acceptable ways in which an entity satisfies an obligation. A requirement may establish, apply, or govern one or more Constraints.
 +
 +Constraints associated with a [[public:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]] include environmental, security, deployment, communication, resource, timing, and configuration restrictions.
 +
 +===== Definition =====
 +
 +*condition that restricts the permitted characteristics, values, relationships, configurations, behaviors, or operating circumstances of an entity*
 +
 +===== Source =====

 +Dido Solutions, Inc. and Jackrabbit Consulting, Inc. Project definition.
 +
 +===== Note =====
 +
 +A Constraint does not necessarily constitute an independent requirement. A requirement establishes an obligation when it requires a system or responsible entity to impose, enforce, validate, or comply with the Constraint.
 +
 +A Constraint should identify:
 +
 +  * The entity subject to the restriction
 +  * The restricted characteristic, value, relationship, configuration, behavior, or operating circumstance
 +  * The permitted boundary or condition
 +  * The circumstances under which the restriction applies
 +  * The source or authority establishing the restriction
 +
 +===== Example =====
 +
 +A Test Environment description specifies that every participating Node uses an approved communication protocol. The protocol restriction constitutes a Constraint. The requirement directing DIDO-TE to record and enforce the restriction establishes the corresponding obligation.
