A: A system model View («view») defines a projection on a Model from the perspective of a set of stakeholders (e.g., Customer, Systems Engineer, Test Engineer), where the perspective is of a set of stakeholders is defined as a Viewpoint («view»). In SysML both View and Viewpoint are first class elements than can be precisely defined. SysML defines a Viewpoint as a stereotype (customization) of Class with tagged values (properties) for stakeholders, concerns, languages, methods, and purpose. A Model View conforms to the perspective of its Viewpoint, as shown by a «conform» Dependency arrow.
For example, see the Views & Viewpoints figure below.
