Work Product: Architecture Viewpoint Definition (AVPD)

The Architecture Viewpoint Definition (AVPD) is a work product created when using the COMPASS Architectural Framework Framework (CAFF). The CAFF is a process based upon an earlier version of ISO 42010 that can be used to identify Stakeholders, Concerns, Terminology (Ontology Elements), and viewpoints for a conceptual model or system description. The key output of the work product is the identification and framing of viewpoints. This information is then used to create the Architecture Description Framework.

The creation of an Architecture Viewpoint Definition (AVPD) work product is carried out when creating the following:

  • System Description Architecture Description Framework using a conceptual model of an abstract system.

  • Architecture Description Framework for a system-of-interest using a System Description.

The Architecture Viewpoint Definition (AVPD) work product is included in the same location as the Architecture Description Framework.

COMPASS Architectural Framework Framework (CAFF)

The COMPASS Architectural Framework Framework (CAFF) provides the guidance for creating the Architecture Viewpoint Definition (AVPD). This guidance comes from the COMPASS Project. See the following website for further information:

The original materials used prior to the CAFF is from presentations at the Model Based System Engineering (MBSE) Festival INCOSEUK and papers presented at the 2014 Annual Systems Engineering Conference (ASEC) INCOSEUK conference.. This information is available from Simon Perry or in the book called "SysML for Systems Engineering, 2nd Edition: A Model-Based Approach".
