| - | An Authoritative Source of Truth (ASoT) architecture provides the framework to ensure the validity and truthfulness of digital artifacts as they are managed throughout their lifecycle and the integrity of the enabling technological systems. According to a presentation by participants of an Air Force Study [4], the ASoT architecture owners should organize it according to technical platforms or domains and not by specific programs. The platform or domain focus of the ASoT architecture maximizes the usability of the digital artifacts by the communities of practicing engineers [4]. A governing entity that determines Systems of Record (SoRs) does so on the basis of digital artifacts used in its domain. For example, SoRs may include a requirements database, engineering cost data, a model-based systems engineering (MBSE) environment, and computer aided design (CAD) systems for transport aircraft. In order to satisfy the conditions for authority, the ASoT architecture must maintain the integrity of these technological systems in order to ensure that one – and only – one SoR exists for each digital artifact. As such, there is a one-to-many relationship between an ASoT and many digital artifacts. | + | An Authoritative Source of Truth (ASoT) architecture provides the framework to ensure the validity and truthfulness of digital artifacts as they are managed throughout their lifecycle and the integrity of the enabling technological systems.
