ISO 19650 part 4 provides detailed process and criteria for the decision points in the process of executing an information exchange within information management as defined by ISO 19650. It promotes a sustainable approach to information exchange where the immediate delivery of information does not preclude its future use.
It is applicable to any information exchange within project stages (ISO 19650 part 2) and within in-use events (ISO 19650 part 3). All development and information exchanges should be executed under the appropriate security controls (ISO 19650 part 5). It supports the satisfaction of a specific EIR/AIR related to an individual information exchange of any type of information by enumerating criteria relating to completeness, compliance to formal exchange schemas, the continuity of concepts between exchanges and the elimination of spatial and specification conflicts.
