Integrating IBM DOORS (including DOORS Next Generation) and Aras Innovator using OpsHub Integration Manager involves connecting both systems via their APIs, selecting which DOORS modules and Aras ItemTypes belong in scope, mapping fields and relationships across both schemas, and starting the sync. OIM runs as a standalone application outside both systems no plugins installed in DOORS or Aras. The visual interface handles field mapping, attribute value translation, criteria-based filtering, and sync direction configuration. This integration is particularly relevant for defense, aerospace, and automotive organizations running requirements management in DOORS alongside PLM in Aras, where traceability between requirements and design items must be maintained without manual updates.
