OBD Requirements

Project Basics

Requirements are often stored in multiple systems engineering tools across businesses. This does not allow for requirements to be shared or allocated across the business. Teamcenter® Systems Engineering had been the tool of choice for storage and work management for On-Board Diagnostic (OBD) requirements, however in an effort to utilize a tool common across the business, OBD requirements and work management were migrated to PTC Integrity.




The data structure for TcSE and Integrity are quite different and there is not a way to directly move data from one system to the other. Additionally, Teamcenter ® Systems Engineering was set to be decommissioned, which added tight time constraints to the project. 


  • Created a data model and architecture for the OBD requirements schema in TcSE and worked with Integrity developers to recreate this within the Integrity tool.

  • Created a gap analysis report of new data structure.

  • Migrated all data and linkages from TcSE to Integrity. 10,000 requirements and 25,000 links in all.

  • Created and delivered training on the new data structure and management processes. 

Benefits Realized

  • Harmonization of data across business.

  • Requirement flowdown and traceability from source to end user.

  • Meeting migration deadlines ahead of schedule.

  • Cost savings by the decommissioning of TcSE, a redundant tool.
