18. 18 November 8 th, 2001 Is Interoperability Achievable? Two Levels of Interoperability/Convergence Standards Development Using Business Analysis and Design Techniques Agreeing on a Common Set of XML Design Rules Establishing a Standards Repository which will contain the Components of the Standards Standards Implementation Supporting the migration to the new standards Does the Benefit of Migrating to the New Standards Outweigh the Switching Costs?

19. 19 November 8 th, 2001 Is Interoperability Achievable? WG 10 Challenges General Issues Agreement is difficult Existing standards groups must consider their installed base - Vendors that support the standard’s growth - Potential switching costs WG 10 Specific Issues Business Modeling – Unified Modeling Language (UML) - New Technology/Concepts Standards Repository - Governance Issues - Intellectual Property XML - Implementation Changes

20. 20 November 8 th, 2001 Is Interoperability Achievable? Single XML Vocabulary? It is a matter of… Timing Organizations need to decide when they can migrate to this new way of developing standards Education Organizations need to understand/utilize the standards methodology Governance Organizations need to understand their role in future standards development through the standards repository
