Organizations use standards and frameworks to improve supply chain performance for different reasons of fast changing markets and competition, were methods of dealing with issues is decisive to their success. The development of Enterprise Architecture framework "EA" based on Service Oriented Architecture "SOA", Architect applications define almost everything in enterprises, improves the ways of doing things in industries, services and their supply chains, in a Business-IT alignment dimension. Adding Lean Six Sigma "LSS" features in EA environment is a challenge and opportunity to provide a solid extended supply chain systems network. Modelling this coexistence in an Architect is expected to add a visual follow-up to the supply chain as EA viewpoint and push it to a new level. A conceptual model suggested to depict the Supply Chain Operations, LSS and EA. For this reason a high level Enterprise Architect application used to combine a cyclic activities represented to highlight and emphasis the features, principles and gains of an integrated new tools, supports a knowledge system development and achieves a safe and secure supply chain capability. The research outcomes suggest an industrial engineering era that treats Enterprise Architecture as an effective tool.
