  1. Update to UCA-EIMonCalifornia ISO Enterprise Model Management System Project Brian Jacobsen Enterprise Model Management California ISO June 2012 OpenSGUser Group

  2. TheCase for Change • No enterprise-wide model strategy leads to • Fragmented repositories with common elements • Processes to merge models in run-time applications • Heavy burden on integration layer • Inherent risks of data mismatch errors in applications • Data duplication • Recreation of composite model (or reversion) is very difficult • Variations in semantics and overhead to ensure consistency • Excessive effort to ensure consistency when expanding models • Minimizing IT Project costs leads to inefficient enterprise model • Limited utilization of modeling standard (CIM)

  3. CAISO EMM Roadmap UCA EIM Vision Standardized information around the utility boundary Changes to information and technology End-to-End information management Single version of the truth A frame work to deal with many system sharing information Framework & Methodology to handle big data Unified model will not support this. Leveraging more than one model loosely (bridging models) Standards to support integration Operations & Analytics BI (historic data) Operational BI (near real-time)] • Develop CAISO Enterprise UML Model (CEM) • Establish UML maintenance strategy • Static model management • Centralized reference model (instance) management • Phased migration of legacy systems • Time based model • Fundamental business process changes • Dynamic model management • Initially, CEM transformations at integration layer • Roadmap for full CIM interoperability through SOA

  4. CAISO EMM Road Map – Step OneEnterprise Semantic Model (CEM) • Consistent information representation across business domains in stand-alone semantic model to be used as enterprise logical data model • Minimize semantic conflicts by referencing industry standard (CIM 15) • Upgrade from legacy CIM v10 based model • Strategy for maintenance and standards upgrade • Create autonomy for information model growth • Proceduralize Enterprise Model Strategy to enforce (internally) consistent use of CEM • SOA integration to standardize how data is exchanged

  5. CAISO EMM Road Map – Step TwoConsolidate Static Model Maintenance • Roadmap for migrating legacy models and repositories • Consolidation and centralization • Significant business process and continuity planning • Synchronize with legacytechnology roadmaps • Significant corporate investment • Requires high-level, long term management support • Multi-year investment • Measuring tangible and abstract ROI

  6. CAISO EMM Road MapAchievements and Current Activities • Four-phase EMM roadmap approved by officers and Board • CEM v1.0 is developed • Network model + commercial reference data • CIM v.15 (61968 + 62325), plus extensions • Migration to EA for UML maintenance tool set • EMM System Phase 1 in development • Proof of concept • Upgrade network model deployment to market systems • Implanting EMM strategy in IT development processes

  7. CAISO EMM Road MapNext Steps • Complete EMMS Phase 1 • Get EMMS Phase 2 scope ratified and project charter • Expand on static model maintenance and validation • First phase of static model SOA integration roadmap • Continue IT process improvements for EMM • Migrate dynamic model (transactional data models) to CEM in EA • Initially in legacy CIM 10 model • Roadmap for upgrade to CIM 15 (looking for catalyst projects) • Planning for EMMS Phase 3 : Migration of network Model to EMMS
