IST 421: Advanced Systems and Enterprise Integration

EI Roadmap Source: GBR, 2005, p. 18

Process Integration Architecture � Improve a process to increase business efficiency � Provides business level view of the end-to-end process � Processes are technology-independent � Role of process integration architecture � � � Process models and definitions Business level view of end-to-end process Dashboards to track key performance indicators (KPIs) Process simulation Alignment between IT and business Start here (top-down) to build Enterprise Integration Architecture Source: GBR. p. 159 -161

Background � 1950 s – 1980 s: � Quality Movements � Dr. Edward Deming � 1990 s � Business Process Reengineering � � Improvements in managing business processes lead to improvements in overall business and significant competitive advantage Process variations introduce product defects Plan-Do-Check-Act (PDCA) Six-Sigma Lack of technology support for BPR 2000 s � Business Process Management � � Plan: Business process modeling Do: Automate and integrate Check: Monitoring tools and dashboards Act: Simulation and analytical tools Source: GBR. p. 161 -162 Business Process Automation (BPA) Business Process Integration (BPI) Business Activity Monitoring (BAM)

Business Process Modeling � Process models are organizational assets � Processing modeling standards prevent technology lock-in � BPMN: Business Process Modeling Notation: For business processes (OMG) � BPEL: Business Process Execution Language: For web services (OASIS) � UML: Unified Modeling Language: For software development (esp. object oriented) (OMG) � BPMI: Business Process Management Initiative (AKA Business Modeling & Integration - BMI): Develop specification of integration models (OMG) � IDEF: Integration DEFinition: For software engineering and design using Structured Analysis and Design Technique (US-Do. D) Source: GBR. p. 169 -171 More BPM standards

Process Flow Models � Combination of Events, Actors, Software services, Messages, Business rules � The modeling methods and tools vary with industry Source: http: //www. ariscommunity. com/videos/learn-how-model-bpmn-diagrams-aris-express
