Enterprise Process Modeling Concept and Architecture of Integrated Information System

1. IEEM 5352E-Enterprise Integration Enterprise Process Modeling Concept and Architecture of Integrated Information System Dr. Amy Trappey IEEM, NTHU

2. Architecture of Integrated Information Systems • Framework concept to describe enterprises and application system development • Focused on business processes IEEM, NTHU

3. Enterprise Process Modeling Concept • The concept creates a guideline for developing, optimizing and implementing integrated application systems. Meantime, it shows business administration specialists how to view, analyze, document and implement information systems. IEEM, NTHU

4. Why an Enterprise need a Framework for Integrated Information Systems • Business software solutions comprise modules for accounting, purchasing, sales, finance, production planning, etc (with a high degree of complexity). Many corporate and external business partners are involved in the implementation of Information Systems. This becomes apparent in light of seamlessly integrated data processing, where data is shared by multiple applications. • For example -- CIM in manufacturing companies, IS-supported merchandise management systems for retailers, electronic banking in financial institutions, IS-oriented concepts implemented in enterprises. • 4M Modules – Money (Accounting, Finance, ..); Man (HR); Manufacturing (Procurement, Production, …); Marketing (Sales, Distribution, …) IEEM, NTHU

5. “Real World”: The actual situation of the company Problem Define the requirements: Analyze “as-is” and design “to-be” Business concept Design specification: “Translate” into data structures, hardware, ... IT Concept Technical implementation: Create physical hardware structure, ... Implementation Information technology “Enablers”: PC’s, networks, standards, databases, ... IEEM, NTHU

6. Business Administration Issue Information Technology Organization Effort vs. Software Effort 5:1 User’s target profile of concept Requirements Definition (Semantic Models) Reconciling target concept and system solution Design Specification Implementation Description Profile of traditional standard software solution IEEM, NTHU

7. Information Technology Reduce Organization Effort Business Administration Issue User’s target profile of concept Reducing time and effort by using reference models Requirements Definition (Semantic Models) Modeling documentation of standard software solution (SSS) for reconciling with target concept Tool-supported reconciling of target concept with system solution Design Specification Automatic customizing of standard solution Implementation Description Profile of model-based standard software solution IEEM, NTHU

8. Key Functionality • Offers a framework (architecture) to completely describe standard software solutions (SSS). • Integrates the most suitable methods for modeling information systems (IS) into the architecture, develops methods for describing business processes. • Provides reference models as tools for the administration of application know-how, for modeling and analyzing system requirements. IEEM, NTHU

9. Key Functionality (cont.) • Industry-specific reference model for specific business processes (order management process, procurement process, customer service process, etc) • For example, SAP (for electronic industry) procurement process reference model. • Leveraging SSS, the business engineering tool(s) provide architectures for managing business processes. Using workflow systems, it is loosely linked with software “building blocks” (business objects). modules IEEM, NTHU

10. Key Functionality (cont.) • You’re involved in procurement process. You will have a “procurement” workflow management system that you need to comply with. • For example, in your flow, you need to take care of 3 procurement approval tasks. • Provides the framework for describing the assembly of software components (resulting in business IS) which are ideal for configuring workflow systems, generating screens and determining parameters for applications. IEEM, NTHU

11. Basic Business Process ModelThe Initial Business Process Model • Responsible entities and their relationship: organization, interaction • Function flow: function, organization, function flow and organization flow • Output flow • Information flow: information services objects and other information objects • Consolidated business process model IEEM, NTHU
