2. Enterprise Information Architecture

3. Enterprise Information Architecture Four Essential Contexts • Content and Content Structure • Data and Unstructured Information • Standards and Procedures • People – Company Structure • Communities, Users, Central Team • Activities – Business processes and procedures • Central team - establish standards, facilitate • Technology • CMS, Search, portals, taxonomy tools • Applications – BI, CI, Text Mining

4. Content & Content Structures • Content • Huge variety of types, sources, and uses • Structured data, unstructured documents, web pages, email • Semantic Infrastructure – Foundation • Essential content structures – taxonomies, metadata, vocabularies, synonyms, ontologies, best bets • Standards, publishing policies and procedures • Metadata standards, common taxonomies • Integration of metadata into publishing process

5. Content Creation, Customer Services Agency Activities Activity Text Mining, Alerts, Personalization Services SEARCH / PORTAL / EAI / Content Management Technology People Policies Tools Content Structure Data base schemas, Metadata, Taxonomies, Vocabularies, Personas People Data External Documents Content Layer Drives Email Internet Subscriptions Tacit Knowledge Databases

6. Engineering Design Production Planning Sales Finance Shop Floor execution Controlling Maintenance Functions of Enterprise Inventory Enterprise Quality Procurement

8. Systems from a Functional Perspective Business processes & Information Systems • Def: Manner in which work is organized, coordinated, and focused to produce a valuable product or service. -- Cross-Functional Business Processes transcend boundary between sales, marketing, manufacturing, and research and development (e.g., order fulfillment process…) • Ways in which management chooses to coordinate work

9. Examples of Business Processes

10. Typical problem faced by an Enterprise • Focus on ‘Functions’ rather than ‘Processes’ • Applications developed over time. • Inconsistent, redundant Data • Time lag in information delivery • Managerial Control Difficult • Process Productivity Monitoring Difficult • Reaction to change slow

11. Enterprise Information System Integrated Enterprise Enterprise wide information system integratesvarious functionalities within an enterprise

12. Major Types of Information Systems

13. Systems from a Functional Perspective major functions & application of important function wise systems Sales and Marketing Systems Manufacturing and Production Systems Financing and Accounting Systems Human Resource Systems

14. Sales and Marketing Systems Major functions of systems: • Sales management, market research, promotion, pricing, new products, market gap analysis Major application systems: • Sales order info system, market research system, pricing system

15. Sales and Marketing Systems

16. Manufacturing and Production Systems Major functions of systems: • Scheduling, purchasing, shipping, receiving, engineering, operations Major application systems: • Materials resource planning systems, purchase order control systems, engineering systems, quality control systems

17. Manufacturing and Production System

18. Enterprise Resource Planning ERP Definition of an ERP system ERP or Enterprise Resource Planning systems are software systemsfor businesses management encompassing modules supporting functional areas such as sales and marketing, finance, production, distribution accounting, human resource management, maintenance, inventory management, project management, transportation and e-business etc

19. Definition of an ERP system • ERP is a commodity -- product in the form of software • SAP, Oracle Applications, PeopleSoft, JD Edwards, Greatplains etc. are world’s leading ERP packages • The market leader is “SAP”

20. Features of an ERP system • Architecture of ERP system facilitates transparent integration of modules providing flow of information between all function within enterprise in real time. • Many different software are replaced by one integrated system. • Reliable information access through common DBMS • Eliminates data and operational redundancies (no duplication of work or data entries etc.)

21. Features of an ERP system • Cost reduction through time saving, improved control by organizational wise analysis of organizational decisions. • Delivery and cycle time reduction • Scalable systems • Global outreach through extended modules such as CRM or SCM • E-Business • Providing business solutions in support of core processes • Process-oriented view cutting across functions of an enterprise • Huge potential for customizing

22. Business and Technical Benefits • Automation of business transactions • Flexibilityin changing the system catering to newer business processes. • Coordination across business functions • Coordination across geographical distances resulting in better Managerial control • Consistent information and interface thus easier to understand and work in • Single system

23. Prime Reasons for Implementing ERP • Need for common platform • Process improvement. • Data visibility that could be used to improve operating decisions. • Operation cost reductions. • Increased customer responsiveness. • Improved strategic decision making • Personal Improvement
