IST 421: Advanced Systems and Enterprise Integration Week 1

Systems � System: a set of discernible, interacting parts or subsystems that form an integrated whole that acts with a single goal or purpose � System Integration: bringing together component subsystems into one system and ensuring that the subsystems function together as a system � An enterprise is a system

Drivers for Systems Integration Computer networks and information processing � Globalization � Need for organizational agility � Personalize products and services � Legal environment and regulatory compliance � Source: Sherif, 2010, p. 4 � Business agility Reduce costs � Increase revenue � Customer satisfaction � Business Process Improvement � Source: GBR, 2005, p. 11 -15

Drivers for Systems Integration � Systems integration is not merely a technical issue. Source: GBR, 2005, p. xix

Enterprise Integration � Facilitating information, control, and material flows across organizational boundaries by connecting all the necessary functions and heterogeneous functional entities (information systems, devices applications, and people) in order to improve communication, cooperation and coordination within this enterprise so that the enterprise behaves as an integrated whole, therefore enhancing its overall productivity, flexibility, and capacity for management of Source: Sherif, 2010, p. 4 change (or reactivity) � Make the enterprise an integrated whole by � Facilitating – flow of information, control, material across boundaries � Connecting – functions and functional entities � Improving – communication, cooperation, coordination � Enhancing – productivity, flexibility, capacity for managing change

Enterprise Integration Enterprise Architecture Business process layer, e. g. ERP, CRM Application layer, e. g. Distributed applications, SOA Data layer, e. g. Database, Data warehouse, Data ma Infrastructure layer, e. g. LAN, Internet, VPN, etc.

Business Imperative � Enterprise integration process begins with business problems…. (or opportunities) � The problem is not whether the technology exists; it’s which technology to use to solve the business problem … (or to exploit an opportunity) Source: GBR, 2010, p. 4

Business Imperative � Cisco Systems: � Business problem: Focus on real-time metrics for rapid decision making � Solution: Integration of data from diverse systems in Source: GBR, 2010, p. 6 diverse locations � Fedex � Business problem: Package delivery management � Solution: Hand-held devices integrated with back-office core systems Source: GBR, 2010, p. 9

Conclusions � Enterprise integration engages business processes, people, and technology � There are multiple levels of enterprise integration � Enterprise integration is driven by business needs
