Enterprise Information Systems

• Executive information system– Computer system that allows executives access to

management reports• Drill-down capabilities• User-friendly

• Executive support system– Comprehensive executive support system

• Includes communication, office automation, analysis support, business intelligence

• Enterprise information system– Corporate-wide system – Not restricted to executives only– Business intelligence

3

Executive Information System (EIS)

• An extremely user-friendly computer-based information system for top-level executives

• Provides continuous and rapid access to critical-to-success (critical success factors) information

• Provides drill-down investigation capabilities using multidimensional analysis and OLAP

• Provides exceptions reporting and status reporting capabilities

4

Examples of Critical Success Factors (CSFs)

• Strengthen customer relations• Supporting the sales force in the field• Improving productivity• Securing R&D support from the government• Developing new products• Acquiring new technologies and capabilities• How promptly the company responds to market

(competitor’s) situation and the financial penalty for failing to do so

5

Comparing EIS to DSS

• EIS – Supports upper management in discovering problems and

opportunities– Repetitive analysis– High speed– GUI based

• DSS – Analyzes specific problem or opportunity– Ad hoc analysis– Effective– May have GUI

• Integration of EIS & DSS -- Executive Support System– Uses EIS output to launch DSS

• Data from same places– Integrates user roles– Third party software

6

Executive Support System (ESS)

• A comprehensive support system that integrates executive information system (EIS) and decision support system (DSS)

• Uses EIS output to launch DSS application• Provides drill-down multi dimensional investigation

capabilities• Provides capabilities to do trend analysis

7

Examples of OLAP/Multidimensional analysis packages used in EIS

• BrioQuery (Brio Technology Inc.)• Business Objects (Business objects Inc.)• Decision web (Comshare Inc.)• DataFountain (Dimensional Insight Inc.)• DSS Web (MicroStrategy Inc.)• Focus Fusion (Information Builders Inc.)• InfoBeacon Web (Platinum technology Inc.)• Oracle Express Server (Oracle Corporation)• Pilot Internet Publisher (Pilot Software Inc.)

Executive Support System (ESS) Contd.

• Assists top executives in conducting ad hoc analysis of current performance and projected operations to stimulate insights that may call for high-level decision-making

• Gives executives easy and rapid access to internal and external information relevant to their critical success factors (CSFs) – provides alerts, highlights exceptions

• Helps executives request and monitor CSFs via customized presentation attuned to an executive’s individual needs and tastes

Enterprise Information System

• Enterprise-wide system• Provides organizational-level support in operating

a firm and its problem-solving• Part of enterprise resource planning (ERP)

systems• For providing business intelligence to effectively

carryout customer relationship management (CRM)

• Leading up to enterprise information (corporate) portals and knowledge management systems

10

Organizational DSS (ODSS)

• One of the three types of DSS – individual, group, and organizational

• ODSS is used by individuals or groups, at several workstations in more than one organizational units, who make varied (interrelated but autonomous) decisions using a common set of tools

• ODSS focuses on an organizational task or activity involving a sequence of operations and actors where each individual’s activities must mesh closely with other people’s work

• ODSS provides computerized support for effective communication and coordination for collaborative problem solving

11

Supply Chain

• Refers to the flow of materials, information, and services from raw material suppliers through factories and warehouses to the end customers

• Also includes the organizations and processes that create and deliver these products, information, and services to the end customers

• It includes many activities such as purchasing, materials handling, production planning and control, logistics and warehousing, inventory control, and distribution and delivery

12

Supply Chain Management (SCM)

• To deliver an effective supply chain and do it effectively

• To plan, organize, and coordinate the supply chain’s activities

• SCM systems include (but not limited to):– Inventory management– Shipping management– Efficient purchasing– JIT– CRM– Collaboration along chain– Strategic partnerships– Reduce number of intermediaries– Outsourcing

13

The goals of modern SCM

• To reduce uncertainty and risks in the supply chain• To positively affect:

– Inventory levels– Cycle time– Processes, and– Customer service

• Hence, to increase profitability and competitive advantage

14

Enterprise Resource Planning (ERP)

• An ERP is a computer-based system that integrates all of an organization’s departments and functions

• An ERP controls all major business processes with a single software architecture in real-time

• The integrated solution promises benefits from increased efficiency to improved quality, productivity, and profitability

15

ERP software Vendors

• SAP• Baan• PeopleSoft• Oracle• J.D. Edwards• Computer Associates

16

ERP

• Very expensive• 2nd generation – doing better, Web-enabled• Susceptible to failure if an organization’s business

processes do not fit the ERP system’s model
