Capabilities of Enterprise Information System
Drill-down paths-Provide details of any summarized information
-Supported by star or snowflake schemas
Critical success factors-Strategic, managerial, or operational
-Sources: organizational, industrial, environmental
Types of information monitored:•Key problem narratives•Highlight charts•Top level financials•Key factors•Detailed key performance indicator responsibility reports

Capabilities of Enterprise Information System
Status Access-the latest data of key indicators can be accessed at any Time via network.
AnalysisAnalytic Capabilities are available in executive system information
Exception reporting -based on the concept of Management by exception
Navigation of informationLarge amounts of data can be analyzed
Audio and VisualUse of colors and sounds
CommunicationsE-mail, news groups, call for a meeting.

Characteristics of Enterprise Information System
Quality of information -produces correct information -produces complete & validated information
User interface - Allows secure &confidential access to information - Has short response time
Technical capability provided -Access electronic mail -provides forecasting

Data warehouses are used as the single data sources for EIS
Once data are accessed and provided, analysis and display become important .
• Combination of multidimensional analysis with OLAP allow to display data in
- Spreadsheets and graphics formats - slice-and-dice - Web-ready
EIS Data Access and Use

Organizational Decisional Support Systems(ODSS)
) -ODSS:( A DSS that is used by individuals or groups at several workstations in more than
One organizational unit who make varied (intrrelated but autonomous ) decisions using common set of tool.
-Characteristics of(ODSS):1 (Focused on organizational task or activity

Supply chains and the value chains
![Page 22: Enterprise Information Systems](https://reader035.fdocuments.net/reader035/viewer/2022081417/568145c2550346895db2ccf3/html5/thumbnails/22.jpg)
Supply Chains
Supply Chains: refers to flow of Material , information, services from suppliers through factories and warehouses to the end coustmer
-Supply chain management: Planning, organization, and coordination of supply chain activities
-Componnents of Supply Chains:
-Upstream = suppliers
-Internal supply chain = changing inputs to outputs
-Downstream = distribution

Supply Chains and the Value Chains
--The concept of the Supply Chains is related to the concept of Value Chains and value system
-Porter’s value chain model: -Primary activities (Inbound logistics, Operations,Outbound
logistics, Marketing and sales,Customer service)
-Support activities (Organization’s infrastructure, Human resource management, Technology development, Procurement
-all Support activities can Support any or all of the Primary activities

Value System
-Value chain is part of larger stream called value system.
-Includes tiers of suppliers.
