2 Enterprise Decision Support Systems n DSS to provide enterprise-wide support n Executives n Many decision makers in different locations n Enterprise Resource Planning (ERP) systems
3
3 Enterprise Systems: Concepts and Definitions n Executive information systems (EIS) n Executive support systems (ESS) n Enterprise information systems (EIS)
4
4 n DSS and ODSS n 1980s: Top execs get Executive Information Systems n 1995+’s: Move to everybody’s information systems and enterprise information systems n Definitions follow Evolution of Executive and Enterprise Information Systems
5
5 Executive Information System (EIS) n A computer-based system that serves the information needs of top executives n Provides rapid access to timely information and direct access to management reports n Very user-friendly, supported by graphics n Provides exceptions reporting and "drill-down" capabilities n Easily connected to the Internet n Drill down
6
6 Executive Support System (ESS) Comprehensive support system that goes beyond EIS to include n Communications n Office automation n Analysis support n Intelligence
7
7 Enterprise Information System n Corporate-wide system n Provides holistic information n From a corporate view n Part of enterprise resource planning (ERP) systems n For business intelligence n Leading up to enterprise information portals and knowledge management systems
8
8 Executives’ Role and Their Information Needs n Decisional Executive Role (2 Phases) 1. Identification of problems and/or opportunities 2. The decision of what to do about them n Flow chart and information flow (Figure 8.1) n Use phases to determine executives’ information needs
9
9 Methods for Finding Information Needs n Wetherbe's Approach 1. Structured Interviews –IBM's Business System Planning (BSP) –Critical Success Factors (CSF) –Ends/Means (E/M) Analysis 2. Prototyping n Watson and Frolick's Approach –Asking (interview approach) –Deriving the needs from an existing information system –Synthesis from characteristics of the systems –Discovering (Prototyping) Ten methods n Other Methods
10
10 Characteristics of EIS n Drill down n Critical success Factors (CSF) n Status access n Analysis n Exception reporting n Colors and audio n Navigation of information n Communication
11
11 Critical Success Factors (CSF) Monitored by five types of information 1.Key problem narratives 2.Highlight charts 3.Top-level financials 4.Key factors (key performance indicators (KPI)) 5.Detailed KPI responsibility reports
12
12 Characteristics and Benefits of EIS (Table 8.1) n Quality of information n User interface n Technical capability provided n Benefits
13
13 Comparing and Integrating EIS and DSS n Tables 8.2 and 8.3 compare the two systems –Table 8.2 - DSS definitions related to EIS –Table 8.3 - Comparison of EIS and DSS n EIS is part of decision support
14
14 n EIS vendors - easy interfaces with GSS n Some EIS built in Lotus Domino / Notes n Comshare Inc. and Pilot Software, Inc. - Lotus Domino/Notes-based enhancements and Web/Internet/Intranet links Integrating EIS and Group Support Systems
15
15 Traditional EIS Software n Major Commercial EIS Software Vendors –Comshare Inc. (www.comshare.com) –Pilot Software Inc. (www.pilotsw.com) n Application Development Tools –In-house components –Comshare Commander tools –Pilot Software’s Command Center Plus and Pilot Decision Support Suite
16
16 n EIS n Data access n Data warehousing n OLAP n Multidimensional analysis n Presentations n Web
17
17 Multidimensional Analysis n Easy to develop an EIS in an OLAP system n Most are Web-ready n Can tap into data in a data warehouse via the Web n Use advanced visualization tools
18
18 Representative OLAP / Multidimensional Analysis Packages n BrioQuery (Brio Technology Inc.) n Business Objects (Business Objects Inc.) n Decision Web (Comshare Inc.) n DataFountain (Dimensional Insight Inc.) n DSS Web (MicroStrategy Inc.) n Focus Fusion (Information Builders Inc.) n InfoBeacon Web (Platinum Technology Inc.) n Oracle xpress Server (Oracle Corporation) n Pilot Internet Publisher (Pilot Software Inc.)
19
19 Including Soft Information in EIS Soft information is fuzzy, unofficial, intuitive, subjective, nebulous, implied, and vague
20
20 Soft Information Used in Most EIS n Predictions, speculations, forecasts, estimates (78.1%) n Explanations, justifications, assessments, interpretations (65.6%) n News reports, industry trends, external survey data (62.5%) n Schedules, formal plans (50.0%) n Opinions, feelings, ideas (15.6%) n Rumors, gossip, hearsay (9.4%) Soft Information Enhances EIS Value
21
21 Organizational DSS (ODSS) n Three Types of Decision Support –Individual –Group –Organizational Hackathorn and Keen (1981)
22
22 n Organizational decision support focuses on an organizational task or activity involving a sequence of operations and actors n Each individual's activities must mesh closely with other people's work n Computer support is for –Improving communication and coordination –Problem solving
23
23 Definitions of ODSS n A combination of computer and communication technology designed to coordinate and disseminate decision-making across functional areas and hierarchical layers in order that decisions are congruent with organizational goals and management's shared interpretation of the competitive environment (R. T. Watson, 1990) n A DSS that is used by individuals or groups at several workstations in more than one organizational unit who make varied (interrelated but autonomous) decisions using a common set of tools (Carter et al., 1992)
24
24 n A distributed decision support system (DDSS). Not a manager's DSS, but supports the organization's division of labor in decision making (Swanson and Zmud, 1990) n Apply the technologies of computers and communications to enhance the organizational decision-making process. Vision of technological support for group processes to the higher level of organizations (King and Star, 1990)
25
25 Common Characteristics of ODSS (George, 1991) n Focus is on an organizational task or activity or a decision that affects several organizational units or corporate problems n Cuts across organizational functions or hierarchical layers n Almost always involves computer-based technologies, and may involve communication technologies n Can Integrate ODSS with Group DSS and Executive Information Systems n ODSS are an enterprise information system directly concerned with decision support
26
26 Supply and Value Chains and Decision Support n Supply chain: (originally) flow of materials from sources to internal use n Demand chain: flow from inside to customers
27
27 Supply Chain n The flow of materials, information, and services from raw material suppliers through factories and warehouses to the end customers n Includes the organizations and processes that create and deliver value to the end customers
28
28 Supply Chain Management (SCM) n To deliver an effective supply chain and do it effectively n To plan, organize, and coordinate the supply chain’s activities
29
29 SCM Benefits n Reduction in uncertainty and risks in the supply chain n Positively affect –inventory levels –cycle time –processes –customer service n Increase profitability
30
30 Supply Chain Components n Upstream n Internal supply chain n Downstream Involves product life cycle activities Example (Figure 8.2)
31
31 Supply Chain n Related to the Value Chain Model (Porter)
32
32 Supply Chain Problems n Uncertainty in the demand forecast n Uncertainty in delivery times n Quality problems n Poor customer service n High inventory costs n Low revenue n Extra costs
33
33 Solutions to Supply Chain Problems n Outsourcing n Buy, not make n Configure optimal shipping plans n Optimize purchasing n Strategic partnerships with suppliers n Just-in-time delivery of purchases n Reduce intermediaries n Reduce lead times (EDI) n Use fewer suppliers n Improve the supplier-buyer relationships n Build-to-order n Accurate demand by working with suppliers
34
34 Computerized Systems n MRP n ERP n SCM Integrating the supply chain
35
