- 1ESS CharacteristicsTailored to individual
Easy to use
Provide data related to org
Sophisticated graphics
Future-oriented
Support for unstructured problems
Support consolidation, drill down, slice & dice capabilities - 2Digital DashboardIntegrates info from multiple sources & present in unified, understandable form
- 3ESS CapabilitiesConsolidation- aggregation of info & simple roll-ups to complex groupings of interrelated info
Drill-down- details of details of info
Slice & dice- look at info from diff. perspectives - 4Group-Decision-Support Systems (GDSS)Interactive, computer-based systems facilitating solving of unstructured problems by set of decision makers
Used in conference rooms
Promote collaborative atmosphere by guaranteeing contributor's anonymity
Support increased meeting sizes with increased productivity - 5Digital DashboardIntegrates info from multiple sources & presents in unified, understandable format, charts & graphs, key performance indicators & critical measurements to support executive, up-to-minute snapshots of info & assist executive in trends & potential problems
- 6GDSS (Group Decision-Support Systems)Interactive system that facilitates solving of unstructured problems by set of decision makers, used in conference rooms, promote collaborative atmosphere with anonymity, support increased meeting sizes with increased productivity
- 7Decision type StructuredRepetitive, routine, easy to automate, involve definite procedure for handling, "programmable" decisions
- 8Semi-structuredNot as well defined, only part of problem has clear-cut answer provided by accepted procedure, include human or subjective element
- 9UnstructuredNovel, unique, important, non-routine; no well-understood or agreed-upon procedure; decision maker must provide judgment, experience, intuition to solve
- 10Decision characteristicsUnstructured- senior mgt
Semi-structured- middle mgt
Structured- operational mgt - 11Simon's decision making process1. Intelligence- understanding problem
2. Design- explore alts.
3. Choice- choose among alts.
4. Implementation- make chose alt work & monitor how well - 12Quality dimensions of decisionsAccuracy
Comprehensiveness
Fairness
Speed
Coherence
Due process - 13Business intelligenceApplications & tech to help users make better decisions
1. Data from biz environment
2. Biz intelligence infrastructure
3. Biz analytics toolset
4. Managerial users & methods
5. Delivery platform (MSS, DSS, ESS)
6. User interface - 14Mgt Information Systems (MIS)Help managers monitor & control biz by providing info on firm's performance
Regularly scheduled reports based on data from TPS
Exception reports- when situation is unusual or requires MGT action
Trigger points- parameters or criteria for initiating exception report - 15Decisions Support System (DSS)Interactive info system combining data & sophisticated mathematical & statistical models for complex analysis
Support semi and unstructured decision making
Support at all org levels
Incorporate human element
Use internal & external data - 16Model-driven DSSModel of situation/problem developed, various input factors changed & output changes measured
- 17Data-driven DSSUse OLAP & data mining to analyze large pools of data in major corporate systems
- 18Components of DSSDSS database- collection of current/historical data from apps or groups
DSS user interface- permits easy interaction between users of DSS and software program and analysis tools - 19DSS: Model Driven AnalysisModel- simplified representation of reality that illustrates components of phenomenon
Statistical models help establish relationships
Optimization models- determine optimal resource allocation to maximize/minimize specified variables
Forecasting models- used to forecast future performance - 20DSS: Model Driven Analysis ContinuedSensitivity analysis model asks "what-if" repeatedly to determine impact on outcome of changes
Makes hypothetical change to data and observes "what will happen"
Goal seeking analysis- setting target value to achieve and determining how to get it - 21Data Driven DSSSpreadsheet tables answer multiple dimensions of questions
Pivot table- displays 2+ dimensions of data in convenient format - 22Data Visualization ToolsPresent data in graphical form to help users see patterns & relationships in large quantities of data
- 23Geographic Information Systems (GIS)Use data visualization tech to analyze & display data in form of digitized maps
Support decisions that require knowledge about geographic distribution of people/resources - 24Executive Support Systems (ESS)Help senior managers address strategic issues & long-term trends
Address non-routine decision making
Draw summarized info from MIS, DSS & data from external sources
Use portal with web interface to present content
