Question | Answer |
ESS Characteristics | Tailored 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 |
Digital Dashboard | Integrates info from multiple sources & present in unified, understandable form |
ESS Capabilities | Consolidation- 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 |
Group-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 |
Digital Dashboard | Integrates 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 |
GDSS (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 |
Decision type Structured | Repetitive, routine, easy to automate, involve definite procedure for handling, "programmable" decisions |
Semi-structured | Not as well defined, only part of problem has clear-cut answer provided by accepted procedure, include human or subjective element |
Unstructured | Novel, unique, important, non-routine; no well-understood or agreed-upon procedure; decision maker must provide judgment, experience, intuition to solve |
Decision characteristics | Unstructured- senior mgt Semi-structured- middle mgt Structured- operational mgt |
Simon's decision making process | 1. Intelligence- understanding problem 2. Design- explore alts. 3. Choice- choose among alts. 4. Implementation- make chose alt work & monitor how well |
Quality dimensions of decisions | Accuracy Comprehensiveness Fairness Speed Coherence Due process |
Business intelligence | Applications & 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 |
Mgt 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 |
Decisions 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 |
Model-driven DSS | Model of situation/problem developed, various input factors changed & output changes measured |
Data-driven DSS | Use OLAP & data mining to analyze large pools of data in major corporate systems |
Components of DSS | DSS 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 |
DSS: Model Driven Analysis | Model- 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 |
DSS: Model Driven Analysis Continued | Sensitivity 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 |
Data Driven DSS | Spreadsheet tables answer multiple dimensions of questions Pivot table- displays 2+ dimensions of data in convenient format |
Data Visualization Tools | Present data in graphical form to help users see patterns & relationships in large quantities of data |
Geographic 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 |
Executive 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 |
