Business Driven Information Systems - Ch 2

Managerial Decision-Making Challenges (3)

(1) Managers need to analyze large amounts of information, (2) managers must make decisions quickly, (3) managers must apply sophisticated analysis techniques, such as Porter's strategies or forecasting, to make strategic decisions.

Organization Structure

(1) Operational - employees develop, control, and maintain core business activities required to run the day-to-day operations, (2) managerial - employees continuously evaluate company operations to hone the firm's abilities to identify, adapt to, and leve

Structured Decisions

Decisions that arise in situations where established processes offer potential solutions; operational level

Semi-structured Decisions

Decisions that occur in situations in which a few established processes help to evaluate potential solutions, but not enough to lead to a definite recommended decision; managerial level

Unstructured Decision

Decisions that occur in situations in which no procedures or rules exist to guide decision makers toward the correct choice; strategic level

Decision-Making Process Steps

(1) Problem identification. (2) data collection, (3) solution generation, (4) solution test, (5) solution selection, (6) solution implementation

Project

A temporary activity a company undertakes to create a unique product, service, or result

Metrics

Measurements that evaluate results to determine whether a project is meeting its goals

Critical Success Factors (CSFs)

The crucial steps companies perform to achieve their goals and objectives and implement their strategies

Key Performance Indicators (KPIs)

The quantifiable metrics a company uses to evaluate progress toward critical success factors; more specific than CSFs

Market Share

The proportion of the market that a firm captures; the firm's sales divided by the total market sales for the entire industry

Return on Investment (ROI)

The earning power of a project; the profitability of a project divided by the costs

Efficiency MIS metrics

Measure of the performance of MIS itself, such as throughput, transaction speed, and system availability

Effectiveness MIS metrics

Measure of the impact MIS has on business processes and activities, including customer satisfaction and customer conversion rates

Benchmarks

Baseline values the system seeks to attain

Benchmarking

A process of continuously measuring system results, comparing those results to optimal system performance (benchmark values), and identifying steps and procedures to improve system performance

Model

A simplified representation or abstraction of reality

Transactional Information

All the information contained within a single business process or unit of work, its primary purpose being to support the performance of daily operational or structured decisions

Online Transaction Processing (OLTP)

The capture of transaction and event information using technology to (1) process the information according to defined business rules, (2) store the information, and (3) update existing information to reflect the new information

Transaction Processing System (TPS)

The basic business system that serves the operational level (analysts) and assists in making structured decisions

Source Documents

The original transaction record

Analytical Information

All organizational information, its primary purpose being to support the performance of managerial analysis or semi-structured decisions

Online Analytical Processing (OLAP)

The manipulation of information to create business intelligence in support of strategic decision making

Decision Support Systems (DSSs)

Model information using online analytical processing (OLAP), which provides assistance in evaluating and choosing among different courses of action

What-If Analysis

Checks the impact of a change in a variable or assumption on the model

Sensitivity Analysis

A special case of what-if analysis, the study of the impact on other variables when one variable is changed repeatedly

Goal-Seeking Analysis

Finds the inputs necessary to achieve a goal such as a desired level of output

Optimization Analysis

An extension of goal-seeking analysis, finds the optimum value for a target variable by repeatedly changing other variables, subject to specified constraints

Executive Information System (EIS)

A specialized DSS that supports senior-level executives and unstructured, long-term, nonroutine decisions requiring judgment, evaluation, and insight

Granularity

The level of detail in the model or the decision-making process

Visualization

Graphical displays of patterns and complex relationships in large amounts of data

Digital Dashboard

Tracks KPIs and CSFs by compiling information from multiple sources and tailoring it to meet user needs

Consolidation

The aggregation of data from simple roll-ups to complex groupings of interrelated information

Drill-Down

Enables users to view details, and details of details, of information; the reverse of consolidation

Slice-and-Dice

The ability to look at information from different perspectives

Artificial Intelligence (AI)

Simulates human thinking and behavior, such as the ability to reason and learn

Intelligent Systems

Various commercial applications of artificial intelligence

Expert Systems

Computerized advisory programs that imitate the reasoning processes of experts in solving difficult problems

Neural Network

A category of AI that attempts to emulate the way the human brain works

Fuzzy Logic

A mathematical method of handling imprecise or subjective information

Genetic Algorithm

An artificial intelligence system that mimics the evolutionary, survival-of-the-fittest process to generate increasingly better solutions to a problem

Intelligent Agents

A special-purpose knowledge-based information system that accomplishes specific tasks on behalf of its users

Shopping Bot

Software that will search several retailer websites and provide a comparison of each retailer's offerings including price and availability

Virtual Reality

A computer-simulated environment that can be a simulation of the real world or an imaginary world

Customer-Facing Processes

Business processes that result in a product or service received by an organization's external customer; front-office processes

Business-Facing Processes

Business processes that are invisible to the external customer but essential to the effective management of the business; back-office processes

Business Process Modeling (Mapping)

The activity of creating a detailed flowchart or process map of a work process that shows its inputs, tasks, and activities in a structured sequence.

Business Process Model

A graphic description of a process, showing the sequence of process tasks, which is developed for a specific purpose and from a selected viewpoint

As-Is Process Models

Business process model that represents the current state of the operation that has been mapped, without any specific improvements or changes to existing processes

To-Be Process Models

Business process model that shows the results of applying change improvement opportunities to the current (As-Is) process model
