The purpose of Information Systems in Business
is to support the achievement of the organization's strategic, tactical, and operational goals
· Interdependence (Relationship) of IT and Business
Businesses rely on information systems to help them achieve their goals; a business without adequate information systems will inevitably fall short. But information systems are also products of the businesses that use them. Businesses shape their information systems and information systems shape businesses.
Transformation
Emerging Technologies, Challenges, Time and Space Shift
Effects of Emerging Technology Organizations and Information Systems
Advances in technology enable quicker and cheaper information system changes, enabling the organization to be more agile in addressing changing customer wants and needs, even creating new market opportunities. The net effect is an ever-increasing interdependence between Business organizations' Information Systems and the outside environmental changes brought on by emerging technologies affecting both the internal workings of the business and its customers.
There is a price to pay for this transformation
primarily the loss of individual privacy.
How Information Systems Are Transforming Business
◦Mobile digital platform
◦Systems used to improve customer experience, respond to customer demand, reduce inventories, and more
◦Growing online news media readership
◦More knowledge of customers' locations, behaviors, tendencies

Strategic Business Objectives of Information Systems
1.Operational excellence
2.New products, services, and business models
3.Customer and supplier intimacy
4.Improved decision making
5.Competitive advantage
6.Survival
Operational Excellence
Information systems and technology are important tools in achieving greater efficiency and productivity
◦Example: Walmart's Retail Link system links suppliers to stores for superior replenishment system
Improvements of efficiency and productivity lead to higher profitability!
New Products, Services, and Business Models
Business model: describes how company produces, delivers, and sells product or service to create wealth
Information systems and technology are major enabling tools for new products, services, business models
◦Breakthroughs: Apple's iPad, Google's Android OS, and Netflix
◦Newer Examples: 'Alexa', Ring, Facial Recognition, Wind Turbines
Customer and Supplier Intimacy
Serving customers well leads them to return, increasing revenue and profits
◦Example: Amazon tracks browsing and purchasing to suggest other products for consideration and purchase
Intimacy with suppliers allows them to provide vital inputs, which lowers costs
◦Example: Manufacturers' access to suppliers' inventory systems to check availability before ordering.
Improved Decision Making
Accurate, Timely, and Complete Information Enables Objective, Data-Driven Decision-Making.
The Consequences:
◦Relying Solely on Forecasting, Experience, or Simply Luck
◦Creating the Wrong Product, Marketing, Cost
◦Over/Under Production
◦Mis-Allocation of Resources
◦Poor Production Quality
◦Missed Customer Expectations
Competitive Advantage
Delivering better performance
Charging less for superior products
Responding to customers and suppliers in real time
◦Examples: Amazon, Walmart, UPS
Survival
Information technologies as necessity of business
Industry-level changes
◦Example: Introduction of ATMs
Governmental regulations requiring record-keeping
◦Examples: HIPAA, Sarbanes-Oxley Act, Dodd-Frank Act
The Sarbanes-Oxley Act (2002)
requires that public firms keep all data, including e-mail, on record for 5 years
Dodd-Frank Act (2010)
requires financial services firms to develop extensive new compliance reports
HIPAA (Health Insurance Portability and Accountability Act
addresses the storage, retrieval, and access to protected patient health information, by health care providers, insurers and other related parties.
Definition of Information Technology
Although organization and management are important too, it's the technology that enables the systems and the organizations and managers who use the technology. Intranets and extranets'.
•Computer hardware, software, and data
•Data management technology
•Networking and telecommunications technology
•Networks, the Internet, intranets and extranets, World Wide Web
•IT infrastructure: provides platform that system is built upon
Intranets
Intranets are private networks used by corporations
Extranets
extranets are similar except that they are directed at external users
Internet
connects millions of different networks across the globe
Data
◦ are streams of raw facts.
Raw data from a supermarket checkout counter can be processed and organized to produce meaningful information
Information
◦ is data shaped into meaningful form.
such as the total unit sales of dish detergent or the total sales revenue from dish detergent for a specific store or sales territory.
information system
◦Set of interrelated components
◦Collect, process, store, and distribute information
◦Support decision making, coordination, and control
◦IS = IT + Procedures + People
Input
Captures raw data from organization or external environment
output
Transfers processed information to people or activities that use it
feedback
Output is returned to appropriate members of organization to help evaluate or correct input stage
Activities of an Information System
Activities of information systems produce information organizations need:
◦Input: Captures raw data from organization or external environment
◦Processing: Converts raw data into meaningful form
◦Output: Transfers processed information to people or activities that use it
◦Feedback: Output is returned to appropriate members of organization to help evaluate or correct input stage
Computer/Computer Program

Definitions of Business
•An organization or economic system, where goods and services are exchanged for one another or for money.
•Every ________ requires some form of investment and enough customers to whom its out can be sold on a consistent basis in order to make a profit
•_______ can be public or privately owned, not-for-profit or state-owned
Key Components of a Business
•Product, Goods, and Services
•Customers
•Management and Operations
•Investment, Sustainability
•Profit, Return
Organizations Definition and Features
•Use of hierarchical structure
•Separation of business functions
•Goals, management and leadership styles, types of tasks
•Accountability, authority in system of impartial decision making
•Routines and business processes
•Organizational politics, culture, environments, and structures
Levels in an Organization
Business organizations are hierarchies consisting of three principal levels: senior management, middle management, and operational management. Information systems serve each of these levels. Scientists and knowledge workers often work with middle management.
Senior management typically executives and board of directors (and their committees).
Middle Management typically vice presidents and director levels (manage overall business level functions)
Operational Management typically production and line level supervisors
Separation Of Business Functions
Organizations typically have some form of separate management structures for various business functions:
-Sales and Marketing
-Human Resources
-Finance and Accounting
-Supply Chain
-Manufacturing, Production
Information Systems must support all of these functions and their processes.
Routines/Activites (standard operating procedures)
•Precise rules, procedures, and practices developed to cope with virtually all expected situations
•Coincide with the Separation of Business Functions
Business Processes
Collections of routines
Business Organization
Collection of business processes
Routines and Business Processes
•Routines/Activites (standard operating procedures)
•Business Processes:
•Business Organization:
Organizational Culture and Politics
Culture - May be powerful unifying force as well as restraint on change
Encompasses set of assumptions that define goal and product
◦What products the organization should produce
◦How and where it should be produced
◦For whom the products should be produced
Influenced by
◦Management - Executives, Boards, etc
◦Workforce
◦Competition
◦Regulatory
Politics - Divergent viewpoints lead to political struggle, competition, and conflict.
Political resistance greatly hampers organizational change.
Organizational Resistance to Change
Information systems become bound up in organizational politics because they influence access to a key resource—information
Information systems potentially change an organization's structure, culture, politics, and work
Information technology controls innovation, as a critical element of the organization
Information Technology flattens organizations
◦Decision making is pushed to lower levels
◦Fewer managers are needed (IT enables faster decision making and increases span of control)
◦Organizations flatten because in authority increasingly relies on knowledge and competence rather than formal positions
Flattening Organizations
Information systems can reduce the number of levels in an organization by providing managers with information to supervise larger numbers of workers and by giving lower-level employees more decision-making authority.
Information Silo's'
Separation of Business Functions can create
· IT Organizations and governance
Often headed by Chief Information Officer (CIO)
◦Other senior positions include Chief Security Officer (CSO), Chief Knowledge Officer (CKO), Chief Privacy Officer (CPO), Chief Data Officer (CDO), Chief Information Security Officer (CISO)
◦Programmers
◦Systems Analysts
◦Information Systems Managers
◦Business Analysts
IT Governance
◦Strategies and Policies for Using IT in the Organization
◦Decision rights
◦Accountability
◦Capital Budgets
◦Project / Program Management
◦Organization of Information Systems Function
◦Centralized, decentralized
Strategic Plans
typically answer the "Why" question, in terms of overall direction of the organization:
◦Competitive / Marketplace, Information Systems, Management, Human Resources, Key Investments
◦Plans typically created by/for executives, boards
Tactical Plans
address the "What" question:
◦Specific Product Decisions, System Selection and Implementation, Resource Management (People, $$, etc.)
◦Plans typically created by/for vice presidents and director levels in the organization
As opposed to Operational
which answers the "How", "When", "Who", "Where" questions:
◦Process Improvement, Cost Containment Initiatives, System Programming, Training and Retention Programs, Maintenance and Sustainability
◦Plans typically created by/for operational managers in the organization
Business Information As An Asset
Information System is an instrument for creating value.
Investments in IT will hopefully result in superior returns.
◦Increases in productivity, revenue, long-term strategic positioning
◦Uncertainty - Good returns are not guaranteed, with considerable variation
Complementary assets 'hedge the bet' on asset investment.
◦Complementary Asset - Required to derive value from a primary investment
◦Invest in both organizational and management to make the technology investment work properly
Examples of Complementary Assets:
Organizational - Appropriate Business Model, Efficient Business Practices, IT governance
Managerial - Incentives for Management innovation, Teamwork and collaborative work environments, Data Management
Social - Internet and telecommunications infrastructure, technology standards
Key Considerations For Technical Strategy
Budgeting and Capital - Return on Investment in Building, Acquiring, Sustaining, and Protecting Assets
Synergies - The total is greater than the sum of its parts
◦Strategic Acquisitions (and merging technology)
Core Competencies - Activity where the organization is a "leader"
◦Rely on knowledge, experience, and sharing across the boundaries of business units
Competitive Landscape - Products, Customers, Competitors, Resources
◦Development of Market Share (Make vs. Buy vs. Acquire)
Pace of Change - Expected life of technological assets
◦How far in the future will your expected investment be relevant?
Virtualization - Physical assets no longer necessary
◦Virtual Office, Virtual Reality
Artificial Intelligence - Logical, self-learning technology
◦Self-Driving Cars, Clones, 3D-Printing
Ethics - Social Impact
Not always a simple 'right' or 'wrong'
Business Processes definition
Business processes
◦Sets of activities, routines, steps
◦Flows of material, data, information, knowledge
◦May be tied to functional area or be cross-functional
Businesses: Can be seen as collection of business processes
Business processes may be assets or liabilities
Structured Process
Support operational and structured managerial decisions and activities
Standardized
Usually formally defined and documented
Exceptions rare and not (well) tolerated
Process structure changes slowly and with organizational agony
Example: Customer returns, order entry, purchasing, payroll, etc.
Dynamic process
Support strategic and less structured managerial decision and activities
Less specific, fluid
Usually informal
Exceptions frequent and expected
Adaptive processes that change structure rapidly and readily
Example: Collaboration; social networking; ill-defined, ambiguous situations

BPMN Standards are established for graphic elements
Activity documentation part of a broader design process - UML
Common Software/Tools:
◦Microsoft Visio - Free from UTD Microsoft Download
◦LucidChart - Free Trial

Information Silos
An information silo exists when data are isolated in separated information systems.
Information system silos arise when:
•IS supports departmental processes rather than enterprise-level processes.
•Personal and workgroup support applications are created over time.
•Organizations grow, especially by merger and acquisitions.
What are the problems of information silos?
◦Data duplicated.
◦Data inconsistency.
◦Data isolated.
◦Disjointed processes.
◦Lack of integrated enterprise information.
◦Inefficiency: decisions made in isolation.
◦Increased cost for organization.

Organizational Knowledge
· Structured, Semi-Structured, Unstructured, Tacit, Explicit
· Knowledge - as an intangible asset to the organization
Three major types of knowledge in an enterprise
◦Structured, explicit knowledge
◦Reports, presentations
◦Formal rules
◦Semistructured documents
◦E-mails, videos
◦Unstructured, tacit knowledge
Tacit knowledge
is the kind of knowledge that is difficult to transfer to another person by means of writing it down or verbalizing it. For example, that London is in the United Kingdom is a piece of explicit knowledge that can be written down, transmitted, and understood by a recipient. However, the ability to speak a language, ride a bicycle, knead dough, play a musical instrument, or design and use complex equipment requires all sorts of knowledge that is not always known explicitly, even by expert practitioners, and which is difficult or impossible to explicitly transfer to other people.
· Explicit
· Knowledge - as an intangible asset to the organization
Knowledge that can be readily articulated, codified, accessed and verbalized. It can be easily transmitted to others. Most forms of explicit knowledge can be stored in certain media. The most common forms of explicit knowledge are manuals, textbooks, documents, procedures, and how-to videos. Knowledge also can be audio-visual. Engineering works and product design can be seen as other forms of explicit knowledge where human skills, motives and knowledge are externalized
4 Stages of Knowledge Management
1. Knowledge Acquisition
◦Documenting Tacit and Explicit knowledge
◦Storing documents, reports, presentations, best practices
◦Unstructured documents (e.g., e-mails)
◦Developing online expert networks
◦Creating Knowledge
◦Tracking Data from Transaction Processing Systems and External Sources
2. Knowledge Storage
-Knowledge storage includes the ways in which knowledge is stored as well as the importance of management in creating and maintaining repositories of knowledge.
◦Databases
◦Content and Document Management Systems

◦E-mail, instant messaging
◦Search engines, collaboration tools
◦A deluge of information?
◦Training programs, informal networks, and shared management experience help managers focus attention on important information.
4. Knowledge Application
-the need to see and evaluate knowledge in terms of organizational capital and return on investment.
◦New business practices
◦New products and services
New markets

Knowledge Work (and Workers) System
Augmented reality (AR) is a related technology for enhancing visualization. AR provides a live direct or indirect view of a physical real-world environment whose elements are augmented by virtual computer-generated imagery. The user is grounded in the real physical world, and the virtual images are merged with the real view to create the augmented display
◦VRML - Virtual Reality Modeling Systems
Intelligent Techniques
Expert Systems (Rules, Inferences), Case-Based, Fuzzy Logic, Neural Networks, Genetic Algorithms, Intelligent Agents
- Expert Systems (Rules, Inferences
An expert system contains a number of if/then rules to be followed. The rules are interconnected, the number of outcomes is known in advance and is limited, there are multiple paths to the same outcome, and the system can consider multiple rules at a single time. The rules illustrated are for simple credit-granting expert systems.
An inference engine works by searching through the rules and "firing" those rules that are triggered by facts gathered and entered by the user. Basically, a collection of rules is similar to a series of nested IF statements in a traditional software program; however, the magnitude of the statements and degree of nesting are much greater in an expert system.
This graphic illustrates the types of rules that might be used by salespeople to determine whether or not to add a client to a prospect database. Using this chart, what would happen to a client that was determined to have an income of $80,000 and was given Financial Advice.
Case-Based Reasoning
Descriptions of past experiences of human specialists (cases), stored in knowledge base
System searches for cases with characteristics similar to new one and applies solutions of old case to new case
Successful and unsuccessful applications are grouped with case
Stores organizational intelligence
CBR found in:
◦Medical diagnostic systems
◦Customer support
Fuzzy Logic
Rule Based Technology that represents imprecision used in linguistic categories (e.g. cold, cool, etc.) to represent a range of values
Describe situation linguistically, then represent in a small number of rules
Used when if-then rules are extremely difficult:
◦Autofocus Systems
◦Detecting Medical Fraud
Neural Networks
Find patterns and relationships in massive amounts of data too complicated for humans to analyze
"Learn" patterns by searching for relationships, building models, and correcting over and over again
Humans "train" network by feeding it data inputs for which outputs are known, to help neural network learn solution by example
Used in medicine, science, and business for problems in pattern classification, prediction, financial analysis, and control and optimization
Genetic Algorithms
Useful for finding optimal solution for specific problem by examining very large number of possible solutions for that problem
Conceptually based on process of evolution
◦Search among solution variables by changing and reorganizing component parts using processes such as inheritance, mutation, and selection
Used in optimization problems (minimization of costs, efficient scheduling, optimal jet engine design) in which hundreds or thousands of variables exist
Able to evaluate many solution alternatives quickly
Intelligent Agents
Work without direct human intervention to carry out repetitive, predictable tasks
◦Deleting junk e-mail
◦Finding cheapest airfare
Use limited built-in or learned knowledge base
◦Some are capable of self-adjustment, for example: Siri
Chatbots
Agent-based modeling applications:
◦Model behavior of consumers, stock markets, and supply chains
◦Predict spread of epidemics
