Study Notes
Introduction to Information Systems in Organizations
- Information systems are an organization's most valuable resource
- Data is raw facts
- Information is data organized to be valuable
- Knowledge involves understanding information for tasks
- Valuable information helps people perform tasks efficiently and effectively
- Inaccurate data results in lost potential customers and lower satisfaction
What is an Information System?
- An information system (IS) is a set of interrelated elements that collect, process, store, and disseminate data and information.
- It uses feedback mechanisms for monitoring and controlling operations, ensuring goals are met.
- Computer-based information systems (CBIS) use hardware, software, databases, networks, people, and procedures to accomplish operations.
- IS processes data into information.
Fundamental Types of IS
- Personal IS improve individual productivity
- Group IS improve communication and collaboration among a workgroup
- Enterprise IS facilitate structured interactions among employees, customers, suppliers, etc.
- Organizational complements (well-trained workers, better teamwork, etc.) improve IS outcomes
Information Systems in Organizations
- Organizations are structured and managed to meet their mission or group goals.
- There are relationships between members and related activities.
- Processes define roles, responsibilities, and authorities for completing tasks.
- Organizations are open systems, influenced by their surroundings.
Value Chains
- Value chains are a series of activities transforming inputs into outputs.
- Supply chains are key value chains, particularly in manufacturing.
- Supply chain management (SCM) encompasses activities to deliver products to customers efficiently.
- Involves steps such as Receiving, Raw material storage, Shipping, Manufacturing, Advertising, Selling, etc
Changes in the Organization
- Reengineering involves radically redesigning business processes, structures, information systems, and values for better results.
- Continuous improvement (Kaizen) emphasizes constant improvements in business processes and adds value to products, services.
Soft Side of Implementing Change
- Change management models guide individuals and organizations through change.
- Lewin's Change Model has three stages: Unfreezing, Moving/Changing, Refreezing.
Lewin's Force Field Analysis
- Driving forces encourage change; restraining forces hinder it
- Analyzing both can determine if change is possible
- Understanding these factors is crucial for implementing successful change.
Technology Acceptance Model (TAM)
- TAM explains factors that result in better attitudes toward a new information system
- Factors are related to perceived usefulness (U), perceived ease of use (E), attitude toward using (A), and behavioral intention to use (BI).
Important Technical Skills for IS Workers
- Analyzing large data sets, building applications, supporting expertise, project management, networking, cloud computing, security, data center operations, are important technical skills.
Primary Functions of the IS Organization
- Operations group: Data center management, system operations, security analysis, local area network administration.
- Development group: Software development, systems analysis, programming, web development.
- Support group: Database administration, system support, and responding to user inquiries about IS.
Hardware
- Hardware are digital devices that can be touched. These include desktop computers, laptops, mobile phones, tablets, e-readers, storage devices(USB drives), input devices(keyboard, mouse, scanner, etc.) and output devices(printers, speakers)
- Digital technologies are integrated into many everyday objects (e.g., refrigerators with monitors). Electronic signals are converted into binary values (0s and 1s), often represented as bits. A group of eight bits is called a byte.
- The CPU (Central Processing Unit) sequences instructions, executes them, and makes decisions using arithmetic and logic units.
- Multiprocessing involves executing multiple instructions simultaneously.
Software
- Software controls computer functions (system software and application software)
- Systems software coordinates hardware and other programs. Includes operating systems, and utilities.
- Application software solves computing problems and performs specific tasks. This includes word processing, spreadsheets, database applications, and presentation graphics.
- Types of operating systems include personal, workgroup, enterprise, and cloud-based options.
Cloud Computing
- A distributed computer model where shared pool of virtualized resources is provided over a network; Primarily the internet.
Edge Computing
- Allows data from Internet of Things (IoT) devices to be analyzed at the edge of the network (rather than sending all data to a central location)
Hardware Platform Trends
- Green computing (green IT): Concerned with the efficient and environmentally responsible design, manufacture, operation, and disposal of IS-related products.
Software Trends
- Open-source software: Free to use and modify, not limited by specific operating systems or hardware technologies.
- Cloud-based software services: Accessible via the internet, offering various applications, such as apps and mashups
Data Fundamentals
- Data is organized into different levels: bits, bytes, fields, records, files, and databases.
Database and Big Data
- Databases provide structured data access, storage, and management.
- Database Management Systems (DBMS) enables organizations to structure, manage and control data.
- Non-Relational DBMS (NoSQL) handle unstructured data; especially big data.
- Big Data refers to large, diverse data sets with high volume, velocity, and variety.
- Big Data Uses: Retail, advertising, marketing agencies, hospitals, and consumer product companies.
Data Governance
- Data governance is responsible for ensuring reliable, accessible, and timely data for use by organizations
- Data governance defines the roles, responsibilities, and processes for data management within an organization, as well as data leadership, participation, oversight, and effective problem-resolution.
Data Steward
- Data steward is responsible for critically important data elements.
