A group of components that interact to achieve some purpose is referred to as a(n)

System:a set of elements or components that interact toaccomplish goals•Components of a system•Input•Processing•Output•Feedback

Principles of Information Systems, Seventh Edition16System Components and Concepts•System boundary:defines the system and distinguishesit from everything else (i.e., the environment)•Configuration:the way system elements are organizedor arranged•Systems can be classified as simple or complex, open orclosed, stable or dynamic, adaptive or nonadaptive, andpermanent or temporary

Principles of Information Systems, Seventh Edition17Table 1.3: Systems Classifications andTheir Primary Characteristics

Principles of Information Systems, Seventh Edition18System Performance and Standards•Efficiency:a measure of what is produced divided bywhat is consumed•Effectiveness:extent to which system attains its goals•System performance standard:a specific objective of asystem

Principles of Information Systems, Seventh Edition19System Variables and Parameters•System variable:quantity or item controlled by thedecision maker•System parameter:value or quantity that cannot becontrolled (e.g., the cost of a raw material)

Principles of Information Systems, Seventh Edition20Modeling a System•Model:an abstraction that is used to represent reality•Four major types of models: narrative (based on words);physical (tangible); schematic (graphic representation);mathematical (arithmetic representation)

Principles of Information Systems, Seventh Edition23Input, Processing, Output, Feedback•Input:activity of gathering and capturing raw data•Processing:converting or transforming data into usefuloutputs•Output:production of useful information, usually inform of documents and reports•Feedback:output used to make changes to input orprocessing activities

Principles of Information Systems, Seventh Edition24Computer-Based Information Systems•Computer-based information system (CBIS)•A single set of hardware, software, databases,telecommunications, people, and procedures that areconfigured to collect, manipulate, store, and process datainto information•Examples: a company’s payroll systems, order entrysystem, and inventory control systems

Principles of Information Systems, Seventh Edition26Business Information Systems•Most common types of information systems used inbusiness organizations include:•Electronic and mobile commerce systems•Transaction processing systems•Management information systems•Decision support systems

Principles of Information Systems, Seventh Edition27Electronic and Mobile Commerce•E-commerce:any business transaction executedelectronically between parties•Parties involved include companies (B2B); companiesand consumers (B2C); consumers and other consumers(C2C); businesses and the public sector; consumers andthe public sector
