Information Systems Fundamentals An Information System is a set of (primarily) electronic components that collect, analyze and disseminate data and information to meet an objective. • Data: raw facts, e.g. text, image, audio, video. By itself, data cannot help us make decisions • Information: aggregation, analysis and selection of data that enables organizations to meet objectives. Some characteristics of information: • accurate • reliable • relevant • verifiable • valuable
Information Systems Fundamentals (cont’d) • System: a collection of elements or components that interact to accomplish goals. Composed of: • Inputs • Processing mechanisms • Outputs • Feedback/assessment • Many processes, whether or not they have a significant IS component, can be viewed as systems: • Personnel management • University admissions • Production and inventory management • Criminal justice system
Information Systems Fundamentals (cont’d) • Organizations may be classified according to the systems they employ: • Simple vs. complex • Open vs. closed • Stable vs. dynamic • Adaptive vs. nonadaptive • Permanent vs. temporary • System performance can be measured along three dimensions: • Efficiency • Effectiveness • Equity (fairness)
Information Systems Fundamentals (cont’d) • Systems are designed, implemented and managed using models: abstractions of reality that allow us to apply principles assumed to hold true for many different systems • Model types: • Narrative model, e.g. verbal descriptions of model features, goals, resources • Physical model, e.g. prototypes, mock-ups • Schematic model, e.g. graphs and flowcharts • Mathematical, e.g. equations and relations • All models are based on assumptions, e.g. market conditions, legal restrictions, physical performance limitations. Assumptions must be well-known and consistent
Information Systems Components • Inputs: raw data • May be physical, electronic or conceptual • May use a manual or automated process • Processing: conversion of inputs to outputs • May be comprised of computations, data storage, choosing alternatives • May be a manual or automated process • Outputs: information used to make decisions • May be delivered in paper form or electronically • Outputs of one system may be inputs to another system • Feedback/assessment: outputs used to improve system performance • Can flag for incorrect processing • Cue for managerial interventions • Supply estimates of future input values (forecasting)
Computer-Based IS Components • Hardware, computer equipment used for • input • processing • outputs • Software, computer programs that run on hardware: • systems software • applications software • Databases: specialized applications software designed to organize data and information on an organization’s operations • Infrastructure: equipment designed to link hardware across space: • telecommunications • networks • Internet • People: IS personnel and users • Procedures: rules for developing and using the IS
Business Information Systems • Transaction processing: automation of routine, labor-intensive processes • payroll • customer purchases • accounts payable Transaction processing systems have historically been mainframe-based, often run in batch, using older, less flexible technology. • E-commerce: commercial transactions conducted electronically • business-to-business • business-to-consumer • public sector-to-business • public sector-to-customer Value of E-commerce is estimated at $434 billion, with about 20% of total devoted to business-to-customer transactions
Business Information Systems (cont’d) • Management information systems: collection of people, procedures, software, hardware and databases designed to generate information for management decisions about organization strategy. MISs may comprise: • Marketing MIS • Financial management MIS • Operations MIS • Transaction processing systems • Decision support systems: an MIS intended to address specific, complex decision problems requiring interaction of managerial and machine expertise. Composed of: • Database • Models • User interface • Reporting
MIS Demo: Workforce Training Information System (Fall 1998) • Policy context • Increase in spending on local constuction • Need to remedy lack of minority participation in construction • Increased gov’t funding for organizations that can show positive results from job training programs • Desired features • Registration information on all program participants • Assignment of participants to training program classes • Recording personal and class outcomes • Implementation • Relational database application using Microsoft Access97 • Web pages describing project teams, problem and solution using Microsoft FrontPage98 (http://pirate.heinz.cmu.edu)
Information System Development • Analysis and Design • problem definition • justification of solution approach • system requirements • project team • conceptual application model • Implementation • Prototyping • Large-scale development • Testing • Deployment • Maintenance and Review • Evaluation of delivered product • Customer support • Upgrades
Careers in Information Systems/Information Technology • Operations • systems maintenance • LAN operations • data entry • Systems Development • systems analysis • hardware/software development • Support • data administration • Web development/maintenance • Interface • IS analysis in functional areas: engineering, planning and management • Participation in multi-disciplinary teams bridging policy and IS Heinz MSPPM/MAM IS/IT training is oriented towards interface and systems development careers
