Components of an IS n Four major concepts –People, hardware, software, data and networks are the five basic resources of information systems –People resources include end users, IS specialists, hardware resources consist of machines and media, software resources include both programs and procedures, data resources can include data and knowledge bases, and networks include communications media and networks
Components of an IS n Four major concepts continued… –Data resources are transformed by information processing activities into a variety of information products for end users –Information processing consists of input, processing, output, storage, and control activities
Information System Resources
n People Resources –End Users – the people who use an information system or the information it produces. Ex: Accountants, salespeople, customers –IS Specialists – the people who develop and operate information systems based on the requirements of end users. Ex: programmers, analysts, system operators
Information System Resources n Hardware Resources –Machines, such as computers and other devices, and media, such as paper, disks –Computer Systems such as the personal computer (desktop), mainframe, or laptop –Computer peripherals such as keyboard, mouse, monitor, scanner, printer, disks
Information System Resources n Software Resources –Programs – sets of operating instructions that direct and control computer hardware –Procedures – sets of information processing instructions that people need
Information System Resources n Software Resources continued –System Software – such as operating system that supports the operations of a computer system. Ex. Windows 98 –Application Software – programs that direct processing for a particular use of computers by end users. Ex. Excel –Procedures – operating instructions for people who will use an IS. Ex. Instructions for filling out a form.
Information System Resources n Data Resources –Types of data Text data Image data Audio data –Data Storage Databases – hold processed and organized data Knowledge bases – hold knowledge in a variety of forms such as facts, rules, and case examples of successful business practices
Information System Resources n Data Resources continued… –Data Vs. Information Data – raw facts or observations, objective measurements of the characteristics of entities such as people, places, things and events Information – data that has been converted to a meaningful and useful context for specific end users.
Information System Resources n Data Resources continued… –Data is subjected to a value-added process 1.Its form is aggregated, manipulated and organized 2.Its content is analyzed and evaluated 3.It is placed in a proper context for a human user –Called data processing or information processing

Information System Activities n Input of Data Resources –Data about business transactions and other events must be captured and prepared for processing –Input typically takes the form of data entry activities such as recording and editing –End users typically enter data directly into a computer system or record it on some physical media such as a paper form
Information System Activities n Processing of Data into Information –Data is subjected to processing activities such as calculating, comparing, sorting, classifying and summarizing –This organizes, analyzes, and manipulated data, turning it into information –The quality of data stored in an information system must be maintained by a continual process of correcting and updating activities
Information System Activities n Output of Information Products –The goal of information systems is the production of appropriate information products for end users –Examples are messages, reports, forms and graphic images which may be provided by video displays, audio responses, paper products, and multimedia
Information System Activities n Information Quality –Information that is outdated, inaccurate, or hard to understand is not meaningful, useful, or valuable to end users –Information products should have characteristics, attributes, and qualities that make the information more valuable to the end users –Information has three dimensions of time, form, and content
Information System Activities n Information Quality continued..
n Storage of Data Resources –Data and information are retained in an organized manner for later use –Stored data is commonly organized into fields, records, files, and databases Information System Activities Name Field Name Field Payroll Record Payroll Record Payroll File Payroll File Personnel Database
Information System Activities n Control of System Performance –An IS should produce feedback about its input, processing, output, and usage activities –This feedback must be monitored and evaluated to determine if the system is meeting performance standards –Activities must be adjusted so that proper information products are produced for end users

Selection of DSS Development Tools Determine & contact key participants Elicit requirements / functionality Compose requirements into a RFP Distribute RFPs to potential vendors Collect and summarize RFP data Select RFP short list Set short list interviews and demos; references Select Vendor Negotiate contract
Complexity of the Software Selection Process 1.DSS information requirement and outputs are not completely known 2.Hundreds of software packages 3.Software packages evolve very rapidly 4.Frequent price changes 5.Several people involved
6.One language for several DSS? Tool requirements may change 7.Dozens of criteria, some intangible, some conflict 8.Technical, functional, end-user, and managerial issues 9.Published evaluations are subjective and superficial 10.Trade off between open and closed environments
Step 5. Implementation as Change n From development to production –technology acquisition –port to production platform –database conversion –system conversion strategy –user access, training, & ongoing support –documentation & maintenance n From implementation to institutionalization –existence does not guarantee use –use does not guarantee success
