What is information?

What are the characteristics of good information?

What is the difference between information technology and information systems?

How Can You Use the Five-Component Framework? Pearson Prentice Hall 20091-12Five components interact with each other to create a complete system

The Most Important Component YOUYou are part of every information system that you useYour quality of thinking is a large part of the quality of an information system

How Can You Use the Five-Component Framework?1-13Actors hardware and people take actionsInstructions software and procedures provide instructions for actorsBridges data bridges hardware/software and people/procedures

How Can You Use the Five-Component Framework?1-14

How Can You Use the Five-Component Framework?1-15High-Tech Versus Low Tech how do you tell the difference?

Low tech using an email programjust a small amount of work is being accomplished by a computer system.

High tech implementing a customer support systemlarge amount of work is being accomplished by the computer system rather than humans.

The determining factor is the amount of work that is moved from the human side to the computer side in Fig 1-3.How Can You Use the Five-Component Framework?1-16After this class, youll look at an information system and evaluate each component separately and then as a whole system.Hardware is often the easiest component to identify and evaluateIdentifying and evaluating the role of the people can be tricky, but leads to a great understanding.

What is Information?1-17before we really talk about Information SystemsInformation is:Knowledge derived from data.Data presented in a meaningful context.Data processed by summing, ordering, averaging, grouping, comparing, or other similar operations.A difference that makes a difference.ProcessingData vs. InformationDataraw factsno contextjust numbers and textInformationdata with contextprocessed datavalue-added to datasummarizedorganizedanalyzed0Data vs. InformationData: 51009Information:5/10/09$51,00951009

What some people consider information, others think of as raw data.

Context changes occur in information systems when the output of one system is input to another systemWhat is Information?1-24Information is SubjectiveData in a manufacturing system may be very important to that system. When its combined with data from other systems, it may lose its prominence in the larger context.Manufacturing ISFinancial ISSales ISRaw sales Demand ForecastRaw parts inventor Production Forecast

Characteristics of Good Information?1-26Accurate entering incorrect sales data creates false information.

Timely knowing that production doesnt have enough raw materials for next weeks schedule wont be useful information three weeks from now.

Relevant if your boss needs to know how many shipments were late last month, you shouldnt give him a list of all items that shipped.

Worth its cost is it cost worthy to map out the entire U.S. if you only need one state?

These are just a few characteristics that are important...Information Technology vs. Information Systems?1-27Because many people confuse the two terms, compare what each one consists of and how the two differ.

Information technology drives the development of new information systems.Information Systems include five componentsHardwareSoftwareDataProceduresPeople Information technology pertains to New Products New Methods Inventions StandardsInformation Technology vs. Information Systems?1-28Moores LawThe number of transistors per square inch on an integrated chip doubles every 18 months.

Dramatic Reduction in Price/Performance RatioRatio fallen dramatically for over 40 years and is estimated to continue to fall in accordance with Moores Law.
