Important questions1-10What is the five-component framework and why is it important?

What is information?

What are the characteristics of good information?

What is the difference between information technology and information systems?

Five-Component Framework? Pearson Prentice Hall 20091-11Five components interact with each other to create a complete information system

Why is this importantIn a business you are part of the information systemMost people think of IS as hardware and software onlyData, Procedures and People are the more crucial components

Actors, Instructions & Bridges1-12Actors hardware and people take actionsInstructions software and procedures provide instructions for actorsBridges data bridges hardware/software and people/procedures

Automation & Resistance to Change

High Tech vs. Low TechLow 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.

How Can You Use the Five-Component Framework?After 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 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.
