The Big QuestionsWhat is MIS?

What should you learn from this class?

How can you enjoy this class?

What is MISMIS—management information systems—is

the development and use of information systems that help businesses achieve their goals and objectives

Three key elements:Components of information systems Development and use of information systemsAchieving business goals and objectives

What is MISInformation Systems components

Hardware – desktops, laptops, PDAsSoftware – operating systems, application programsData – facts and figures entered into computersProcedures – how the other four components are

usedPeople – users, technologists, IS support

Development and Use of Information Systems

You mightSpecify the requirements of an information systemsManage development projects that use information

systems and technologyYou must

Use information systems effectively and responsibly.

The Core Purpose of allManagement information systemsHelps a business achieve goals and

objectivesIncrease sales / grow the businessIncrease efficiency / cut costsMake more moneyGain a competitive advantage

Think about the information systems around you and how they interact with each other. How do they affect your life and your job.

Every day you touch dozens of information systems.Does the information provided make a

difference?Do the systems and information impact your

personal life and your job?

Functional AreasEarly information system were designed to

help business in key functional areas.

Accounting (Transaction Management)Finance (Investment Management)Marketing (Advertizing and Sales

Management)

Human Resources (People Management)Operations (Production Management)

What 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 2009

1-11

Five 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 & Bridges

1-12

Actors – 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 program

just 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, you’ll 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?before we really talk about Information

Systems…Information 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

Information vs. Data is Subjective

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 system

What is Information?

1-24

Information is SubjectiveData in a manufacturing system may be very

important to that system. When it’s combined with data from other systems, it may lose its prominence in the larger context.

Financial IS

Characteristics of Good Information?

1-26

Accurate – entering incorrect sales data creates false information.

Timely – knowing that production doesn’t have enough raw materials for next week’s schedule won’t be useful information three weeks from now.

Relevant – if your boss needs to know how many shipments were late last month, you shouldn’t 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?

1-27

Because 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 Standards

Information Technology vs. Information Systems?

Moore’s Law“The 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 Moore’s Law.

Enabled developments such as:Laser printers, Graphical user interfaces, High-speed

communications, Cell phones, PDAs, Email, Internet
