IS Chapter 1 Notes, What is MIS?

Hardware and People

2 Actors in the 5 Component Framework

Strategies, information systems, management and use

3 Key Elements of MIS (flipped)

Hardware, Software, Data, Procedures, People

5 component framework (flipped)

System

A group of components that interact to achieve some purpose.

Characteristics of Data

Accurate, Timely, Relevant, Barely Sufficient, Worth its Cost

IS

An assembly of hardware, software, data, procedures and people that produces information.

Timely (characteristics of data)

Available in time for its intended use.

Relevant (characteristics of data)

Both to the context and subject.

Accurate, Timely, Relevant, Barely Sufficient, Worth its Cost

Characteristics of Data (flipped)

Actors act upon other

Components to make things happen, and are the hardware and people.

Hardware and Software

Computer Side

Bridge in the 5 Component Framework

Data

Worth Its Cost (characteristics of data)

Data is not free, and there is always a cost.

Automation moves work from humer to computer side which increases

Degree of difficulty of change.

The characteristics of data help us

Determine the quality of data, and include it being accurate, timely, relevant, barely sufficient, worth its cost.

Data needs to be sufficient for the purpose

For which it is generated but just barely, not more.

Accurate (characteristics of data)

Good information is derived from accurate, correct, and complete data.

5 Component Framework

Hardware, Software, Data, Procedures, People

Procedures and People

Human Side

Automation moves work from

Human side to computer side on the 5 component framework.

Cannot be purchased

IS

Can be purchased

IT

Are you willing to publish your behavior to the world?

If not, then according to categorical inmperative, your behavior is unethical.

Categorical Imperative comes fromt he philosopher

Immanuel Kant, and states that one should behave only in a way that one would want the behavior to be a universal law.

Produce correct charts and insights because what you do

Impacts decision makers.

As we move back from left to right to update automation, procedures, and process, the degree of difficulty

Increases because working with people and procedures are full of uncertaintees and very subjective.

IS Stands For

Information Systems, and is an assembly of hardware, software, data, procedures and people that produces information.

IT Stands for

Information tech, and is the products, methods, inventions, and standards used for the purpose of providing information.

Processed Data

Information, and it provides value to its users.

Software and Procedures

Instructions

Every one of the 5 component framework (hardware, software, data, procedures, people)

Interacts with oene another to achieve its strategies or objectives.

From right to left is from human side to computer side and we're

Introducing automation into the 5 component framework.

From right to left in the 5 component framework

Is from human side to computer side.

Data by itself

Is worthless.

3 Key Elements to MIS

Management and use, information systems, strategies.

Goal of MIS

Managing Is to achieve business strategies.

Sometimes we have to update automation, update procedures and processes so we have to

Move back from left to right.

Working with computers are very

Objective and are well organized.

Categorical Imperative

One should behave only in a way that one would want the behavior to be a universl law.

IT doesn't have

People and procedurs.

What makes IT become an IS

Procedures and people.

Information

Processed data to provide value to its users.

Practice professional responsibility to

Produce correct charts and insights.

Key thing to determine value of data is

Quality

Data

Recorded facts or figures

IS is an assembly of

Software, data, procedures, and people. This all produces information.

Information is processed by

Summing, ordering, averaging, comparing, etc.

Just Barely Sufficient (characteristics of data)

Supports its purpose without any extra.

Data connects human side with

The computer side.

Computer Side of 5 Component Framework is on

The left side

IT

The products, methods, inventions, and standards used for the purpose of providing information.

Human Side of 5 Component Framework is on

The right side

If data is not timely

Then data acquired after decision is made useless.

We're bombarded with too much data, and we want

Toa void irrelevant data by being just barely sufficient.

We want to aovid irrelevant data because

We're bombarded with too much of it.

When considering the cost of data and its value, ask

What's the value, what's the cost, is it worth it.

What's teh cost, is it worth it, what's the value

When considering the cost of data and its value, ask (different order)

Most important component in 5 component model

YOU!

Information is value that

You add to the information systems.

Your cognitive skills determine the quality of

Your thinking, ability to conceive information from data, thus making you the most important component in 5 component model.
