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.
