Information concepts1

Knowledge

Information

Data

Information Concepts

The body of guidelines and procedures used to select, organize, and manipulate data to make it suitable for a specific task.

A collection of facts organized in such a way that they have additional value beyond the value of facts themselves.

Raw facts


Information concepts2

Information Concepts

KNOWLEDGE

  • Knowing the value of tracking sales for future ordering. As the business accumulates more and more INFORMATION, KNOWLEDGE increases.

    INFORMATION

  • Total sales of every item for the day, week, month, and year, and season.

    DATA

  • Recorded sale of every item.


Data vs information

Data vs. Information

Applying knowledge

The collection of information

adds to all the more knowledge.


Data vs information1

Data vs. Information

DATA: A record of each hamburger sold during the week.

KNOWLEDGE: Not a lot of people like to eat hamburgers early in the morning. Should we open our hamburger stand at 10:30 am or wait until 11:00 am?

INFORMATION: The number of hamburgers sold from 10:30 am to 11:00 am on the average.

2 Hamburgers were sold during this half hour period, on the average.


Data vs information2

Data vs. Information

QUESTION: Would you open your hamburger stand at 10:30 am to sell 2 hamburgers?

ANSWER: Probably, no.


Data vs information3

Data vs. Information

Knowledge

--Air conditioner compressors get “tight” when

not used for long periods of time. This could blow

a fuse when the air-conditioners are first turned on.

Information (organized data)

--Track air-conditioner fuse sales daily, weekly,

monthly, yearly, seasonally.

--Track daily temperatures relative air-conditioner

fuse sales.

Data

--Record each air-conditioner fuse sold.

RESULT: On days when the outside temperature jumps

and air-conditioners are first turned on,

the demand for air-conditioner fuses jumps

32 times normal.

Question: What actions will management take?
