Lab 1: Tutorial - Anna Creates Use Cases

This is a computer. A computer has a brain.

The computer’s brain is called a chip. A computer chip can think
some.

But a computer’s chip is not as smart as people.

Sometimes mom or dad tells you what to do.

Sometimes you think of things to do.

A computer cannot think of things to do without instructions. Instructions tell the computer what to do.

Ana knows how to create a special document.  

The special document includes a group of action words. The group of action words tells what actions a computer should perform. 

At work Ana is a Business Analyst.

Ana calls the group of action words a use case.

Ana writes a use case if she wants the computer to play a game. The use case looks like this: UC1. Play a Game.

Ana writes a use case if she wants the computer to play a movie. The use case looks like this: UC2. Play a movie.

Ana writes a use case if she wants the computer to play music. The use case looks like this: UC3. Play music.

After Ana writes the use cases she needs Lenny’s help. Lenny knows special code.

Lenny can use special code and his tool to turn use cases into software.  The computer can read software like you read books.

Software tells the computer what to do. Software can tell the computer to play a game.

Software can tell the computer to play a movie.

Software can tell the computer to play music.

Software can tell computers to do a lot of things. Just remember, Ana writes action words.

The action words are use cases. The use cases tell what a computer should do.

In this example, Ana gave the use cases to Lenny.
Lenny used a special tool to turn the use cases into software. 

The computer uses a computer chip to read the software. 

The software includes instructions the computer chip understands.
