An example: a coffee maker

In the following example the processes of a basic coffee maker are captured in a simple execution graph.

You can recognize the following process steps:

• A boiler producing hot water and
• a module that uses the hot water and coffee to make a good cup of coffee for you.

Now, we want to extend the machine with some nice features:

• A coffee grinder and
• a dishwasher that cleans your dirty cup with hot water before using it.

The execution graph of our luxurious coffee maker will look like this:

Analyzing the latter graph shows:

• Hot water is used for the dishwasher and for making coffee.
• Multiple tasks can run in parallel.
• The basic as well as the luxurious pipeline are captured in one single execution graph.
