This diagram shows abstraction by focusing only on the main steps a user cares about when using a coffee machine. It starts with the user wanting coffee, then putting in a coffee pod, pressing the start button, waiting, and finally taking the coffee. The complex inner details like heating water, pressure control, or pod piercing are hidden because they are not important to the user at this level.

Each step is shown as a simple box with arrows showing the flow from start to end. This helps understand the process without getting lost in technical details.
