1. Ahmet opened the app and saw the interface for creating goals as part of the app while scrolling down.
2. He directly clicked it and set some and he saw pre-defined waste production types in the screen.
3. He clicked and selected plastic to keep track of his plastic production.
4. He entered the values for his waste production into the system via just putting the numbers.

Terminating Situation:

• Ahmet successfully created his goal and put waste logs to it. The system takes care of his data in database.
