Features

Features represent the interactive system functionalities and associated UI as well as interaction.

ARROWS recommends paying particular attention to the UI by considering it separately as a specific aspect of each functionality.

In addition, ARROWS suggests considering the interactive system as a whole through a global feature named similarly as the system. 

In the specific case of Lyric, examples of features include: the automatic temperature control by the system (‘Geofencing’) and the manual temperature setting by the user; the global feature taking the system name is also represented.
