1. As a user case scenario, I choose to require supporting the Amazon Alexa voice assistant to allow its users to alter smart device states by voice command. To achieve this functionality, I define new logical, process and deployment view to show how the Alexa API is integrated in the architecture.

## Process View

Use case: a user alters manually the state of device 'D' via Alexa voice command,
|
||||
and the device updates accordingly. Device 'D' is not part of any defined trigger.

||||

||||
