Representation of automated tasks performed by a system

[Hudson Assis]

Hi everyone,

I'm creating a process flow and I have to represent some automated tasks performed by a system. My doubt is: Do I have to create a lane for the system and consider it like a process interface (image 2) or I should keep the system's tasks in the same lane of person 1 (the only process's interface)?

Image 1 - System represented by green tasks in the same line of Person 1

Image 2 - System represented by a lane with your tasks

Many thanks,

Hudson.
