@Ravikumar

I think we had a similar question here from you [Unable to understand how to implement this things](https://community.temporal.io/t/unable-to-understand-how-to-implement-this-things/9100)

Are you starting those workflows from the same or different clients?  
What do you mean by interacting? signal/query?

Have you taken a look at the documentation and samples we shared in the post linked above?

@Ravikumar

Please, see this article regarding when to use child workflows [Purpose of Child Workflows?](https://community.temporal.io/t/purpose-of-child-workflows/652)

> should i consider HROPS is one workflow and IT is another workflow

Are they implemented by different teams?

> how should i run child workflows parallelly

I don’t have all the details for your use-case but sounds like a good reason to have a parent workflow written by the team HROPS and having the IT team exposing its implementation as a child workflow
