@Ravikumar

I think we had a similar question here from you Unable to understand how to implement this things

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?

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

github.com

temporalio/samples-python/blob/main/hello/hello_child_workflow.py

import asyncio
from dataclasses import dataclass

from temporalio import workflow
from temporalio.client import Client
from temporalio.worker import Worker


@dataclass
class ComposeGreetingInput:
    greeting: str
    name: str


@workflow.defn
class ComposeGreetingWorkflow:
    @workflow.run
    async def run(self, input: ComposeGreetingInput) -> str:
        return f"{input.greeting}, {input.name}!"

yes HROPS maintained by one team and IT maintained by one team

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
