I'd like to hear from someone that has already cracked this nut, so to speak. We are redesigning our onboarding process, and we have a somewhat complex organization.

Should we be using one ticket with multiple tasks or multiple tickets?

If I have a customized form, can someone completing a master form trigger tasks or tickets to be generated?

Here's my example scenario:  

For example, HR goes through the hiring process and when they get the acceptance from the potential employee, they send a request to IT which starts the process. 

That ticket then has to go to the hiring manager in order to get the provisioning details (Laptop, User rights, Application A, B, and C, access to servers, email, etc).  In choosing those different options, requests need to go to the owners of those different functional areas in order to provision the items.

Thanks,

Adam
