Employee Reviews

Hello! 

I'm trying to create a template in Adobe Sign that will allow us to send a self-review to an employee, and performance review to the manager, then be approved by the department head. It seemed simple, but...The employee section needs to be signed after the manager provides their input, and the employee cannot see the managers until the review happens. 

Is there a way to:

1. Have the employee fill in their self-review

2. Manager then fill in the performance review

3. Review Happens

4. Both sign/comment

5. Dept head approve? 

Would this be done in a workflow? Would I have to create two different documents?
