Create Invoice Approvals as First Responder Wins

Content

Create Invoice Approvals for some of the departments in Our organization as follows:

For Department 156:
1st approver - Person 1
2nd Approver - Both person 2 & Person 3 (First Responder Wins)
3rd Approver - Person 3

For all the other Departments:
if the amount is less than 200000 then route to Person 1
if the amount is greater than 200000 then route to Person 2

 

Does any one know a way to achieve this?
