Achieve sequential approval workflow-FIM 2010 R2

Hi guys,

In my set up, it is required that when users request access rights to different applications, the request should follow a given hierarchy. That is, the manager cannot approve if a user's supervisor has not approved. Similarly, notification of the approval should be sent to the next approver whenever the request gets approved.

I have tried to achieve this with FIM's workflow designer to no avail as any of the approvers can approve the request at no proper order.

1. How can I achieve the sequential order of approval?
2. How do I achieve notification to the next approver so they can look at the request and act on it?

Kindly assist.

Regards,

Phina
