I have to do some brainstorming regarding an Approval Process solution, and would love any suggestions you have.  Here's the requirement.  

Two step approval process.  

• First Step:  Approved by one of the  Assitant Managers.  (30 different Assistant Managers that manage unique areas) 
• Second Step: Approved by Senior Manager

Challenge:  The submanagers are not salesforce users in Salesforce.  I know that approvers have to be users in SalesForce, however these managers will never be.  

I have to think outside the box, even if i totally remove the first step of the approval process and replace it with a field update, apex coding, or have to do some programming in microsoft Outlook.

 Thanks for your strategy thoguhts!
