Create Sales Process and Validate Opportunities
Create a sales process with the required stages and name it RB Robotics Sales Process. Create a record type named RB Robotics Process RT. Add a field to the opportunity page layout as described in the business requirements and create the appropriate validation rule for high-value opportunities.

Hey, nice work on the setup records! Now let’s talk about our sales process. Most of the stages we use are already in Salesforce, but one of the stages we track doesn’t come standard so it would be great if you’d add it. These are the stages we use:  Prospecting, Qualification, Proposal/Price Quote, Negotiation/Review, Awaiting Approval, Closed Won, and Closed Lost. We want all our reps to follow the same process, so everyone should see those stages for every opportunity. 
Oh, and the biggest deals--anything over $100K--have to be approved before they can close. We should have a way to show on the record that the deal is approved--maybe you can add an “Approved” checkbox to the opportunity. Obviously the sales reps shouldn’t be able to check that box. Only system administrators like you and sales managers should be able to check it. By the way, all of us sales managers here have the Custom: Sales Profile in Salesforce.

   1. Approved (Checkbox) Defaulted FALSE

      ) 
      )

      
      2. High_Value_Opportunity_Validation

          IsClosed = TRUE,
          Amount  > 100000,
          Approved__c  <> TRUE
