We report qualifed leads to sales using the RCA. Our success path is created such that we have an SLA off of our success path for our "suspects" which are marketing leads directly pushed to sales. They have 14 days to change the status of these leads. Setting up our success path in this manner makes it super easy to pull a report to see who has/hasn't moved from there.
You can then also pull coinciding SFDC reports for Sales Managers to have insight as to who has/hasn't moved along the success path, which we've found extremely helpful.
