How do you keep track of agents who show my home, and buyers who will see my home?

We have an advanced CRM (CRM = "Customer Relationship Management") system - basically a large database, where we input all showings & customer views. However, it's much more than just a database. Here's how it works:

1. An agent shows your property. When they use their lockbox key to open the lockbox on your property, we get an alert on a website, telling us they've shown your property. Here's what that page looks like (click image to enlarge):
2. We input this data into our CRM system, so we have the name, phone number and email address of each agent & buyer who has seen your property. Here's what that looks like (click to enlarge):
3. We then call & email each agent for feedback. If you'd like, you can also upload any business cards that agents leave at your property by going to www.DROdio.com/showings . Either way, whether you do it, or we do it, the agent will get a request for feedback, and we'll be able to tell you how interested the buyer was, and if they weren't interested, why, so you know what you'd have to do to your property to get the buyer interested. And if multiple buyers point out the same issues with your property, then you know it's something you should change!
4. By having all interested parties integrated into this CRM system, we can quickly & easily let all of them know when there are changes to the status of your property. For example, when we get an offer, we can quickly tell all the other agents that we have an offer, to see if any of them have interested buyers. Or if you decide to change the price, we can quickly alert everyone of the price change. This makes easy work out of what is a very laborious process for most real estate agents (in fact, many don't even bother because they don't keep track of all the agents who have shown the property!)
