What is your business model?

I've been reading a lot about the business model canvas and it looks like a very interesting way to test a number of business models and ensure you've really thought about 9 aspects that can drive business success.  If you are not familiar with the business model canvas found a great video series (6 short videos) that show you how to use the business model canvas. The video series “From Idea to Business” teaches entrepreneurs how to design and test business models that help their ideas have a better chance of succeeding.

If you've never seen a business model canvas, there are many version online, but here is a quick view of one:

The notion is that unlike a business plan, this is a living document that you test and change until you settle on the best model.  A short description of each of the elements of the business model canvass:

1. Customer Segments: Who are the customers? What do they think? See? Feel? Do?
   
2. Value Propositions: What’s compelling about the proposition? Why do customers buy, use?
   
3. Channels: How are these propositions promoted, sold and delivered? Why? Is it working?
   
4. Customer Relationships: How do you interact with the customer through their ‘journey’?
   
5. Revenue Streams: How does the business earn revenue from the value propositions?
   
6. Key Activities: What uniquely strategic things does the business do to deliver its proposition?
   
7. Key Resources: What unique strategic assets must the business have to compete?
   
8. Key Partnerships: What can the company not do so it can focus on its Key Activities?
   
9. Cost Structure: What are the business’ major cost drivers? How are they linked to revenue?
   

Anyone do this and want to share theirs for feedback?
