I've seen BDD in action (in this case using SpecFlow and Selenium in a .NET environment) for a small test project. I was very impressed - mainly due to the fact that the language used to specify the acceptance tests meant they engaged with the product owner much more easily.

I'm now keen to bring this into my current organisation. However I'm asked 'who else uses this?' and 'show me some case-studies'.

Unfortunately I cannot find any 'big names' (or even 'small names' for that matter!) of companies who are actively using BDD.

I have two questions really:

• Is BDD adopted by companies out there? Who are they?
• How can BDD be implemented in an agile .NET environment and are there any significant drawbacks to doing it?
