No company would never even consider revealing the one secret that separates them from the competition. In enterprise software development the one and only differentiator is your source code. The power and integrity of your code is a reflection of the insight and intelligence your development teams bring to the marketplace. It is from this which all value, that your company creates, flows.
Exposing your source code is more than just handing the competition the keys to your car, it is handing them the means by which you pay for your car.
