What is quality? Why do we need it? How can we improve it?

It's a vague term and people often mean different things with it. But we do know it's important. 

With over 100 million downloads on his open source project, Dennis "The Continuous Improver" Doomen is our go to guy. He not only explains what quality means and why we need it, but gives us tools to improve it. 

Enjoy!
