Here is a great post from Andrew Wien on quantifying the impact of mindfulness training in a business setting:
How to Reduce Stress, Increase Focus, and Improve Communication at Your Company
Andrew is extremely knowledgeable and has been developing his mindfulness curriculum over the last few years.
His corporate mindfulness sessions emphasize focused attention training, awareness, managing negativity bias, and stress management. He really helps you get at the underpinnings of what mindfulness is, how it works in your brain, and how it can help you.
He is the founder of The Dynamic Leadership Center.
