Hey Harold: Nice post. Deming and Senge were in sync on many things. Deming's quality approach was built on a systems view of an organization, but his view was based more on continuous improvement of workflow, whereas Senge looked at deeper system dynamics at work and long term (delayed) impacts of current decisions (like Argyris). Learning through observation of the results of actions and reflection were at the core of both. You mentioned you hadn't read much Deming (it's pretty dry) but if you want a nice overview from a follower that articulated the approach nicely try Brian Joiners fourth generation management, which i mentioned in this post a while ago. https://performancexdesign.wordpress.com/2009/06/30/10-strategies-for-integrating-learning-and-work-part-3/ Tom
