ONE THING on Product Learning

Many Product skills you have to learn on the job, especially those focusing on leadership. I'm curious about the Product classes springing up around the world, and in some business schools. What is your view of these courses? Do they do a good job of training people? What skills do you wish more new Product people had? Discuss.
 
Masterclass
Speaking of learning, I am partial to a certain Masterclass: I'll be giving a Test-Driven Roadmap Masterclass in Boston, March 12-13. David J. Bland and I are teaming up to help you articulate a product roadmap and then systematically de-risk it though testing and validation. Early bird pricing before February 1.
