I've been working on a pricing project using a methodology largely influenced by Nagle's work. The premise is that it's possible to learn what customers value before pricing something and for the price to be optimized around customer value, and perceived value. It feels much more promising than other pricing projects I've been involved with. This podcast gives an overview of some of the thinking here: https://impactpricing.com/podcast/ep46-alan-albert-why-much-...
that nagle book was taught in my MBA pricing class. small but surprisingly dense and thorough. there's a lot more to pricing than just value pricing vs. cost-plus.
