Very Basic Nothing new,
Verified Purchase(What is this?)
This review is from: Lean UX: Applying Lean Principles to Improve User Experience (Kindle Edition)
If you have little or no understanding of basic UX, Lean and Agile principles then you should buy this book. Otherwise I wouldn't bother, theres nothing really new in here that you couldn't pick up by Googling for a few blog posts on the subject.
