Product Truths:
Most products at scale don't fail from lack of effort, but from lack of clarity. Teams build the wrong things - for the wrong reasons - and nobody says so until its too late.
Direct, incisive and insightful - this is the book for product leaders who want to think more clearly and build more deliberately.
