The Lean Product Playbook

Olsen lays out a six step process for reaching product market fit. You identify the target customer, work out their underserved needs, define the value proposition, specify the minimum viable feature set, build the prototype, and test it with customers. The Product Market Fit Pyramid organises these into layers. Includes concrete method chapters on the Kano model, importance versus satisfaction analysis, user testing, and quantitative iteration once a product is live.
