CMAT Prototype Development Bible

Asked in CMAT: 2024, 20252026 edition

A prototype turns an idea into something customers can test. This chapter explains prototypes, the minimum viable product (MVP) and the lean start-up approach of build, measure, learn. It also covers Everett Rogers' Diffusion of Innovation theory — how a new product spreads through innovators, early adopters, early majority, late majority and laggards. CMAT has asked both the MVP idea and the Rogers theory directly, so learn the adopter categories in order and the core lean start-up statements.
