The "lean startup methodology" emphasizes iterative development in product creation through building, measuring, and learning. This approach advocates for developing a minimum viable product (MVP) that incorporates essential features to satisfy early adopters. By quickly launching the MVP, startups can gather user feedback to refine and enhance the product continuously. This reduces the risk of substantial investments in untested ideas, promoting agility in adapting to market demands. Ultimately, the lean startup methodology aims to minimize waste, optimize resources, and foster innovation through constant validation and improvement based on real user experiences.
