MVU, or Minimum Viable Unit, refers to the smallest version of a product that can be released to gather feedback from users. It focuses on delivering just enough features to satisfy early adopters while allowing developers to learn about user needs and preferences. This approach helps in minimizing risks and costs during the initial stages of product development. The concept of MVU is often used in startups and agile development methodologies. By prioritizing essential features, teams can iterate quickly based on real user input, leading to more effective and user-centered products. This strategy ultimately aims to enhance the chances of success in the market.
