Startup methodologies are structured approaches that guide entrepreneurs in developing and launching new businesses. These methodologies help startups validate their ideas, minimize risks, and efficiently allocate resources. Common frameworks include the Lean Startup, which emphasizes rapid prototyping and customer feedback, and the Business Model Canvas, which provides a visual tool for mapping out key business components. Another popular methodology is Agile, which focuses on iterative development and flexibility in response to changing market conditions. By adopting these methodologies, startups can enhance their chances of success and adapt more effectively to the dynamic business environment.
