Turning a product idea into a business involves several key steps. First, entrepreneurs need to develop a comprehensive business plan outlining their vision, target market, marketing strategies, and financial projections. Securing funding is often essential, whether through venture capital, crowdfunding, or personal savings. Building a prototype and testing it with a focus group can provide valuable insights and help refine the product. Finally, launching the product with a well-thought-out marketing campaign and continuously gathering customer feedback ensures ongoing improvements and success.
