Abstract:In the face of fierce competition market, product operators are often struggling with limited human resources, high costs, and iterative tasks that require high and numerous times. In order to maintain the user satisfaction and reduce the iterative pressure of product operators, the article designed an iterative development model for network collaborative innovation products. Firstly, the blockchain technology is used to build a network collaborative innovation cloud platform to realize functions such as information sharing and public participation tasks. Then form a network collaborative innovation team to achieve fast and high-quality innovation tasks through this model. Finally, the specific path of the network collaborative innovation iterative development mode is designed, including the implementation path of further fast response in this path. The iterative path established by the article can be used to help enterprises improve the iterative speed and iterative quality in iterative innovation.
