With incessant progress of science and technology, the project-based development structure is becoming more and more popular for all types of industries, especially for the information technology industry, because old development process based on design requirement and production, customers had less interaction with design team, so the result and performance were imperfect; with indirect wasting of time and labor costs, design team only kept repeating design and produce processes, but still providing customers with unsatisfactory product, which led to project’s delaying. In the past, new product development performance could be affected by lack of communication within the team or with customers, inability to adapt to unexpected situations and other issues. "Agile development" is a new development process that was popular all over the world last few decades, but on the contrary, by now this term is only known by few people in Taiwan. Therefore, the primary goal of this study is to discuss agile development, requirement quality, team interaction and their relationship with new product development performance.
This study used SPSS statistical software to analyze data and selected sample from high-tech industries of Taiwan. During the research, this study has focused on factor analysis, reliability analysis, one way ANOVA and regression analysis. In period from March to April 2017, there were issued 130 questionnaires and eventually 126 were returned. The results of this study are as follows：
1.Agile Development has a significant positive influence on new product development performance.
2.Agile Development has a significant positive influence on requirement quality.
3.Requirement quality has a significant positive influence on new product development performance.
4.Agile Development has a significant positive influence on team interaction.
5.Team interaction has a significant positive influence on new product development performance.
