In today’s society, Agile has gradually become the mainstream development mode in the industry, and more and more organizations have successfully realized agile transformation and made great achievements in improving research and development (R&D) efficiency and customer value. Agile has extended forward from the traditional pure R&D field to business agility and backward to the integration of DevOps development, operation, and maintenance. Therefore, our company also decided to develop agile transformation so that we could respond quickly and meet users’ needs, shorten the system construction cycle, avoid development waste caused by business changes, and ensure product delivery quality. Specifically, the Method 2.0 system and human resource 2.0 system are selected as pilot projects for agile iterative development. With users at the center of the initiative innovation and trial-and-error process, the systemic agile iteration is pushed forward with small quick runs, and the systemic construction mode is optimized with innovation. Two goals are expected. One is to achieve fast and high-quality project delivery through agile transformation, and the other is to summarize the transformation experience and sort out the system, standards, the process, and relevant supporting tools applicable to State Grid Agile projects. This paper introduces how to improve the software quality under the agile development mode from three aspects: working ideas, the practice process and methods, and the construction effect.
