The invention relates to a development mode implementation method for solving traditional software development pain points in the field of software business requirement development. One step of processing is executed between transition sections of traditional requirement document determination and actual encoding development. Processing includes the following steps that firstly, a requirement document is split and refined so as to be converted into business modules and business lines; secondly, a client recognizable name is customized for each business line in each module and used for interaction positioning; thirdly, the business lines are divided into business points by means of a traditional process thought, and standard key value structures and corresponding key value content of input data and output data are set in advance according to each business point on the corresponding business line; fourthly, an actual configuration file is generated according to the relationship between the business modules, the business lines and the business points, and the configuration serves as the basis of business logical flow writing of development personnel. The development mode is special for solving the problems that in software development, high coupling occurs, development difficulty cannot be balanced, and development personnel cannot isolate barrier-free parallel development.
