The invention provides a method for building a software production line platform based on Test Director, Harvest or Subversion, which is characterized in that: by combing the information standards, information flow and information dependency relationship during the process of software research and development; then general defects, modification and configuration management rules (such as flows, tables, fields, roles, authority and protocols) are formulated; unified bases for quality measurement and statistical analysis are established, and a set of measurement models for product quality and process quality is formed. Furthermore, an assistant software research and development synergic management system is also provided for fulfilling support; the operations of service linkage connection, rule mapping and information synchronization are performed for Test Director, Harvest or Subversion. Therefore, the invention has the advantages that: the multi-dimensional data acquisition for demand management, configuration management, alteration management, release management, project management and defect management can be completed, and a software enterprise asset library with a full life cycle is thus formed.
