Task decomposition strategy and granularity design in networked collaborative environment

Aiming at existing problems in traditional task decomposition method, a qualitative task decomposition strategy based on project-task-activity frame was proposed. The software metrics conception in software engineering was employed to construct the calculation formula for task cohesion. And a new method for task granularity design was put forward from the viewpoint of quantitative analysis. Furthermore, this method could precisely evaluate different task granularity design of complex product cooperation workflow in networked collaborative environment so as to realize flexible organization and effective management for different design processes. Finally, an example of automobile body collaborative conceptual design was provided to illustrate the effectiveness and feasibility of this method.
