Extensible work order system and method

The invention discloses an extensible work order system and method. The extensible work order system comprises a work order design module, a work order server module, a process configuration module and an external system, the work order design module is used for providing a visual control configuration interface for a user, the user can configure a customizable form and a maintenance form in the interface according to the visual control, and the process configuration module is applied to configuration of a work order process; the work order server module is used for processing business logic of a starting node, an approval node, a processing node and an ending node in the process configuration module; and the external system can process the self-defined logic of the work order server module. The problem that a traditional work order system is difficult in business expansion in the work order circulation process is solved; decoupling of a platform system and a work order processing complex logic code is realiz
