Cross-Organization Workflow Research of Agile Telecom on Positive Feedback

In order to promote the core competitive power in telecom operating enterprises that face market fine operations, this article compares ECTA mode (Extension Case Transmission Mode) and LCA mode (Loosen Couple Mode). By comparing LCA mode with ECTA mode, we can find out the conditions, in which these two modes are appropriate. Besides, we can keep the semantics of the public flow mode and do our best to modernize the workflow by improving the task complexity, information transparency and operating controllability of LCA mode through a positive feedback system and by improving ECTA mode through a Petri net system.
