A method for running a Self Organizing Network (SON) module in a communication network provides an open Application Programming Interface (API) for a SON framework and executes the SON module. The SON module accesses the functionality of the SON framework using the API. The SON module may be built by a developer other than a SON system provider and may be loaded into the SON framework by an operator other than a SON system provider. The SON module may be implemented as a state machine.
