ment interface that can make the monitoring pro- cess much easier for professionals at the NOC. This can reduce the fulfill- ment and service time and provide more consistency in information. Cost reduction is also achieved by saving on the expense in training personals with various management interfaces. Management solutions that can hide the network complexity and provide abstract information that would be easier for the technical and customer support professionals to work with. Complex services would impose more OSS/BSS Functions limitations on the technical desk in identifying the network issue. This would affect the problem handling and service fulfillment time. Filtering the most relevant events for the issue raised by the customer would be a challenge if sufficient event abstraction is not already in place. Auto recovering and self-managing network elements can reduce the work of the support professionals and fix issues of the customer without having to call up the support desk. With an increase in network complexity, the cost of maintenance and time to fix issues will increase. Auto recovery mech- anism and presence of self-managing network are key functionalities in a well-managed network Standard based development and well-defined contracts for interaction should be followed by the service developer to ensure interoperability and ease of integration. The issues that originate in a multisupplier/partner environment with acquisitions/mergers can only be addressed using standardization. Transformation of legacy application is also a strategy followed by many ser- vice developers. Since legacy solutions are functionality rich, many service developers don't opt for new SOA-based solutions, rather they transform their legacy solution in stages to an SOA-based framework. COTS software and hardware developed with holistic telecom vision should be used by service developers in the solutions they offer to service provider. Off the shelf implementations will reduce cost and integration time. The challenge is to en
