nd working on a feedback loop between tech- nology neutral and technology specific implementation is a key activity that will help in enhancing the TNA. Software vendors need to make implementations based on the guidelines of holistic telecom vision and ensure that seamless information flows happen between different blocks to make final deployment a success with minimal faults. Prosspero is an activity group in TMF that is aimed at providing "ready- to-go" standards. Based on the standards recommended, vendors par- ticipating in this activity group create solution packages having reference code, guides, and test information. The implementers are the major con- tributors for this activity of creating solutions that will help companies to easily adopt the standards. Telecom application map (TAM) of TMF is an application map in tele- com space similar to the eTOM process map. The intent of an applica- tion map is to identify the areas in telecom space where applications are developed to meet specific requirements in resource, service, and business management. The implementation provider needs to ensure that TAM is Fundamentals of EMS, NMS and OSS/BSS defined to the lowest level of granularity process to make it beneficial for adoption. The development of procurable NGOSS contacts based on TAM also needs to be driven by the implementation provider. The implementation of a contract library including strategy for developing contract registry and repository vests on the implementation provider. In addition to solutions based on standards done as part of Prosspero, work should also go into development of tools that will aid the lifecycle, methodologies, interfaces, models, and maps defined by TMF. Operations /deployment team dealing with the deployment block The operations center should be implementing component-based man- agement that uses the capabilities provided by NGOSS system manage- ment architecture and reference implementations. Another activity of the operations center is to do business and service performance
