tomer. Optimization of energy usage is another key factor looked into by many telecom companies. The green initiatives in companies have added stress to optimize energy usage. Energy- efficient and sustainable communication can be achieved through optimal network design, site optimization, and the right choice of energy sources. Maximizing resource utilization and implementing scalable solutions to meet the capacity needs of Telco is also an activity under optimization. By optimizing the network, operators can get the most out of their existing investment. Optimizing network performance ensures capacity being used in the most profitable way. Efficient use of energy will help in securing the supply. 14. Data integrity management: When multiple OSS solution interoperates there can be inconsistencies in data that can lead to inaccurate computations and reports. Data integrity deals with insuring that data spread across OSS is consistent and accurate. With real-time service and network provisioning, integrity of data is a key concern. There are applications that handle end-to- end data integrity across solutions and data correction in specific modules like inventory reconciliation for inventory management based on resource discovery. Management Applications Data integrity management application does integrity checks to fix revenue leakage and reduce access cost. In some cases, a database cleanup is also performed as part of data integrity management. These applications can improve tracking of assets and reduce the number of provisioning failures. The basic operation of a data integrity management solution is to identify discrepancy and do synchronization of data. 15. Sales force automation (SFA): This is a solution that automates the business tasks of sales. The SFA gives the sales team the ability to access and man- age critical sales information. As sales involves frequent traveling, it is quite common to have sales force applications accessible through a PDA or laptop. In such scenarios, synchronization for sharin
