The document discusses how open source software (OSS) can influence telecom customer experience. It describes collecting customer data through surveys, drive tests, monitoring applications and call center statistics to understand customer needs and expectations. This information is then analyzed using statistical modeling and metrics like Quality of Experience to identify any gaps between expected and delivered service quality. The results are used to provide network planners with reports and guidance to improve customer experience. Integrating OSS/BSS allows service providers to better align business and technical aspects by mapping offerings, products and network resources. This helps fulfill customer orders while managing service and product lifecycles.
