Within the product package “T-Home Entertain” the customers of Deutsche Telekom receive a broadband connection, which offers the opportunity to use these services via an IP-based connection. To ensure the availability and quality of this product and its components, a solution to monitor and evaluate, and appropriate means to deduce necessary measures for improvement are needed.

Within the project, an analysis and monitoring system with measurement points along the product chain in the field of IPTV products has been developed and implemented. As a prerequisite for the monitoring of the process and the measurement points respective operating numbers were defined, due to which qualitative improvements can be identified. The business intelligence software QlikView® was installed as a front-end and analytical tool for the metrics-driven end-to-end diagnosis of interferences at the customer’s product or at the systems.
The databases of all relevant source systems were integrated into a data mart via a multi-stage ETL process. In this process specific mechanisms to ensure the data quality and thus to guarantee significant results were constructed. At this point, QlikView was deployed again, as a monitoring solution for indicators to safeguard the quality of the data. At the same time, a metadata model for the management and analysis of quality and process information has been integrated. The data integration and data quality management architecture was implemented on the basis of Informatica PowerCenter and Informatica Data Quality. The data storage and the design of data marts were carried out with Oracle 11g Enterprise.
The realized measures allowed a complete end-to-end diagnosis of potential interferences of all systems and components, which are part of the production, through individual and mass analysis. With the evaluation of the diagnosis results the availability and quality of the product “T-Home Entertain” and its components can now be consistently monitored and possible deficiencies can be detected early. Thus, statements about existing vulnerabilities are possible and necessary measures can be initiated quickly and efficiently.
