Major telecommunications companies currently hold complex systems, with varying interdependencies and still remarkable reliability. The constant development and changes in their core, along with different types of users involved in the use of these systems, makes them extremely interesting. The maintenance, the service assurance and the positive evolution of this network depends on the deep understanding and control of these complex systems. This knowledge, which refers to different interactions between internal and exogenous systems, allows you, for instance, to control and increase the speed of problem solving, to correctly approach trouble tickets and to detect the root of the problems.

To address these problems, the deconstruction of an error safeguarding and fuzzy logic has been implemented, emphasizing the control, the precision and the planning of the systems behaviour. Statistics and Quality Control brought another perspective to approach these issues. The first results, obtained from field operations and with a direct influence on the user's experience, are the focus of this presentation.
