Detection is impossible despite spending budgets on advanced monitoring, and while personnel are continuously hired, reporting systems and internal regulations remain inadequate. This is part of a lecture for ongoing research and guidance aimed at resolving the persistent customer dissatisfaction, inconvenience, and total loss of service trust caused by these incomprehensible management systems.
