Problems / Challenges


Repeat Dispatches

Repeat dispatches costs service providers millions -- about 15% of their repair business



Problems Coming Inside the Home

Leading Problems Reported by Customers: Slow or intermittent Internet service “Faulty” modem but 80% of time modem replacement is unnecessary Random dropping of connection Why are They Difficult to Diagnose: Can’t determine where the problem exists Can’t measure compliance to field test procedures Inconsistent testing methods, tools and technical expertise

Slide 8

These problems are difficult to identify and repair. Unresolved, our field data shows they can lead to 10 – 15% of customer churn
