Vendors that don't talk
What you have: CAD, mobile, mapping and alerting from four companies, and the seams break at 3 a.m. — when each vendor is certain the fault is with one of the others.
What we do: the console, the mobile terminal, the mapping, the station alerting and the paging are one product from one company, sharing one data model. There is no integration between them to go wrong, because there is no integration between them.
