What problems can appear when systems are designed in isolation?

Systems designed in isolation can compete for rack space, network capacity, cable routes, power and access arrangements. They may also duplicate infrastructure or leave gaps where each supplier assumes another party is responsible.

Installing each system in isolation can lead to duplicated cabling, unsuitable rack space, poor network capacity, conflicting access arrangements and unclear responsibility when faults cross system boundaries. A useful assessment maps the people, spaces, devices, network paths, security requirements, call flows, access points, display needs and future changes that may affect more than one system.
