How do GIS-based network analysis methods support business continuity planning?

• A. They model critical pathways (supply routes, power, communication), identify single points of failure, optimize rerouting, and evaluate redundancy under hazard scenarios.
• B. They only map existing roads and have no application to continuity planning.
• C. They replace the need for any contingency planning.
• D. They focus solely on demographic data.

Answer: (A)

GIS-based network analysis focuses on how the pieces of a system connect and how disruptions ripple through a network. In business continuity planning, this means building models of critical pathways such as supply routes, power and communication networks, and then using network analysis to locate single points of failure, test alternative routes, and evaluate redundancy under hazard scenarios. This approach lets you quantify resilience, identify where to strengthen infrastructure or establish backups, and simulate different disaster events to see how quickly operations can recover. Simply mapping existing roads misses how networks actually function under disruption, while replacing contingency planning with analysis isn’t correct, and focusing only on demographic data doesn’t address the connectivity and failover issues central to continuity planning.
