The connection between disaster planning, capability and capacity are essential, but often overlooked. In collaboration with end-users (Emergency Management Victoria and Home Affairs), the research team has developed a capability maturity assessment tool, designed for use by jurisdictions and organisations to assess the current maturity of their capabilities utilising a series of criteria. The tool is Excel-based and easy to tailor to specific contexts. Functions to support summary reporting have been incorporated. The tool can be utilised on a longitudinal basis to assist jurisdictions and organisations to measure and report on their preparedness.
