The term "information sharing" gained focus after the 9/11 Commission Hearings in reference to the fact that government organizations failed to share information that, if shared, could have thwarted the attacks. There is not a standard method across organizations in the emergency management sector to facilitate the need of better information sharing. Obstacles include: resistance to sharing, information classification/need to know, accessibility/portability of information, and mechanisms to support sharing and when.
In addition to sharing information across organizations, information must also be shared within an organization. This must be practiced in non-emergency states, so that expertise and knowledge is not siloed during emergencies.
