%% @doc Systems Manager Incident Manager is an incident management console
%% designed to help users mitigate and recover from incidents affecting their
%% Amazon Web Services-hosted applications.
%%
%% An incident is any unplanned interruption or reduction in quality of
%% services.
%%
%% Incident Manager increases incident resolution by notifying responders of
%% impact, highlighting relevant troubleshooting data, and providing
%% collaboration tools to get services back up and running. To achieve the
%% primary goal of reducing the time-to-resolution of critical incidents,
%% Incident Manager automates response plans and enables responder team
%% escalation.
