Enhancing Resilience, Reducing Damage, and Expediting Recovery to Mitigate Covid-19 Damages

Background:
We as a society, within the boundaries of the United States and its territories, are addressing a faceless global threat that we have come to know as the coronavirus or COVID-19. It attacks at the heart and soul of the nation and requires a multifaceted approach with a host of parties: federal government, state governments, municipalities, private sector, and non-governmental organizations as well.
With one of the most recent threats to our homeland security let alone the world, COVID-19 pandemic has stretched the limits of information sharing, collaboration, and coordination among the private sector (i.e. pharmaceutical industry, medical community); federal/state/local governments and agencies (i.e., Food & Drug Administration, Center for Disease Control & Prevention) and non-government organizations (NGOs). We have seen a divide in the Congress as to who is in charge and who is to blame. In the end, those that suffer the most is the America public. During times of a national emergency such as this, we must come together as a nation like after 9/11 and protect our citizenry at all costs and place politics aside.
The U.S. Department of Homeland Security (DHS) has issued recommendations for jurisdictions seeking to improve collaboration with their private sector agency counterparts. The initial collaboration focused on terrorism; however, can be applied to the pandemic or any national threat.
Question:
One of the readings for this week highlighted ways to improve collaboration with the public and private sectors, of the four recommendations provided, which one recommendation is the most beneficial for collaboration between the entities and why?
