Shrink the Pink Slice!

What’s the Pink Slice? The Pink Slice is a term used to describe what you don’t know you don’t know. In many aspects of Emergency Management Incident Command, there are things you know  – for example what the strategic, operational and tactical objectives should be  during a routine response to an incident – and there are of course things you know you don’t know (like whether the incident will escalate beyond your command and control). There are also things you don’t know what you don’t know – meaning you didn’t even have a clue there was a possibility of this (whatever “this” is) occurring or impacting your Incident Command.

The origins of this thought process is credited to former Secretary of Defense Donald Rumsfeld who, in a speech to NATO in 2002, stated:

As we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don’t know we don’t know.

The goals for this post are to have threads that provide good examples of how to shrink the Pink Slice in Emergency Management situations (it doesnt have to just be Response – could be any phase of the Disaster Cycle). We may start a new thread, add to existing ones ourselves, etc. Better knowledge and understanding – and the chance to shrink the Pink Slice a little more each time, is what we hope to achieve.
