My tiny little things

Just got a case about the military manufacturer.
Then i found a problem reading the word of 'hot wash'.
It's should be easy. Hot Wash. Hmmmm, using hot water to wash?
Well, i don't understand at all. Why is it connected?
I look it up. Here is the definition: Quite interesting!

------------------
A hotwash is a military and government term used to describe
the "after-action" discussions and evaluations of an agency's
(or multiple agencies') performance following an exercise,
training session, or major event, such as Hurricane Katrina.

The main purpose of a "hotwash" session is to identify strengths
and weaknesses of the response to a given event, which then leads
to another governmental phase known as "lessons learned," which
is intended to guide future response direction in order to avoid
repeating errors made in the past. A "hotwash" normally includes
all the parties that participated in the exercise or response activities.
These events are used to create the After Action Review.

Hotwash is a term picked up in recent years by the Emergency Preparedness
Community (likely as a result of Homeland Security and other government agencies'
involvement in disaster planning). It serves as the term for "after disaster briefings"
for all parties and entities involved to analyze what worked well; what needs improvement;
what person or agency needs to be responsible for said improvements; and the assignments and
timelines for the noted corrective and proactive improvements to be in place.
