What are "Joint Points" and why do they matter?

According to today's criteria, yes. Back in the day it used to be joint was the kiss of death because boards couldn't assess the value vs. "a real job". Promotion board precepts changed to "shall not be disadvantaged", which made it neutral. Now it's considered a pedigree item. And accordingly, the Army puts a thick Reg together about it to essentially remove some of the job reviewing officers do when looking at your record. Always important to ID the pedigree requirements early so you have time to do something about it. Here you have to be shrewd sometimes in dealing with the flesh peddler shop and get meaningful assignments to check that box. Be wary of stuff that happens to deflect you from getting your points in. Not having a full up pedigree makes it easy to toss you at the third crunch board wise.

To clarify, I'm deployed at a Joint Base with Navy, Air Force, Marines and even Coast Guard involved in our operations. During our RIP/TOA, they discussed "Joint Points" and the process to get them approved. Apparently you get so many points for each joint exercise, brief, etc. I've been in uniform over a decade and I've never heard of this before. Can someone spin me up on this?
