Wondering about the Job Descriptions

In addition to all the ASIEs, there are a pile of Job Descriptions for AMC members and other National Appointees and committees. Interestingly, some of those appointed positions do not have matching ASIE that established them or that outline what the AMC wants those positions to be doing. They just exist, and someone, somewhere, wrote job descriptions for them.


So now I am wondering:

* Who wrote them?

* How were they approved (and by whom)?

* Are they considered directives of the AMC in the same way committee charges are?

* What is the procedure for reviewing and updating them?

* Does anyone ever stop to ask if we still need those positions?

* Who is responsible for writing new job descriptions?

* To whom do they get turned in?

* What is trump when a job description conflicts with text in a handbook?
