RTFM

A common acronym in IT parlance.

And in other venues, like the State Department. Only there, slavish adherence to "the manual" leaves dead Americans in its wake.  At American Thinker:

Ms. Charlene Lamb from the State Department was identified before the House Oversight and Government Reform Committee as the person most directly responsible for the rejection of multiple requests by the diplomatic mission in Libya for additional security personnel.  Quoting from the Committee transcript, Congressman Issa, Chairman of the Committee, during questioning said to Ms. Lamb,
 
ISSA: "Now the problem I have is that the State Department is basically saying Mr. Nordstrom didn't do his job, he didn't make a formal request for justification, the Ambassador didn't do his job, he didn't do a good enough case, and that is what you are standing behind here today in addition to saying "Well, there were five people there, therefore." An embassy, a compound owned by us and serving like a consulate was in fact breached less than 60 days before, approximately 60 days before the murder of the ambassador in that facility.  Isn't that true?"  

LAMB: "Sir, we had the correct number of assets in Benghazi at the time of 9/11 for what had been agreed upon." 
 
Issa's time had expired.  There were no follow up questions and there have been no requests for clarification from other sources.  The statement made by Ms. Lamb is quoted in most reports of the hearing and then ignored, but it is possibly the most revealing comment made by Ms. Lamb.  She had the correct number of assets in Benghazi...
 
...too many in decision making positions are incapable of making decisions.  

But they have a manual they can follow regardless of circumstances.  CYA.
