U.S. ATLAS HL-LHC Upgrade LAr Level 2 and Level 3 Managers Mailing List

[John Parsons <parsons AT nevis.columbia.edu>]

Hi all,

	Thanks to everyone for the help with today's scrubbing of the risks in 
the LAr DOE scope. I give below my notes.  Comments/corrections are welcome.

                John


General remarks (applicable to all risks)
------------------------------------------
	- revisit and improve Comments fields to more quantitatively address 
cost and schedule ranges for impact
	- many (most) probability categories need to be cleaned up, in part due 
to the ongoing transition from prob. to categories for the DOE scope


PA/Shaper
----------

RD-06-04-05-004 (Analog Performance Issues)
                - Low
                - increase HI cost impact to $500k

RD-06-04-05-005 (ASIC Yield)
                - Low

RD-06-04-05-006 (External Dependency)
                - Very Low

RD-06-04-05-007 (Loss of key personnel)
                - Low

RD-06-04-05-008 (Increased complexity)
                - Moderate Low
		- rewrite to make risk more broad, ie. to cover increased complexity 
in entire development, from current prototyping through testing

RD-06-04-05-009 (Shipping loss)
                - Very Low
                - typo. - change Ensure to Insure



System Integration
RD-06-04-04-001 (FE crate system integration delayed)
		- split into 2 risks, one on "External deliverables delayed or not 
meeting specifications" and the other on "Increased complexity in FE 
system integration".  the second would be similar to the current 
RD-06-04-04-004 (Increased Complexity for BE integration)
		- we did not specify, but I would propose Moderate Low for both of the 
FE risks

RD-06-04-04-002 (BE crate system integration delayed)
		- as above for FE, have one risk just for "External deliverables 
delayed or not meeting specifications", and absorb the rest into the 
existing RD-06-04-04-004
		- again we did not specify, but I would again propose Moderate Low for 
both of the BE risks  (we could try argue the BE is simpler, with fewer 
deliverables etc., and so perhaps one or more could be Low.  However it 
is not so clear to me how convincing that would be.)

RD-06-04-04-003 (Loss of key personnel)
                - Low
		- we agreed we should focus just on BNL personnel here, as is indeed 
currently done
		- we also agreed we would NOT add an explicit risk for "External 
dependencies"

RD-06-04-04-004 (Increased complexity in BE integration)
                - see comments above
                - consider whether HI cost impact of $120k is sufficient
		- wording: change "increase one or two engineering efforts" to 
"increase engineering effort by 1-2 FTE"
