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

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

A reminder for Tim and me (Andy is already done) that the VRs for May 
are due very soon.  Also, take note of Gustaaf's point that these VRs in 
particular will be discussed at the IPR in July, so we should make sure 
they are clear, etc.

Tim, let me know when you have submitted yours.

        Thanks,
                John

Hello all,

A reminder that the May VRs are due soon.  Keep in mind that the May 
working schedule is our basis for the July review, so it’s crucial to 
fully understand the variances.  This will have to go into your slides.

Many are already posted (thanks!), here are some comments:

-6.4.3 looks good, I have approved it

-6.5.4: I don’t understand this: any pre-rebaselining variance would 
have been zeroed out, and in fact there is no variance at Columbia.  I 
have unlocked this.

-6.6.3: the SV report looks fine, but CV is missing, so I have unlocked 
this.

-6.6.4: "The schedule variance of $866k is mostly due to delays in the 
schedule. We are set to enter full production now, so are hit with a 
variance of roughly $720k.” This basically says there is a schedule 
variance because there is a schedule variance.  Please say something 
about the actual source.  (I guess it’s purchase of comonents…)  I have 
unlocked this.

-6.6.5: looks good but you forgot to submit.  (BTW, I think you meant 
“remainder” rather than “reminder”)

-6.8 looks good and I have approved.
-6.8.3: nice to see a $100k positive variance this month.  I approved 
the text.

Best,

Gustaaf
