U.S. ATLAS HL-LHC Upgrade Level 2 and Deputies-NSF only Management Mailing List

[Stephanie Majewski <smajewsk AT uoregon.edu>]

Hi Gustaaf,

Are you suggesting that we include some version of this in our slides (or should we upload it somewhere)? Or are you suggesting to just complete the template and have it ready for reference.

Thanks,

Stephanie

Hello L2 managers,

After our interactions with NSF for the most recent BCP and their
comments on recent variance reports, we believe it is important that you
prepare for the upcoming reviews by quantifying the impact of the
statements you made over the past year.  This includes the descriptions
in the COVID BCPs as well as statements in variance reports.

NSF will verify if everything is consistent.  Here's a relatively simple
example related to the LAr ADC development that will lead to questions
from NSF:

-significant COVID-induced delays were incurred because of the
pre-prototype radiation test delay (8 months) and now the prototype
foundry delay => ok
-there's also a statement that some parts of the chip are substantially
more complex and require more engineering

Since the latter is not in any BCP, we should see a corresponding cost
variance.  But here's what we see:

-in the May CPR, the combined 6.4.1 Columbia+Austin cost variance is
-$98k, looks as expected
-however, declared COVID actuals for 6.4.1.1 and .2 add up to $118k
So the net non-COVID cost variance is actually +$20k.

NSF is asking

a) that statements like "some parts of the chip are substantially more
complex and require more engineering" be quantified: how much more
engineering?  At what cost?

b) that ultimately things add up: since that extra engineering isn't in
the baseline, it's an extra cost.  But it's not reflected in the cost
variance.  Why?

Please go through each of your deliverables, list all the statements you
make and the variances at those times, and make sure you can explain all
the numbers.  I attach a template that tries to make this easier.  The
template may need adjustments...

You should probably complete this before the DR.

Best,

Gustaaf
