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

["Meyer, Chris" <cjmey AT iu.edu>]

Dear NSF L2s and Deputy L2s,

In preparation for the NSF re-baseline review, we will hold our quarterly NSF risk workshop during the CCB meeting on Tuesday, January 31. We will cover all systems in one meeting (~10 min per subsystem) and the agenda will be circulated soon.

As usual, please prepare slides covering:

• Changes in risks since the last risk review (especially those that can be retired);
• Updated task affected (to make sure it remains in the future);

• In particular, if you list multiple tasks affected include a clear description of how to treat this in the simulation. I.e., the risk should hit both tasks listed simultaneously (rare), or a chain of tasks is listed as a reminder but only the first should be considered in the simulation;

Update comments to clearly describe how the cost/duration uncertainties are arrived at;Potential changes to risks before the upcoming review, e.g.:

• changes to probability/impact of existing risks due to upcoming technical reviews;
• existing risks that could be realized or that need to be watched carefully;
• risks that might be retired.

The current risk register in docDB is v75, and the supply chain risk register is v7:

Please look over both in preparation for the workshop. After the workshop, please send Chris an updated version of the excel spreadsheet with your changes highlighted.

Any issues, please let us know.
