@Mike: I’m fine with the language “to reduce risk” (or “to significantly reduce risk”).

 

@Gustaaf: A comment about the float for 6.8.1. Technically there are 2 floats within this L3 - one for FOX++ and one for fFOX. You are quoting the correct float for FOX++, but the float for fFOX is currently 132 days in the RLS after BCP-1057. I think it would be more appropriate to quote this float, since it is the later deliverable. We need to update the need-by date for the fFOX for the April Review - it is now later by over a year in the international schedule. This is on slide 19 of my L2 talk.

Hi Tom,

I see in the scope contingency #7 (chamber batch 8) has a decision date of Jan-23 (in the past!). Maybe it is still a viable option, but then the date needs to be updated.

Hi Gustaaf, John, Stephanie,

 

In scope opportunity I see below – my concern is with the language for all three is that “to ensure project success” sure sounds like a red flag after we told them we can deliver 90% certainty!  Shouldn’t it me more along the lines of “to significantly reduce risk” (or maybe even “to add functionality” if that is true?)

Cheers, Mike

Hello all,

Here’s a table with the floats, as far as I can tell.  Please check that we agree on these numbers.

The scope contingency table has been updated and is linked from the review webpage.  It’s at

Best,

Gustaaf
