Hello all,

Today’s update:

-I have approved 6.5.4, 6.6.3 and 6.8.4.

-for 6.6.1 I have a question: the text says "Some of the expenses for […] have not yet been paid”, but expenses not being paid doesn’t lead to a cost variance.  Do you mean to say you have forgotten to accrue them?  I’ve unlocked this.

Thanks,

Gustaaf

I've removed the SPI comment and revised the CPI statement to make clear that the general trend is down but this month it was up because of the discretization of the task ends.

Hello all,

Thanks to those who filed their VRs in time.  Comments on those below.  We are still missing 6.5.4, 6.6, 6.6.1, 6.6.3, 6.6.4.

-6.4 I have approved
-6.4.1 I have approved.
-6.4.3: 280k schedule variance has no impact?  That seems hard to believe, but if true it would be good to explain why there is no impact.  I’ve unlocked this.

-6.8.1 I have approved
-6.8.4: Please remove everything related to schedule variance since (as you say) this is now below threshold.  For the cost variance, the statement made doesn’t align with having a positive $83k CV this month.  I’ve unlocked this.

Best,

Gustaaf
