Yes, I know, and it is all good news.  However, that doesn't diminish 
the projects problems: the shear size of the branch, the number of 
dedicated full time resources currently been consumed, the constant 
schedule slip, ...

A comparison is reasonable (and it isn't ment to degrate SSA or GCC). 
If the HP merge were to have been handled correctly it would have turned 
into a project of size and logistics comparable to SSA.  That, I think, 
is getting out of control.

As I said:
