producing test software using labview ...

Hi friends,

For those of you who produce test software using LabVIEW,
TestStand, and C/C++, what are your biggest development problems? (By
the way, this can be hardware or software.)

Scope creep.

Incomplete or unclear requirements at the beginning.  Then as the code develops the additional requirements come in, such as

"That isn't what I meant, I want this."

"That's nice, what about if we add this."

Ravens Fan pretty much sums it up. I suppose you can add onto it being forced to deal in a specific platform due to customer requirements when you know it would be orders of magnitude easier with another platform. 

Out of curiousity, what is the purpose of the question?
