Child workflows execution order - CRM 2011

Hi all,

I have a parent workflow that fires 2 child workflows. The set up is something like this:

IF (some condition)

    Start child workflow A

    Start child workflow B

Just say if A fails will B still get executed? My understanding is that A and B will run independently or does CRM automatically stops everything including the parent workflow if there is an error?

Cheers,

Stanley
