You don't _have_ to delegate DNS subdomains off to different servers or 
make different zone files for them.  It just provides a hierarchical 
branch point if different people will be managing the namespace.  If it 
is all managed together, it is fine to have records for 
a.office.example.com and a.production.example.com all in the zone file 
for example.com.
