In more or less big enterprise IT company there are many teams that never talk to each other. I never saw there is someone(s) coordinating all teams/branches/ideas/whatever else - it's probably a dream that never comes true. This leads to cases like inventing same things twice and naming two different things by the same term.
How about the use of different names for the same thing in data dictionary views. ie segment_owner,table_owner,owner,index_owner, timestamp,timestamp# etc. drives me crazy.
