In the airline you work for its very clear in the performance handbook
''In VMC conditions provided terrain clearance is not in doubt, and airplane mass and climb performance are adequate the pilot may
-Accept radar vectoring by ATC or
-Follow the departure route or
-Remain visually in the vicinity of the airfield
If unable to insure the above conditions, the published EOSID or special EOSID should be adpoted''
Hope that answers your question.
