Narrative:

A falcon jet departed mia heading 090 degrees. On initial contact I assigned the jet -- climb and maintain 7000 ft. I was working the mia north departure sector (D). About 10 NM east of mia; the falcon turned north on its RNAV route (hedly 1). It should have stayed on the 090 degree vector until turned to another heading or cleared to a fix on the RNAV departure. Luckily; there was no other traffic for the aircraft to conflict with. This is a potentially dangerous situation. We should cancel these RNAV SID/stars now.
