SID's and STAR's exist primarily to cut down on frequency congestion and pilot/controller workload. If everyone is playing from the same sheet of music and knows what is going to happen, then it makes life simpler for everyone involved.
Example of a clearence without SID's and STAR's from memphis to st. louis:
KMEM direct MAW direct CGI CGI 335 degree radial to QBALL then STL 156 degree Radial to CHIKN direct KSTL.
Example of a clearence with SID's and STAR's (same route):
Memphis 5 depature MAW QBALL 3 arrival KSTL
See the differance? Lots easier for both parties involved.
The FAA decides which airports will have SID's and STAR's, then after a period of industry review they are put into use.
Oh yeah.. almost forgot! SID's are called DP's now (Departure Procedures). Old habits die hard.

Damn it all! Just as I was beginning to learn about instrument flying.
It's like the time when I tried to file a flight plan for a PA161-28 (Piper Warrior). The FSS guy didn't know what I was talking about because they changed it to P28A! Glad I was notified about that one... I only found out about that after reaching another FSS guy.
