Several years ago, I created a PO in Word and sent it to all of our AE's. They are very comfortable with filling it out and sending it to me via email along with the script. The send the email to our traffic and production departments. No paper printed!! It is very efficient, and filing is so much easier when it's all electronic.
I'm amazed to see how many radio stations are still doing everything with printed or hand-written production orders in 2012. The waste of paper and the burden of filing all of that paper is ridiculous in today's technology-filled world.
My next step is to create a form on our intranet that the AE's will fill out. Once filled out, the form will automatically email a copy to production, traffic, and the AE. Creative PPO looks interesting. I'm gonna check it out.
