My on car routine starts just before the PCM after I have downloaded EDD. I quickly go through and use the RES/COM key for my NDA SVRs. I also check my NDA to make sure I can deliver them all on time. When on road the key word for me is flexibility, which means adjusting my routine based upon things beyond my control. For example, my first stop every day is WalMart. I can normally get right on a door but there are days when I can't. I have to decide if I want to wait or if I go to Sam's, deliver, and then come back and hope no one else is waiting for a door, knowing that I need to get rid of WalMart so that I can move around in the pkg car. I usually have the next 5-10 stops lined up in my head. Residential stops are done as efficiently as possible with little customer interaction (unless I know them and even then it is usually just a few words) while commercial stops usually allow you a little more time to bs while still making the delivery. I stay on trace at least 90% of the time but do break trace if there is a bulk stop that, if delivered, would make it much easier for me to move around in the pkg car. I have several businesses which receive CODs that, if I call ahead, will have all of the checks ready to go when I get there. I also have several customers who have my cell and will meet me on road if they need their pkgs earlier than I can get there. Pickups are handled in the same manner, following trace while maintaining the +/- 15 min window.
Being organized, focused and possessing a sense of urgency will all serve you well in this job, as will a sense of humor and the ability to not take things personally.
