How is DPP different from FSS?
DPP would process letters and flats; FSS would process only flats. DPP would output “packaged” mail; FSS would sequence flats in delivery order. DPP would eliminate Delivery Point Sequenced (DPS) letters; FSS would not have any affect on DPS letters. DPP would eliminate most carrier casing; FSS would eliminate some flats casing. DPP would improve street productivity; FSS may not.
