Unless an organization is starting jobs using an adhoc method, scheduling plays a major role in EDI implementations. Scheduling during EDI projects is unfortunately very often taken for granted. However, very frequently a lot of EDI jobs error out in their first few weeks of production because enough thought does not go into the scheduling process.
Seems like today, given the fact just about everyone has a mobile phone (including the four-year-old my daughter played with today; granted it was a hand-me down from the parents, but it still worked!), that supply chain executives would want to access pertinent data away from their desks, while out and about and on the move.
