Levels of information and technology usage in seaports differ considerably.
We have, at one level, certain seaports where information technology is not used at all: where all things are done manually. These ports tend to end up being perceived as inefficient. Moving cargo through them involves a lot of physical paper clearance. Things tend to move slowly.
We have, at another level, certain seaports, where information technology is applied to just a few things. The people in charge of running such ports identify the most crucial aspects, and automate them, while letting the rest remain manual (thanks to, say, lack of resources).
Finally, we have certain seaports where information technology is applied in pretty much everything. These seaports tend to end up being extremely efficient. These are seaports where everything from cargo reception to cargo clearance and port security is automated. In some of these seaports, you may even find the typical porter having a ymail.com calendar application that is actually a Ymail extension he or she uses to keep track of ship arrival dates. Clients queries are answered fast, and things are done as fast as possible. Some ports are even moving towards automating certain aspects of crane operation and so on.
