This is a perfectworkflow scenario .Very common transaction

Large value

Mistakes are expensive

Only thing moved is informationWhy isnt this business automated?

No dominant player to set standard

No fixed standard differences are competitive

advantage

Many varied local laws

Companies involved are small and can not afford

development toward complex interactions

Requirements

While companies are automated internally, what isneeded is a quick and easy way to link their data:

Without getting bogged down in complex processes

Without needing a programmer

Without having to change the way they work now

Without requiring that every partner be identical

ASAP offers a plug-and-play approach tolinking data of long term processes

Wait a minute

Some say: Systems designers want to send anymessage at any time without having to fit into a pre-

defined protocol.

The flexibility to define the protocol means that you have

to do the work to fully define the protocol.Using a pre-defined pattern saves a tremendous amount

of expense.

The ASAP pattern has been proven useful

By simply defining two data structures, ASAP thenspecifies all the messages necessary to control an

asynchronous service.
