OK. I admit it. I am hooked -- the Wii and even my daughter's DS! That's why I love this SOA reference!
Sega, as a computer game company has received worldwide praise. While focusing on their core content, Sega as a company has produced entertainment products and services one after another. In recent years it has released hit products creating a market for children’s computer entertainment, including “Mushi [Bug] King, The King of Beetles”.
The company aims at dynamically developing businesses with unique products that can create new game markets, like the first ever sensory video games, “Hang-on”, and “UFO Catcher” did in the past. New ideas and new ideas are the two most important requirements for succeeding in doing this, though of course since it is also necessary to smoothly hitch a timely ride on market trends, speed is essential for such development. This means that the information systems supporting such development, must also be very fast.
To meet this demanding business landscape, Sega had to rethink their IT systems to enable business. They decided that the solution was to build a human workflow system using Business Process Execution Language (hereinafter “BPEL”) with a Service Oriented Architecture. It could then define things like service orders and branches accessed during business processes.
For the execution environment for the BPEL human workflow system, they use IBM WebSphere Process Server IBM WebSphere Integration Developer for development. The basic principle was to start small, and initially it focused on building a new human workflow engine and a new payment slip workflow system which use BPEL for its basic functions.
After implementing this, the project grew to be company wide. Their business processes included circular memoranda of approval and 30 old workflow systems that would have been wasteful to just eliminate them, but remaking them would have been very costly. So they decided to take an SOA approach and to wrap as services the processes of the old workflow systems, allowing them to seamlessly connect with the new workflow system. What the users see is identical to what they saw before, and the application procedures are as simple to use as they were previously.
When it is demanded, each unit of existing assets is individually wrapped so through loose coupling the new system can access it as a service, thus making real the potential of SOA while designing a new process layer.The system is extremely agile and productive from the design and development stage through operational implementation.
