  self-describing piece of application
  functionality that can be found and accessed by
  other applications using open standards

  service is contained in the service

  use the service is contained in the service

Web Services

• Business processes are configured by stringing a
  series of web services together to accomplish the
  process
• For example, to cancel a customer order requires
  sending a confirmation to the customer, removing
  the order from the production plan, releasing
  materials, notifying the invoicing department,
  etc.
• Each of these activities would be offered as web
  services from the various systems involved
• Processes can be easily modified by rearranging
  the services used
