Services can then be published in registries public to all national headquarters, thereby
becoming available for process composition. Semantic description and publishing
of Web services deliver interoperable business services, which mean that services
will exhibit consistent accessibility to any business process composite that wish
to use it. Both stock management and purchase management processes may use
a service that returns product stock levels in sibling headquarters and discovering
and binding to that service will execute identically. Business operations planned
for reengineering should be modeled from scratch and services recognized as parts
should be described and published. Product availability and product stock level
requests are business services that already exist in current stock management and
purchase management processes.
By enabling national headquarters to publish loose-coupled, commonly accessed
Web services the company becomes capable to compose highly automated business
activities, avoiding thus human intervention. Services participating in a composite
process of stock, purchase, or financial control are now selected from common
pools (service registries).
