Web services are software systems designed to support interoperable machine-to-machine interaction over a network. This interoperability is gained through a set of XML-based open standards. These standards provide a common approach for defining, publishing, and using web services. However after a product is introduced in the market, its successful growth against the competitors depends critically on the company´s ability to rapidly improve and extend its product in response to customer feedback.
