4.3.1 Use Case DiagramTo understand the system requirements, at first the researcher needs to identify theactors who will be using the system. From the high level business point of view, theusers would be those who are involving in colour supply chain of textile industry, suchas colour specifiers, middlemen, and mills (colour suppliers).However, as described in the previous chapter, the researcher is planning to constructcolour communication Web services which could be reused and further extended by anythird party Web-based applications, and these Web applications will be communicatingwith the proposed Web services via SOAP messages, therefore the actors in the contextof the proposed system would be any third party Web-based applications that areinvolving in the colour communication process of the textile industry.Next, the researcher needs to identify the functional requirements with highcommonality across the colour supply chain so that most of the applications along thecolour communication process of textile industry can be made use of the proposed Webservices.The functional requirements in which reflect the common actions done by differentactors across the colour supply chain of textile industry would be depicted by the usecase diagram on the next page:62
