It is pertinent to mention here that we have to develop / draw a Sequence diagram for each and every Use Case. The Sequence diagram is one of the most usable and useful diagrams to represent the interaction of one or more objects’ interactions with one or more systems. The sequence diagram is a tool of Unified Modelling Language (UML) that represents the interaction of different actors with the system in order to get a result/response (Bell, 2004). This can reduce misunderstandings and prevent delays or mistakes in the development process.The sequence diagram is a critical part utilized in procedures of analysis and design documentation of user requirements. By clearly defining the system's functionalities and use cases, the project team can ensure that all stakeholders have a common understanding of what the system will do and how it will work. This is important because stakeholders may have different expectations and interpretations of the system's scope.
