Software Engineering - Old Questions

6. Why elicitation and analysis is a difficult process in requirement engineering process? Explain.

Requirements elicitation and analysis is a process of interacting with customers and end-users to find out about the domain requirements, what services the system should provide, and the other constrains.

The requirements elicitation and analysis has 4 main process:

The users, customers or other stakeholders involved in the software development do not know all the features and behavior they need to have in the software at the time of requirements gathering. End-users at first encounter are most likely to give unrealistic requirements or requirements that are filled with ambiguities. The term elicitation is a pointer to the fact that good requirements cannot be obtained simply by asking the user, customer or stakeholders what they want. Requirements elicitation therefore calls for multiple interviews, questionnaires, user observations, brainstorming sessions and lots of prototypes. This is why requirements elicitation is difficult.
