In: Proceedings of the 24th Annual ACM Symposium on User Interface Software and Technology, pp. Being able to modify the software as per requirements in a systematic and controlled manner is an extremely important part of the requirements engineering process.Ahmad, S., Battle, A., Malkani, Z., Kamvar, S.: The jabberwocky programming environment for structured social computing. It should be ensured that the SRS is as modifiable as possible so as to incorporate changes in requirements specified by the end users at later stages too. This stage takes care of the changing nature of requirements. Requirement management is the process of analyzing, documenting, tracking, prioritizing and agreeing on the requirement and controlling the communication to relevant stakeholders. Reviews, buddy checks, making test cases, etc. The requirements should be practically achievable.The requirements should be complete in every sense.The requirements should be consistent with all the other requirements i.e no two requirements should conflict with each other.If requirements are not validated, errors in the requirement definitions would propagate to the successive stages resulting in a lot of modification and rework. Validation: It refers to a different set of tasks that ensures that the software that has been built is traceable to customer requirements. Verification: It refers to the set of tasks that ensures that the software correctly implements a specific function.

Requirements verification and validation: The models used at this stage include ER diagrams, data flow diagrams(DFDs), function decomposition diagrams(FDDs), data dictionaries, etc. During specification, more knowledge about the problem may be required which can again trigger the elicitation process.

All the requirements including the functional as well as the non-functional requirements and the constraints are specified by these models in totality. This activity is used to produce formal software requirement models.

Instead, it widens the domain knowledge of the analyst and thus helps in providing input to the next stage. Elicitation does not produce formal models of the requirements understood. The techniques used for requirements elicitation include interviews, brainstorming, task analysis, Delphi technique, prototyping, etc. The various sources of domain knowledge include customers, business manuals, the existing software of same type, standards and other stakeholders of the project. It is related to the various ways used to gain knowledge about the project domain and requirements.
