A number of researchers talk about requirementelicitation and use some approaches , technique , and tools to collect arequirement from user  .In 1 the first researcher used approach this approach leverages design processesand promotes realization of the required user experience, including usabilityand accessibility requirements. In this positional paper, a new approach to thetechnological evolution occurring in our complex world is proposed, whichrequires knowledge integration and the linking of diverse disciplinary fields.

The pro-posed approach aims at overcomingthe observed results and fosters enhanced processes that encompass thedifferent perspectives. We demonstrate this approach using a design objectcreated in a multidisciplinary team.In2 the second researcher used Elicitation tool is an effortless one thatvisually aids the user to state their needs more accurately as it is morepractical for the user to imagine by seeing instead of hearing. This tool canbe used by the analyst as an aid to gather requirements in a more efficientmanner compared to other existing methods.

In 3 the third researcher used technique  to overcome the problem of requirementelicitation technique for web application using a combination of interview andJoint Application Development technique between developers and users. Thistechnique will improve the requirement elicitation process and help developersand users to clearly define their requirements in web based application. Wealso anticipate this technique will decrease the time spent to develop a webapplication by using this combined technique.

 In 4the fourthresearcher  gives review of five elicitation basedtools in context with visualization of requirements to stakeholders. Benefitsand limitations of tools have been presented and the limitations reflect theaspects of improvements. In 5 Researches have identified the major causebehind software project failures to be poor RE . Requirement elicitation isarguably the most important part of the whole RE process. It is concernedprimarily with the communication between client stakeholders and engineerstakeholders.

A successful level of elicitation early on in the project isimportant in order to create a solid mutual understanding so as to not leavesome project goals out. These left out goals produce a lot of dissatisfactionfor the final project and may imply a lot of work, and cost, to implement lateron. Another kind of failure is misunderstandings of requirements.Misinterpreting and wrongly implementing requirements produce just as badresults as not implementing them at all. There are many elicitation techniquesand also methodologies that propose complete roadmaps using a combination ofdifferent techniques and tools. Some of these techniques are interviews,workshops, observational and documentation
