INTRODUCTION:
Requirement Engineering is the initial and crucial step in the Software Development. In the past few years Requirement Engineering phase has been given much of an importance, it basically refers to gathering of information from the client that is required for the development of the project. This phase is crucial as it forms the foundation of the project. The Requirement Engineering phase is broke down into three stages, Requirement Elicitation, Requirement Specification and Requirement validation.
This paper is going to discuss the various techniques that are generally practiced for Requirement Elicitation. The term Requirement Elicitation refers to gathering of information about the project from clients, users and other stake holders. It is quite a complicated process as the user never really knows what exactly he wants, the information cannot be collected just by asking different questions about the project. There are various techniques that are in practice for this purpose. Rest of this paper discusses about such techniques along with their pros and cons.
SEARCH STRATEGY:
The data that is collected for this paper is obtained from various articles and research papers. Search Engines like Scholar.google.com and csulb.edu/library have been used for the searching purpose. The articles are selected based on the requirement i.e. the articles that
The commonly used methods of observation, interviews, etc., can help analysts pinpoint exact requirements based on user input and business processes. According to Charvat (2003), “One of the biggest benefits of a proper user requirements specification is that you'll be able to plan and estimate your project correctly, decreasing the chance of cost and time overruns.” The analyst must listen to the employees and gain a thorough understanding of all business processes before establishing the new system requirements.
Which is requirements needed, after all the information the team will analyze to determine software requirements and generate a report. Then we move to the selection and design, this will occur when the team creates several designs and share with everyone on the project. We will identify any weakness, if we have any successful prototypes it should show how the software will operate. Implementation phase should proceed without any issues if there is any it must be correct during this time. A planned out schedule should allow for any unexpected incidents. When the implementation stage is complete we move to operation when our software has been designed and does what it was designed to do. We will do a review and evaluation which consist of performance, cost and

In this work related project analysis various information will be for gathering information. Some of the areas that will be covered are; methods of searching, interviewing techniques to gather the information, agreement for articulating requirements, and strategies to gather information for computerization. Requirements must

The paper will begin with a Review of the Research. This section will summarize all the information gathered for this paper. Here the background will be given and the foundation laid for the rest of the report. Next will be the Application of the Research. This is
The information system’s requirements in the systems planning phase are based on a case summary, potential interview questions, and the systems analyst’s experience in systems planning. One must not only generate requirements based specifically on what users’ state they want or need. Analysts must also generate requirements based on insight into the overall organization and project goals.
Requirement Analysis: collect the business needs, document the requirements, and help team members to prepare Functional and enhancement Specification Document and Technical detail design document.
A Computer Software Engineer develops software systems to be used by their clients, such as a website used to sell the client’s products. Although software engineers spend the majority of their time programming and testing the software, a key component to the success of a software engineer is the ability to write a thorough Software Requirement Specification (SRS). A SRS documents the requirements and dependencies needed for the software, prior to beginning any programming. Therefore, a Software Engineer must po The SRS is so important because engineers can have a wide scope of clients that they regularly work with.
Fact-Finding and Reviewing existing system are the first step to get the requirement, after review the interview summaries, which include the main problems, unsystematic record keeping and standard in putting data into the system. According to the role system analyst (Rosenblatt, 2014), system analyst will associate with project manager in order to investigate and identify the issues that need to fix. Moreover, they will transform the business requirements into IT implementation, which will pass the requirement to the design process and prototype respectively.
According to Glass, resources are acceptable if 15-30 of the project effort was spent on the requirements definition. In regards to correctly obtaining valid sources of knowledge without saturating requirements, it was found that involving customers, consulting all resources and involving highly skilled people was the most successful approach. Furthermore, processes that involved the concentration of prioritization, traceability and validation of requirements was also recommended.

The intent of this paper is to analyze and evaluate the research problem, design, methods, and results, including limitations while offering suggestions from a different point of view to make improvements for future
The requirements gathering and analysis phase is the most critical phase for the overall success of the project because this phase helps “identify and capture stakeholder requirements using customer interviews and surveys” (Smith, 2016). In order to successfully capture software requirements from the stakeholder, developers need to conduct conference meetings to understand the capabilities of the software. This conference meeting usually takes place only once, so it is essential that developers collect all the information required for the software during the elicitation requirement meeting. For developers to be successful in collecting all the required information, it is a
