Questionnaires are also disseminated to gather opinions from end users. In addition, analysts will observe the way the current system is used to perform day-day activities, and collect data. Analysis will be conducted on the different types of documentation used to understand certain rules, processes and procedures. Finally, a joint application design (JAD) can be conduct by way of a meeting with end users. The purpose of the JAD is to gather requirements that all parties can agree on (Valacich et al,

Validation of requirements to ensure there are no errors or problems with the plan and correcting any errors or problems that may surface.

The specifications are important aspects in assisting in the reduction of risk, as once written, they are helpful to users including the auditors, implementers, and maintainers. According to Hackney (2011), during system auditing, specifications provide information used to generate test data, build stubs, and analyze information flow. During system integration, they reduce the number and severity of interfacing problems by reducing the number of implicit assumptions. Specifications are usually much easier to understand than are implementations—thus combining specifications is less work than combining implementations. By relying upon those properties guaranteed

The steps of phase A are about turning the request for architecture into a documented Architecture work statement and make sure the enterprise is willing to change its architecture. This includes establishing the architecture project, defining its scope, and confirming and elaborating architecture and business principles. This phase identifies the stakeholders, their requirements and business goals from the preliminary phase.

Requirements Analysis is known as the process which allows us to understand the customer needs and expectation from proposed software. It is

In the system requirement modelling this in be a fact gathering for information or fact finding, questions will be place to our customer such as surveys, face to face interviews so we can

Requirements Engineering (RE) is and very important phase in the software development because it is this process that gives us a base for the overall software development process. This process gets even difficult and it requires more attention when the stakeholders are separated in different geographical location and have different languages and live different cultures. Requirements engineering deals with getting the needs of the customer understand the requirements of the system to be developed. In this process we also have to understand the constraints and adapt to those constraints during the process. Global Software Development is making the practice of requirements engineering a vital one. D. Zowghi, (2003) states that as software development has progressed today, it can be said that

Requirement elicitation is a critical and essential activity in the requirement engineering processes. It is a finite set of activities that complied in determination process of the system requirements. This includes identification of the system’s stakeholders, analysis of the current problem definition in application domain, an operating environment of the system and of all customers’ business and organizational environment. One of the major aspects in the failure of software projects is an improper system requirement.

The first step in requirement engineering process is requirements elicitation. Requirements should be gathered first then it can be analyzed, modeled and documented. In the requirement elicitation process, requirements are gathered through interviews, questionnaires, workshops, user observations, prototyping, brainstorming, use cases etc. Requirement elicitation practice can be used to the fullest extent when we follow some guidelines; some of those guidelines are,

This paper presents an overview of software systems requirements engineering (RE).The requirement engineering is the process of eliciting individual stakeholder requirements and their needs and evolving them in depth. And then granted requirements is documenting in a form that is responsive to analysis and communication and specified that they can serve as the basis for all other system development activities. This research paper provides a wide-ranging and well-structured introduction to the fundamentals, principles, and techniques of requirements engineering. In this paper they presents agreed techniques for eliciting, negotiating and documenting as well as validating, and managing requirements for software-intensive systems. The various phases of the process and the techniques are demonstrated using numerous examples and their work in industrial collaborations. Their presentation aims at professionals, students, and lecturers in systems and software engineering development. The Professionals people such as software architects, project managers, and software engineers will profit in their daily work from the well-presented mixture of validated measures and industrial experience. Students and lecturers will appreciate the complete description of sound fundamentals, principles, and techniques. It provides one of the clearest definitions of RE: “Requirements engineering is the branch of software engineering concerned with the real-world Goals for, functions of, and

Analyze and Validate Requirements : The requirements are analyzed and validated, and a definition of required functionality is developed.

In the research paper “Requirements Engineering: A Roadmap”, the authors Bashar Nuseibeh and Steve Easterbrook state that the “primary measure of success of a software system is the degree to which it meets the purpose for which it was intended”. Requirements Engineering is also considered a branch of systems engineering because

The end result for not unclear requirements will result in frustration for both customers and developers. The customer’s frustration will be that the product will not support its essential task and the developer’s frustration will be to implement the customer’s essential requirements after the system has been implemented. Requirements’ gathering is very difficult because it necessitates the involvement of a number of stakeholders during the phase such as customers, users, requirement analyst, developers, testers, document writers, managers, legal staff, manufacturing staff and support staff. The main failures for requirements not

In this stage, both the software developer and the customer would come together to lay out the aim of the system software, in addition, information such as requirements of the software system are put to light, not withstanding information which contribute to the outcome of the software.

Requirement specification plays an important part in the analysis of a system. Only when the requirement specifications are properly given, it is possible to design a system, which will fit into required environment.
