Requirements engineering and agile software development

Journal of Software Engineering & Intelligent Systems, 2018

Requirement engineering (RE) is one of the important phases of development life cycle. Many software projects are failed because that was made without enough requirements information. RE is one of a process of customer services which have to expect customer from a system. Correct executions of engineering requirements caused to reduce the cost of software projects. In the agile methods unlike traditional methods, RE agrees with the change of new requirements. In this research, a survey, about practices, techniques, challenges, and activities, is conducted in agile requirement engineering. Moreover, this survey compares traditional RE and agile RE in different aspects.

Requirement Engineering is one of essential phase in software development life cycle. In the last few years many people know much about the success rate of Requirement Engineering in a project’s success. The agile approach will produce a high standard product in less budget and time. With the passage of time, consumers will be more appealing as their technology standards increase rapidly every day. Agile software development (ASD) is an iterative and gradual approach to development that relies on the participation of customers in the development process. So, we can conclude that organizations are still struggling with agile evolution and agile values, especially when it comes to user involvement. Although much research has been carried out on the role of requirement engineering in agile methodologies and practices, more studies are still needed. The aim of this research is to analyze and compare researchers ' work, which will help those who are interested in finding interesting ...

World has turned into a global village. Fast growing economies has turned the way how world works. Old methods of software development are losing their grounds against agile development. Agile is paving its way to become the first choice of every person involved in software development. Agile development techniques are another name for delivering software product on time and within budget. Like all other developing techniques agile must have mechanisms to collect and manage requirements. This paper presents how different requirement engineering principles can be incorporated in agile development. Paper will cover different agile methods and requirement engineering techniques. There are lot of integration and differentiation in both techniques appears in this paper.

One of the important points to be considered when implementing a software project is the successful management of the requirements. The success of the software depends on the accuracy and completeness of the requirements. Knowing the positive and negative aspects, advantages and disadvantages of the existing methodologies helps for selecting the appropriate methodology and choosing the appropriate approach to the situation and the project in this direction will increase the probability of success of the project. Although there is a lot of research in the literature about the traditional and agile approaches which are the main trends of software development approaches, the publications made in specific for requirements engineering process are limited. In this study, the necessary engineering applications in traditional and agile methodology approaches are evaluated to assist in the selection of methodology.

Agile Methods are characterized as flexible and easily adaptable. The need to keep up with multiple high-priority projects and shorter time-to-market demands could explain their increasing popularity. It also raises concerns of whether or not use of these methods jeopardizes quality. Since Agile methods allow for changes throughout the process, they also create probabilities to impact software quality at any time. This thesis examines the process of requirement engineering as performed with Agile method in terms of its similarities and differences to requirement engineering as performed with the more traditional Waterfall method. It compares both approaches from a software quality perspective using a case study of 16 software projects. The main contribution of this work is to bring empirical evidence from real life cases that illustrate how Agile methods significantly impacts software quality, including the potential for a larger number of defects due to poor non-functional requirements elicitation. iii ACKNOWLEDGMENTS It has been an enlightening journey from the inception till the completion of this master thesis. During all this time of ups and downs, I was encouraged and given a lot of support by a lot of people, which I would like to thank with all my heart and sincere feelings. I would like to thank my supervisor Professor Luiz Maricio Cysnerios for giving me this opportunity and having faith in me. I am compelled to say that without his encouragement and enthusiastic support, this thesis would not have been possible. I can never thank him enough for his academic support and help.

In the past few years, agile software development approach has emerged as a most attractive software development approach. A typical CASE environment consists of a number of CASE tools operating on a common hardware and software platform and note that there are a number of different classes of users of a CASE environment. In fact, some users such as software developers and managers wish to make use of CASE tools to support them in developing application systems and monitoring the progress of a project. This development approach has quickly caught the attention of a large number of software development firms. However, this approach particularly pays attention to development side of software development project while neglects critical aspects of requirements engineering process. In fact, there is no standard requirement engineering process in this approach and requirements engineering activities vary from situation to situation. As a result, there emerge a large number of problems whi...

Complex enterprise procedures influx is rising in a very competitive ambiance of software program region, that is a very intricate condition for IT industry to curb the timelines deliverance, and penetrating for the approaches to become receptive of their strategies and necessities. This research paper gives a finer indulgent of the utilization of requirement engineering innovation techniques in the progress of agile software. Agile requirements engineering stages are shown and suggests technique that can be employ to accomplish these steps. These methods focus on a reliable connection to the customer to address the specifications progress after some time, arrange them, and provide significant features as soon as possible. This paper studies resemblances and variations of these methods to determine from these methods which one is superlative appropriate for different procedures of development of agile software.

—Traditional RE and Agile RE are two different approaches on the basis of their planning and control mechanism. This Paper distinguishes the Traditional RE and Agile RE. Furthermore it investigates the reasons for which software industries shifted from Traditional RE to Agile RE. Research is carried out by conducting a literature study and finally a case study of software development to evaluate which approach has better success rate than other. With the help of our finding and results we have evaluated that Agile RE performs better than Traditional RE in large organizations where changes evolve throughout the development phase of software life cycle.

Abstract: Collecting, understanding, and managing requirements is a critical aspect in all development methods. This is true for Agile Methods as well. In particular, several agile practices deal with requirements in order to implement them correctly and satisfy the needs of the customer. These practices focus on a continuous interaction with the customer to address the requirements evolution over time, prioritize them, and deliver the most valuable functionalities first.
