Requirements Engineering in Agile Software Development

This article compares traditional requirements engineering approaches and agile software development. Our paper analyzes commonalities and differences of both approaches and determines possible ways how agile software development can benefit from requirements engineering methods.

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.

Interest in the adoption of Agile methodologies has grown in recent years as a strategy to minimize problems in software development. However recent studies indicate high rates of failure also in projects that use agile processes. In this context, this research conducted an exploratory study to investigate how Requirements Engineering is used in projects that adopt agile methodologies. For this, a Systematic Mapping was performed and it identified the engineering requirements techniques that are running in the industry, the problems and limitations in projects that adopt agile methodologies. The low involvement of users and the constant changes of requirements were identified as the main challenges to be overcome.

Developing software that meets the customers or stakeholders' needs and expectation is the ultimate goal of the software development methodology. To meet their need we have to perform requirement engineering which helps to identify and structure requirements. In traditional software development methods end users or stakeholders predefined their requirements and sent to the development team to analysis and negotiation to produce requirement specification. In many cases it is risky or very difficult and not economical to produce a complete, verifiable set of requirements. Traditional software development has a problem to deal with requirement change after careful analysis and negotiation. This problem is well tackled by the Agile Practices as it's recommends an on-site customer to represents their requirements through user stories on story cards. Generally customers have rarely a general picture of the requirements or system in their mind which leads problems related to requirements like requirements conflicts, missing requirements, and ambiguous requirements etc, and does not address non-functional requirements from exploration phase. This chapter introduces best knowledge based guidelines for agile requirements engineering to enhance the quality of requirements (story cards).

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 software processes, while rich with support for requirements activities, are not especially well suited for rapid software development. Agile software processes have recently received increased attention due to the need to develop software for rapidly changing environments; however they fail to properly support essential requirements engineering practices. This paper proposes a agile approach to software development, ADaPT (Agile Development and Prototyping Technique), which employs proven scenario and goal-based analysis techniques to elicit and structure requirements, ensuring that system requirements are iteratively examined via prototyping. ADaPT incorporates the concept of "user stories" in extreme programming and scenarios as traditionally used in requirements engineering. While introducing rigor into requirements activities, agility is maintained in ADaPT by documenting only the most essential elements. Validation is currently underway on several software development efforts that employ the model to support rapid development of electronic commerce applications.

Understanding and fulfilling each individual customer requirements has been recognized as a pressing challenge for software industries. To produce high quality software products and meeting stakeholder's requirement is a major challenge in software requirement. Poor requirements and changes to requirements are one of the causes for project overrun and quality issues in the delivered software. The paper discusses about how the different agile methodologies follow requirement management steps in a project. It tries to give an idea to those organizations who undergo projects with frequent change in the requirements so that they can produce quality products and survive in the market strategy.

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...

In the past few years, there has been an increasing awareness of the important role of requirements engineering (RE) in a project's success, in both research and industry. Developing consistent requirements specifications that meet the customers' needs, in traditional development, is likely to be infeasible. For one reason, customers do not usually have a clear picture of what they really want. Secondly, the business domain could be changing quickly, especially if it heavily depends on technologies. Agile software development (ASD), on the other hand, supports iterative and incremental development and emphasises customers' involvement in the development process. We argue that adopting ASD in RE overcomes the limitations of the traditional development. ASD, however, is no silver bullet and its adoption comes at a price. This paper helps the reader to: (1) get a quick yet a comprehensive grasp of RE in traditional and ASD; (2) understand the synergies/commonalities between the two approaches in handling RE; (3) recognise the associated challenges of adopting ASD; and (4) identify the current prominent agile RE research areas.
