Requirement Development Life Cycle: The Industry Practices

摘要

Requirements engineering activities act as a backbone of software development. The more efforts devoted during requirements engineering activities guarantee a better software product. Appropriate selection of requirements has been a challenge for software industry. This selection will increase the probability of success of the software product. Each year many cases are registered against companies for not fulfilling product requirements appropriately. The product failure mostly depends on, either by missing important requirements or capturing irrelevant requirements. SDLC consists of stages where software starts from scratch to a refined product. Requirements Development Life cycle (RDLC) consists of stages where requirements gets initiated, raised, refined, forcefully changed, implemented and validated. The processes to capture requirements vary industry to industry. This paper presents several requirements engineering processes used during the development of requirements, in industry. These processes will identify appropriate requirements and develop a quality product within budget on time. These practices are captured within the Pakistan software industry. This paper also explains the motivations for selecting particular methods, within company, during requirements development and the results associated with it. The processes captured in this paper, from different companies, can be an education for software industry.
