【摘要】 需求来源于不同利益相关方对现实系统的认识和期望。需求获取在整个软件产品的研发过程中至关重要,往往决定着软件产品的质量甚至成败。然而,由于各种复杂因素的影响,获取到的需求中往往存在不完整、不准确甚至冲突等缺陷。需求表达上的二义性、需求描述的不完整和不一致等是最常见的需求缺陷。文中提出一种基于多视角需求获取的卡牌模型和需求缺陷检测规则。在需求获取过程中,特别是在其初期,其能够发现来自各方需求信息中常见的不完整和不一致需求缺陷。最后,通过3组项目案例验证了方法的有效性。更多还原

【Abstract】 Requirement stems from the understanding and expectations of different stakeholders on the real system.Requirement elicitation is crucial in the whole process of software product development,and it often decides the quality of software product,even its success or failure.Due to the influence of various complex factors in the elicited requirements,there are some defects such as incompleteness,inaccuracy and conflict.The ambiguity of requirement expression and the incompleteness and inconsistency of requirement description are the most common requirement defects.This paper proposed a card model based on multi-view requirements and requirement defect detection rules.In the process of requirement acquisition,especially in the early period,the incomplete and inconsistent requirement defects from stakeholders can be found through requirement defect detection rules.Finally,the validity of this method is verified by the experiment on three project cases.更多还原
