目标驱动的需求工程活动支持方法选择过程

An Objectives-Driven Process for Selecting Methods to Support Requirements Engineering Activities

Lester Lobo, James D. Arthur

摘要:

本文提出了一个框架,指导需求工程师在实施和执行一个有效的需求生成过程。我们通过提供一个定义良好的需求工程模型和一个基于标准的过程来实现这一目标,以优化伴随活动的方法选择。与其他模型不同,我们的模型解决了完整的需求生成过程,并由定义在更充分的抽象层次上的活动组成。此外,活动目标被确定并明确说明-而不是像当前模型中那样隐含。活动目标是至关重要的,因为它们驱动着为每项活动选择方法。我们的模型还结合了一种独特的验证和确认方法,可以提高质量并降低生成需求的成本。为了帮助选择方法,我们根据其目标将常用方法映射到活动。此外,我们已经确定了方法选择标准,并规定了一套精简的方法,为我们的需求生成过程定义的每个活动优化这些标准。因此,定义的方法有助于选择方法的任务,通过使用选择标准将大量的潜在方法减少到较小的、可管理的集合。模型和方法集一起为需求生成过程的有效实现和执行提供了非常需要的指导。

英文摘要:

This paper presents a framework that guides the requirements engineer in the implementation and execution of an effective requirements generation process. We achieve this goal by providing a well-defined requirements engineering model and a criteria based process for optimizing method selection for attendant activities. Our model, unlike other models, addresses the complete requirements generation process and consists of activities defined at more adequate levels of abstraction. Additionally, activity objectives are identified and explicitly stated - not implied as in the current models. Activity objectives are crucial as they drive the selection of methods for each activity. Our model also incorporates a unique approach to verification and validation that enhances quality and reduces the cost of generating requirements. To assist in the selection of methods, we have mapped commonly used methods to activities based on their objectives. In addition, we have identified method selection criteria and prescribed a reduced set of methods that optimize these criteria for each activity defined by our requirements generation process. Thus, the defined approach assists in the task of selecting methods by using selection criteria to reduce a large collection of potential methods to a smaller, manageable set. The model and the set of methods, taken together, provide the much needed guidance for the effective implementation and execution of the requirements generation process.
