Abstract

Over the last decades, software development effort estimation has integrated new approaches dealing with uncertainty. However, effort estimates are still plagued with errors limiting their reliability. Thus, estimates error management at an organization level provides a promising alternative to the classical approaches dealing with single projects as a portfolio can afford more flexibility and opportunities in terms of risk management. The most widely used approaches in risk management were mainly based on the Gaussian approximation that shows its limits facing “ruin” risk associated to unusual events. The aim of this paper is to propose a Multi-Projects Error Modeling framework to characterize error at a portfolio level using bootstrapping, mixture of Gaussians and power law to emphasize the tail behavior respectively.

项目组合的软件工作评估和风险管理
在过去的几十年里,软件开发工作量评估已经集成了处理不确定性的新方法。然而,工作量估计仍然受到限制其可靠性的错误的困扰。因此,组织级别的估计错误管理为处理单个项目的经典方法提供了一个有希望的替代方案,因为组合可以在风险管理方面提供更多的灵活性和机会。风险管理中最广泛使用的方法主要是基于高斯近似,它显示了它面对与异常事件相关的“破产”风险的局限性。本文的目的是提出一个多项目误差建模框架,在投资组合水平上分别使用自举、混合高斯和幂律来表征误差,以强调尾部行为。
