Abstract

Even though crowdsourcing was introduced as a novel business model for risk prone entrepreneurs, in time it has become a valid means of producing value in large scale projects as well. However due to loose employee - worker relationship, quality continues to be a serious issue for crowdsourcing. Therefore, various quality assurance mechanisms are used in crowdsourcing. Quality assurance significantly impacts project costs. However the literature lacks defined ways to estimate costs of quality and guidelines for selecting the most cost-effective mechanism. In this paper we introduce cost models, which may be used to estimate crowdsourcing costs and act as a guideline to efficiently utilize quality assurance mechanisms. These models were developed through a Cost of Quality (CoQ) approach, which has been widely used in total quality management since the 1970's. To demonstrate the applicability of our approach, we present the results of an experiment in which cost models are applied on subjective, non-deterministic microtask type crowdsourcing.
众包中质量保证的成本模型
尽管众包最初是作为一种新颖的商业模式引入风险偏好的企业家的,但随着时间的推移,它也已成为大型项目中创造价值的有效手段。然而,由于松散的员工关系,质量仍然是众包的一个严重问题。因此,在众包中使用了各种质量保证机制。质量保证显著影响项目成本。然而,文献缺乏明确的方法来估计质量成本和选择最具成本效益的机制的指导方针。本文引入了成本模型,可用于估算众包成本,并作为有效利用质量保证机制的指导方针。这些模型是通过质量成本(CoQ)方法开发的,该方法自20世纪70年代以来广泛应用于全面质量管理。为了证明我们的方法的适用性,我们展示了一个实验的结果,在这个实验中,成本模型被应用于主观的、不确定的微任务类型的众包。
