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.

Cost of quality for crowdsourcing management / İren, Deniz; Bilgen, Semih; Department of Information Systems (2014) Crowdsourcing is a business model which allows practitioners to access a rather cheap and scalable workforce. However, due to loose worker-employer relationships, skill diversity of the crowd and anonymity of participants, it tends to result in lower quality compared to traditional way of doing work. Thus crowdsourcing practitioners use certain techniques to make sure the end product complies with the quality requirements. Each quality assurance technique used in crowdsourcing impacts the project cost and s...
Quality integrated earned value management for construction projects Akgün, Eray; Atasoy Özcan, Güzide; Department of Civil Engineering (2019) Today, construction sector is one of the leading sectors in the world employing millions of people and creating an economy of billions of dollars.
