Research has shown that multiple redundant results delivered by different workers can be aggregated in order to achieve a reliable result. However, basic implementations of this approach are rather inefficient as they multiply the effort for task execution and are not able to guarantee a certain quality level. In this paper, we are addressing these challenges by elaborating on a statistical approach for quality management of people services which we had previously proposed. The approach combines elements of statistical quality management with dynamic group decisions. We present a comprehensive statistical model that enhances our original work and makes it more transparent. We also provide an extendible toolkit that implements our model and facilitates its application to real-time experiments as well as to simulations. A quantitative analysis based on an optical character recognition (OCR) scenario confirms the efficiency and reach of our model. <\/jats:p>","DOI":"10.1142\/s0218843012400011","type":"journal-article","created":{"date-parts":[[2012,3,23]],"date-time":"2012-03-23T15:27:00Z","timestamp":1332516420000},"page":"3-29","source":"Crossref","is-referenced-by-count":10,"title":["DYNAMIC AND GOAL-BASED QUALITY MANAGEMENT FOR HUMAN-BASED ELECTRONIC SERVICES"],"prefix":"10.1142","volume":"21","author":[{"given":"ROBERT","family":"KERN","sequence":"first","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Karlsruhe Service Research Institute, Englerstra\u00dfe 11, 76131 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HANS","family":"THIES","sequence":"additional","affiliation":[{"name":"SAP Research, Blumenbergplatz 9, CH 9000 St. Gallen, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CHRISTIAN","family":"ZIRPINS","sequence":"additional","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Karlsruhe Service Research Institute, Englerstra\u00dfe 11, 76131 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GERHARD","family":"SATZGER","sequence":"additional","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Karlsruhe Service Research Institute, Englerstra\u00dfe 11, 76131 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,4,6]]},"reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.1145\/1869086.1869094"},{"key":"p_7","first-page":"7","author":"Dodge H.","year":"1951","journal-title":"Ind.
