Besides literary research on the topic, and drawing a model for crowdsourced requirements engineering, a case study was conducted about crowdsourcing requirements and user needs for usage of behavioural data on KoiraNet breeding database. A Facebook group was founded for the project and with an open call there were eventually 107 members in the crowd. The findings of this study consists of the requirements themselves and the quantitative data from the observation of the group\u2019s activities. For assessing the requirements provided by the crowd, three separate interviews were made to experts to elicit the requirements for the same part of the system. The aim was to compare the crowdsourced requirements elicitation and priori-tization to a more traditional method. The results showed that crowdsourcing is a potential technique for requirements engineering and Facebook can be used as crowdsourcing platform, although with certain condition. Only part of the requirements from the crowd and the experts were the same, so the conclusion of this study is that the methods are complementary to each other. The organization though valued higher the requirements from the crowd. Crowdsourcing required an active participation from the crowdsourcer and a lot of trust to-wards the crowd to get results. Therefore this study concludes that crowdsourc-ing is not an easy method for requirements engineering, although it gave a great opportunity to gain highly valuable information of the real user needs.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Saija Koivula (sasijoko) on 2017-06-29 07:47:34.352405.
