Crowdsourcing New Product Ideas over Time: An Analysis of the Dell IdeaStorm Community
研究戴尔IdeaStorm社区发现，多次提交创意的用户比只提交一次的用户更可能提出被采纳的创意，但一旦创意被实施，他们后续创意多样性下降，成功难以重复；评论他人创意可缓解此负面效应。
Several organizations have developed ongoing crowdsourcing communities that repeatedly collect ideas for new products and services from a large, dispersed “crowd” of nonexperts (consumers) over time. Despite its promises, little is known about the nature of an individual's ideation efforts in such an online community. Studying Dell's IdeaStorm community, serial ideators are found to be more likely than consumers with only one idea to generate an idea the organization finds valuable enough to implement, but they are unlikely to repeat their early success once their ideas are implemented. As ideators with past success attempt to again come up with ideas that will excite the organization, they instead end up proposing ideas similar to their ideas that were already implemented (i.e., they generate less diverse ideas). The negative effects of past success are somewhat mitigated for ideators with diverse commenting activity on others' ideas. These findings highlight some of the challenges in maintaining an ongoing supply of quality ideas from the crowd over time. This paper was accepted by Kamalini Ramdas, entrepreneurship and innovation.
