Previous issue date: 2018-08-13 / Software crowdsourcing development platforms require a continuous influx of crowdworkers for their continuity. Crowdworkers should be encouraged to play an important role in the online communities by being active members, but they face difficulties when attempting to participate. For this reason, we investigated the difficulties that crowdworkers face in crowdsourcing software development platforms. We conducted empirical studies relying on multiple data sources and research methods including literature review, peer review, field study, and procedures of grounded theory. We observed that crowdworkers face many barriers ? related to competence, collaboration, and time management ? when making their contributions in software crowdsourcing development, which can result in dropouts. Based on the identified barriers, literature review and, crowdworkers suggestions, we list 13 recommendations for participants as potential solutions to overcome such barriers. The recommendations were evaluated by surveying software crowdsourcing experts. The main contributions of this dissertation are a) empirical identification of barriers faced by crowdsourcing software development crowdworkers; and b) recommendations on how to minimize the barriers. We conclude that the crowdworkers need competency and an efficient time management effort to take part collaboratively in tasks of the Competition-Based Crowdsourcing Software Development of the Topcoder platform. / O desenvolvimento de projetos por meio de software crowdsourcing depende de um fluxo cont?nuo de trabalhadores da multid?o para sua continuidade. Estes trabalhadores necessitam ser membros ativos, por?m enfrentam dificuldades quando tentam participar em projetos de software crowdsourcing. Por esta raz?o, investigou-se quais foram as dificuldades que os trabalhadores da multid?o enfrentam em plataformas de desenvolvimento de projetos via software crowdsourcing. Foram realizados v?rios estudos emp?ricos baseados em m?ltiplas fontes de dados e m?todos de pesquisa, incluindo revis?o da literatura, revis?o por pares, estudo de campo e procedimentos da teoria fundamentada. Observou-se que os trabalhadores enfrentam muitas barreiras - relacionadas ? compet?ncia, colabora??o e gerenciamento do tempo - ao fazerem suas contribui??es no desenvolvimento projetos por software crowdsourcing, o que pode resultar em desist?ncias. Com base nas barreiras identificadas, revis?o de literatura e sugest?es dos trabalhadores foram apresentadas 13 recomenda??es para que estes trabalhadores possam superar tais barreiras. Estas recomenda??es foram avaliadas por especialistas em software crowdsourcing. As principais contribui??es desta tese foram: a) identifica??o emp?rica das barreiras enfrentadas pelos desenvolvedores de software em projetos de software crowdsourcing; e b) recomenda??es para minimizar estas barreiras. Conclui-se que os trabalhadores da multid?o precisam de compet?ncia e um esfor?o eficiente de gerenciamento de tempo para participar de forma colaborativa nas tarefas do desenvolvimento de projetos em software Crowdsourcing no modelo competitivo da plataforma Topcoder.
