This paper demonstrates Helius, a collaborative Design Thinking (DT) techniques recommendation system. We proposed Helius to support DT practitioners in selecting DT techniques for use in software development, as literature has shown that selecting a set of DT techniques can be a complex decision-making problem. To develop Helius, we followed a Design Science Research framework, starting with a deep understanding of the problem and followed by three iterations of design and validation activities. In total, 40 professionals participated in the validation activities for Helius. The results show that Helius effectively supports the selection of DT techniques and is considered by DT practitioners to be a useful and easy-to-use recommendation system.

Diversas técnicas de Design Thinking (DT) têm sido usadas no desenvolvimento de software para fomentar a empatia, a colaboração, a criatividade, e auxiliar as equipes a entender as necessidades do usuário, gerar várias ideias, prototipar e selecionar a solução que atenda tais necessidades. Portanto, neste universo de várias técnicas, selecionar quais delas utilizar para o desenvolvimento de software configura-se como um problema de tomada de decisão. Contudo, há uma ausência de recursos que disponibilizem espaços para que os profissionais de TI que usam o DT possam compartilhar suas experiências, ou possam coletar informações que auxiliem na tomada de decisão de quais técnicas usar. Neste sentido, inspirados no modelo Spotify de organização de equipes, este artigo apresenta insights de uma proposta que visa promover uma comunidade colaborativa a partir de experiências de profissionais com o uso de técnicas de DT. Dessa forma, este artigo busca contribuir com a seleção de técnicas DT para o desenvolvimento de software.

Resumo This paper reports further on Helius, a collaborative recommendation system of Design Thinking techniques for software development. DT has been using as an approach for problem-solving, supporting software development activities such as Requirement Engineering (RE). DT integrated to RE fosters empathy, team collaboration, creativity, and an innovative mindset putting the user needs at the center of the development process. DT provides a large set of techniques, including Interviews, Brainstorming, Personas, User Journeys, Prototyping, etc. Therefore, selecting the DT techniques for RE activities becomes a challenge, mainly for novice professionals. This way, Helius uses professionals' experiences and techniques evaluations as collaborative resources to recommend DT techniques. Helius' proposes resulted from a DT session with software development professionals and researchers. Helius presents innovative features when compared with similar tools. Therefore, we expect to support software development professionals in selecting DT techniques and collaborate with the DT adoption in software development.
