Engagement by Design Cards: A tool to involve designers and non-experts in the design of crowdsourcing initiatives

In today's world, crowdsourcing initiatives have gained wide adoption. However, in crowdsourcing initiatives, sporadic use alone is not enough for the application to be successful, achieve its results, and have a critical mass of information. Users need to be actively engaged. Users' engagement (UE) behavior refers to continuous interaction with a solution after adoption. Failing to engage users can have detrimental effects on the overall solution. To address this, we have created an 18-card deck offering designers domain-specific insights on boosting user engagement in crowdsourcing initiatives. We utilized the cards in ten collaborative online design workshops to provide participants with valuable information. We reflected on the workshop's perceptions and the use of the cards. The findings derived from these workshops were then discussed, emphasizing their contribution to advancing design research and design practices in crowdsourcing initiatives, particularly in the context of user engagement at design time.
