This article aims to study crowd dynamics in small teams. In particular we are specifically interested to internal crowdsourcing as a venue for innovation and new ideas production, questioning the difference with regard to other cooperative models based, e.g., on communities. Another goal of the study is to provide the setting for experiments in business domains to investigate how crowd characteristics may lower or increase “crowd capital,” here defined as the total number of crowd units having a demonstrated effectiveness in idea generation or task achievement. Thus, the article aims to contribute to the research on coordination in temporary and flash teams. To this end, the article discusses the main results of six studies carried out among management students in higher education from 2014 to 2018.
