We introduce flash teams, a framework for dynamically assembling and managing paid experts from the crowd. Flash teams advance a vision of expert crowd work that accomplishes complex, interdependent goals such as engineering and design. These teams consist of sequences of linked modular tasks and handoffs that can be computationally managed. Interactive systems reason about and manipulate these teams' structures: for example, flash teams can be recombined to form larger organizations and authored automatically in response to a user's request. Flash teams can also hire more people elastically in reaction to task needs, and pipeline intermediate output to accelerate completion times. To enable flash teams, we present Foundry, an end-user authoring platform and runtime manager. Foundry allows users to author modular tasks, then manages teams through handoffs of intermediate work. We demonstrate that Foundry and flash teams enable crowdsourcing of a broad class of goals including design prototyping, course development, and film animation, in half the work time of traditional self-managed teams.
Evidence of psychometric validity is lacking for many teamwork survey instruments. However, several psychometrically valid instruments are available. Researchers aiming to advance research on teamwork in health care should consider using or adapting one of these instruments before creating a new one. Because instruments vary considerably in the behavioral processes and emergent states of teamwork that they capture, researchers must carefully evaluate the conceptual consistency between instrument, research question, and context.
This paper shows how mesolevel structures support effective coordination in temporary groups. Prior research on coordination in temporary groups describes how roles encode individual responsibilities so that coordination between relative strangers is possible. We extend this research by introducing key tenets from team effectiveness research to theorize when role-based coordination might be more or less effective. We develop these ideas in a multimethod study of a hospital emergency department (ED) redesign. Before the redesign, people coordinated in ad hoc groupings, which provided flexibility because any nurse could work with any doctor, but these groupings were limited in effectiveness because people were not accountable to each other for progress, did not have shared understanding of their work, and faced interpersonal risks when reaching out to other roles. The redesign introduced new mesolevel structures that bounded a set of roles (rather than a set of specific individuals, as in a team) and gave them collective responsibility for a whole task. We conceptualized the mesolevel structures as team scaffolds and found that they embodied the logic of both role and team structures. The team scaffolds enabled small-group interactions to take the form of an actual team process with team-level prioritizing, updating, and helping, based on newfound accountability, overlapping representations of work, and belonging—despite the lack of stable team composition. Quantitative data revealed changes to the coordination patterns in the ED (captured through a two-mode network) after the team scaffolds were implemented and showed a 40% improvement in patient throughput time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
