Managers are regularly confronted with unsolved problems. If a manager knows who can solve a problem, they can assign the problem to the correct person to have it solved under an ex ante contract or other form of agreement/commitment, inside or outside the organization. If they do not know who can solve it, they can crowdsource it, broadcasting the problem to an undefined set of people (the crowd) to self-select and solve it with no ex ante contract or other commitment. Although the practice of crowdsourcing goes back to at least the Longitude Prize of 1714, research on the phenomenon has only recently flourished, thanks, in part, to advances in information technology, globalization, and other macro-environmental factors. This chapter presents a crowdsourcing primer and framework with the goal of providing management scholars with some of the fundamentals needed to pursue their research interests in this compelling phenomenon.
