Crowdsourcing involves outsourcing tasks traditionally done by employees to a large group of people. It allows companies to tap into talent outside their own organizations. Crowdsourcing problems are broadcast to an unknown group who submit solutions, which are then sorted and evaluated. There are four main types of crowdsourcing: crowdfunding, crowdcreation, crowdvoting, and crowd wisdom. Crowdsourcing provides benefits like low costs, access to wider talent, and customer insights. It differs from outsourcing in that tasks are done by an undefined public rather than specific contractors.
