Crowdsourcing is a process that involves outsourcing tasks to a distributed group of people. This process can occur both online and offline, and the difference between crowdsourcing and ordinary outsourcing is that a task or problem is outsourced to an undefined public rather than a specific body, such as paid employees. Crowdsourcing is distributed problem solving. Your most complex business problems are broken down into microtasks and completed efficiently by an on-demand, scalable workforce. Coining the term of "crowdsourcing", Jeff Howe has also indicated some common categories of crowdsourcing that can be used effectively in the commercial world. Some of these web-based crowdsourcing efforts include crowdvoting, wisdom of the crowd, crowdfunding, microwork, and inducement prize contests. Crowd is an umbrella term for people who contribute to crowdsourcing efforts.
Crowdsourcing can be looked at as an application of the wisdom of crowds concept, in which the knowledge and talents of a group of people is leveraged to create content and solve problems.
Crowdsourcing markets are not a first-in-first-out queue. Tasks that are not completed quickly may be forgotten, buried by filters and search procedures so that workers do not see them
Some popular uses of implicit crowdsourcing are Captcha codes and ESP Game. Crowdsourcing has the potential to be a problem-solving mechanism for government and nonprofit use.
