Crowdsourcing
Crowdsourcing consists of opening a task or challenge to an external community to obtain distributed contributions
What it means, how it is used and where it comes up, with its related concepts.

It can be used to generate ideas, gather information or solve problems. It requires defining participation, compensation, rights over contributions and selection criteria. Receiving many responses does not guarantee diversity or quality, so evaluation must be part of the design.
