Crowdsourcing is a value-creation model that distributes a task — problem-solving, content creation, data collection, product design — across a large, often self-selecting group of external contributors rather than a fixed internal team or contracted vendor. The economic engine runs on the asymmetry between the low marginal cost of soliciting contributions at scale and the disproportionately high value of the best outputs.

How It Works
Crowdsourcing inverts the traditional production function. Instead of hiring a team of ten specialists to solve a problem, you broadcast the problem to ten thousand people and let self-selection do the filtering. The contributors who have the right skills, motivation, or idle capacity step forward. The rest ignore it. The result is a radically different cost structure: you pay for outputs, not inputs — and often only for the winning output.
The critical insight is that the person best equipped to solve your problem probably doesn't work for you. Karim Lakhani and Lars Bo Jeppesen's research at Harvard Business School found that InnoCentive challenges were most often solved by people working at the margins of their own discipline — a chemist solving a biology problem, an aerospace engineer cracking a materials science puzzle. Crowdsourcing exploits the long tail of human expertise in a way that traditional hiring cannot.
Monetization varies dramatically by implementation. Some crowdsourcing models are cost-avoidance plays — Wikipedia's volunteer editors replace what would otherwise be a billion-dollar editorial operation. Others are revenue-generating platforms that charge problem-posters a fee (InnoCentive charged companies $20,000–$1,000,000+ per challenge). Still others use crowdsourced contributions as a product input that feeds a separate revenue model — Waze's user-reported traffic data made the navigation app valuable enough for Google to acquire it for $1.15 billion in 2013.

The central strategic challenge is quality control at scale. When you open the aperture to thousands of contributors, you get a power-law distribution: a tiny fraction of contributions are brilliant, a modest share are adequate, and the vast majority are noise. The entire model depends on your ability to design incentive structures, filtering mechanisms, and aggregation systems that reliably surface the signal. Get this wrong and you drown in mediocrity. Get it right and you access a problem-solving capacity that no single organization can match.
A second, subtler challenge is motivation design. Contributors participate for different reasons — money, reputation, intellectual challenge, community belonging, ideological commitment — and the incentive structure must match the contributor type. Wikipedia runs on intrinsic motivation and social status. Amazon Mechanical Turk runs on micropayments. InnoCentive runs on prize purses. LEGO Ideas runs on the dream of seeing your design manufactured. Misalign the incentive and the crowd doesn't show up, or worse, it shows up with the wrong intent.
