Good ideas rarely come from one lone genius. More often they come from many people, each holding one piece. Crowdsourcing is the habit of asking them.
An old idea
In 1714 the British government offered a large prize for a practical way to find a ship's longitude at sea. It was open to anyone. The instruments that finally worked were built by John Harrison, a clockmaker, not by an established scientist.
In 1906 the statistician Francis Galton looked at a country fair where about 800 people guessed the weight of an ox. No single guess was perfect, but the middle of all the guesses was within a few pounds of the true weight. The idea became known as the wisdom of crowds.
The digital turn
The internet made asking many people cheap. Wikipedia, the Linux operating system and OpenStreetMap were all built by large, loosely connected groups. In the 2000s the word crowdsourcing was coined for the practice, and companies began using it for product ideas, customer feedback and process improvement.
Why it works
Four things make a crowd useful, and they are the same four that make it fail when they are missing:
- Different views. People with different jobs and histories notice different things.
- Scale. With enough people, the useful but unusual idea gets seen.
- Safety to speak. People say what they think when they are not exposed for saying it.
- Ownership. People who helped choose a direction are more likely to help carry it out.
Looking inward
Much of the knowledge a company needs is already inside it, in the heads of the people closest to the work. Most of it stays there, because it has no easy route out. It lives in meetings where a few people talk, or in inboxes no one reads.
Asking everyone one clear question, and letting them choose between ideas, gives that knowledge a route. It is quick for each person, and the ranking shows what the group backs.
What leaders still do
Crowdsourcing does not replace leadership. People can say what they would back. Leaders weigh what is possible: budget, timing, risk. They decide, and they explain the decision. Done well, asking widely makes leaders better informed and makes the decision easier for people to accept.
Where to start
Pick one question that matters and that you are prepared to act on. Ask it of a group big enough to be varied. Share the result and what you decide. Then see how people answer the next question.
