Private-collective model of innovation

Private-collective model of innovation means that people can come up with ideas in private (on their own) or collectively (working together with other people). Then, these ideas can be shared with the public, which can help to improve them further. This model helps to encourage innovation because it allows people to work together, so that they can come up with even better ideas than they could on their own.
