Synectics is a creative problem-solving method developed in the 1950s that uses metaphor and analogy. It involves (1) defining the problem, (2) imaginative exploration of alternatives through metaphorical triggers, and (3) reinventing solutions. Groups are given a problem and random object, then discuss how the problem is like that object to spark new ideas. For example, a group given "making recycling habitual" and "water bottle" noted bottles are transparent, so bins could be transparent to increase understanding of the recycling process.
