Recent surveys show that managers tend to consider compliance restrictions and a lack of resources as the main obstacles to innovation. This common wisdom suggests eradicating all constraints: by getting rid of rules and boundaries, creativity, and innovative thinking will thrive. Our research, however, challenges this wisdom and suggests that managers can innovate better by embracing constraints. We reviewed 145 empirical studies on the effects of constraints on creativity and innovation, and found that individuals, teams, and organizations alike benefit from a healthy dose of constraints. It is only when the constraints become too high that they stifle creativity and innovation.
