Individuals who disobey orders from senior management to stop working on new ideas and continue pursuing innovation are demonstrating creative deviance. While top-down decision making works well for highly innovative companies like Apple, encouraging too much creative deviance can be dangerous if control is lost over the group or if employees believe they have authority to act without oversight. Apple's hierarchical structure is actually quite simple and responsibility is placed on individuals, and cross-functional teams meet continuously, allowing for innovation within the hierarchy. However, over-reliance on a single individual for decision making can lead to missed market changes or failures if their vision is flawed.
