Big companies are much better at incremental innovation than they are at radical innovation. That’s as true now as it was 20 years ago, despite countless programs aimed at strengthening innovation capabilities. To understand why, researchers at Rensselaer Polytechnic Institute studied 21 large companies’ efforts to build a capability for breakthrough innovations over several years. They found that even though companies pay lip service to innovation, most fail to provide the formal structure and support that programs need to succeed, such as an autonomous organization, processes tailored for highly uncertain work, and well-designed metrics.
