What are the 4 basic types of innovation?

The four basic types of innovation are incremental, disruptive, architectural, and radical innovation. Incremental innovation involves small, gradual improvements to existing products or processes. Disruptive innovation creates new markets by introducing products that initially serve a niche but eventually displace established competitors. Architectural innovation changes the way components of a system interact, while radical innovation introduces groundbreaking ideas or technologies that significantly alter industries.
