The document discusses McKinsey's concept of "two speed IT" and how organizations can implement a two speed approach to IT delivery. It provides an example of a government organization that launched a Mode 2 delivery model to enable faster delivery of IT changes alongside its existing Mode 1 processes. The key aspects of implementing a successful two speed approach discussed are getting senior sponsorship, focusing the initial pilot on the right projects, staffing the new model with experienced people, and establishing processes to incrementally scale the new model while continuing to improve the existing model.
