You have been assigned to a project in which the objectives are to expand three miles of the north-to-south highway through your city by two lanes in each direction. You are interested in implementing a new project process called Design-Build in order to speed up the project schedule. The idea is that the construction team will work on the first mile of the highway reconstruction at the same time the design team is coming up with plans for the third mile of the reconstruction rather than completing all design before any construction begins. This is an example of which of the following?

A. Managing the projects as a program B. An iterative phase-to-phase relationship C. Progressive elaboration D. Fast tracking
