It clearly was important to work with project stakeholders when selecting a corridor, in order to identify possibilities and make an appropriate choice. But stakeholder involvement continues throughout the ICM project, although there can be different levels of engagement at different points in the process. The Connected Corridors project generally followed the V diagram of the systems engineering cycle as illustrated in the Federal Highway Administration's Systems Engineering Guidebook:
In this framework, stakeholder involvement is:
- Very high early in the project during concept exploration and system planning
- High as the system is progressively more defined and again later during system acceptance and validation
- Less so at the bottom of the V when system components are being designed, built, and tested
This general approach can, of course, be adjusted over time to meet the evolving needs of the project.
