Can you provide a crosswalk to compare legacy milestones and new process milestones; e.g., the Alternatives Milestone is between
F2 and F3?
We have deliberately avoided an explicit crosswalk between the legacy milestones and the new feasibility study process milestones
because these new milestones are very different than our previous milestone structure. The new process milestone are a measure of
an agreement that we make as an agency, rather than getting to a certain point and checking it off vertical team engagement
throughout the study and documentation of decisions are key elements of the milestones and the process. Further, by marking a
decision point rather than briefing or task, the new feasibility study milestones are meant to underline the need to invest study
resources in making the decision at hand, rather than in developing duplicative read-aheads, pre-briefings, and briefings that have
come to characterize the legacy milestones.
