Can optimization begin before the Agency Decision Milestone?
Yes, but it must not inhibit the formulation and evaluation process by prematurely focusing the planning work on a narrow set of
options. The first objective of planning is to demonstrate that the recommended course of action compares favorably to other
courses of action on the basis of benefits, impacts, and costs. This is the work done by the Project Delivery Team before the
Tentatively Selected Plan Milestone. Some intuitive optimization (judgment) will occur as measures are combined to create
alternatives. The scale of each measure must be specified, and this scale is initially based on a judgment of what would be effective.
