The alternatives analysis phase compares all alternatives with the baseline condition to facilitate an understanding of potential impacts and to begin negotiating and creating new alternatives more compatible with the multiple objectives of the many parties. Probably the biggest mistake the interagency group could make at this point is to choose one alternative from a group of poor alternatives. It is far better to create new alternatives, learning as you go. When complete, this phase results in a comprehensive array of alternatives, each quantitatively described. Data and models are never complete or perfect.

The methodology is not fixed. It is open-ended and imaginative. Flexible, mutually beneficial, negotiated solutions are encouraged.
