Evaluating Project Alternatives Topics Feasibility Studies Alternatives Studies Reading Assignment Textbook – Appendix C

Introduction Analysis of Alternatives (AoA) is the analytical comparison of multiple alternatives that is completed before committing resources to finalizing and design the preferred alternative. The practice of comparing multiple alternative solutions has long been a part of engineering practice. There is, however, a natural human tendency to propose a single alternative for funding or development and justify this option rather than compare multiple options with the goal of choosing the best one. Justification is easier to do than evaluating multiple options and making a learned decision. Thus, many governmental and private agencies have found it necessary to encourage those proposing projects to use AoA.
