As an Enterprise Business Consultant, I am frequently asked my opinion about products and solutions for my clients. Using an age old technique - Analysis of Alternatives allows me to provide an objective view point that is both a quantitative and a qualitative assessment of potential solution sets for my customers.
An Analysis of Alternatives (AoA) is an analytical comparison of the operational effectiveness, suitability, and life-cycle cost of alternatives. AcqNotes provides an overview of AoAs at https://acqnotes.com/acqnote/acquisitions/analysis-of-alternatives.
This site also provides an AoA Handbook which is based on over twenty years of analytical advice to the Air Force and other DoD agencies. It has been shaped by best practices gathered from well over two hundred AoAs and implementation observations.
