To determine the feasibility and effectiveness of solutions.
Musts
Requirements the solution must meet in order to be considered feasible. Musts should be measurable. A must will determine whether or not a solution is selected for implementation. If a possible solution does not meet all must criteria, it will not be considered further.
Wants
Criteria the solution should meet in order to be the best choice. Wants can be measurable or subjective. Wants determine the priority of the solutions. The more want statements that are met by the solution, the better the solution.
There is no ideal number of criteria, but a large number of criteria will take more time to analyze.
