Use evaluation and decision-making tools when you want to narrow a group of choices to the best one, or when you want to evaluate how well you’ve done something. This includes evaluating project results.
Decision matrix: Evaluates and prioritizes a list of options, using pre-determined weighted criteria.
Multivoting: Narrows a large list of possibilities to a smaller list of the top priorities or to a final selection; allows an item that is favored by all, but not the top choice of any, to rise to the top.
