Simple vs weighted average
WebbThe weighted decision matrix is a powerful quantitative technique. It evaluates a set of choices (for example, ideas or projects) against a set of criteria you need to take into account. It also is known as the "prioritization matrix" or "weighted scoring model". No need to get confused.
