What are the disadvantages of using grid analysis to make decisions?

Grid analysis is best used when a decision needs to consider multiple outcomes and different criteria. The format of this method however, can provide bias to a certain outcome. The process is only as good as the quality of information placed within the grid including the scoring. Once a factor is graded or placed subjectively, objectivity is compromised in this method. Also, this method keeps decision making strictly in a rational manner. But, it is considered unhealthy to be linear in decision making and one-sided. It is best to base decisions from a rational and take emotions into account as well.
