Subjective Rating and Ranking

Definition of Subjective Rating and Ranking:

This is a very common and easy to use matrix where the possible causes generated through brainstorming or other group activities are rated by a team of experts first individually. For convenience and clarity , the rating is done as 0 (No Significance ), 1 (Little Significance ) , 3 (May be significant ) and 9 (Highly significant). Once the entire team has rated the possible causes, they are grouped and ranked (normally by using median) and higher ranked reasons are worked on priority. This serves a good tool if the team consists of members having very good knowledge of the subject.
