;"INITIAL MATRIX";"FILLING PROCESS"  ;"Pre-filled matrix";"Empty matrix";"Filling in consensus";"Full individual filling";"Partial individual filling";"Individual filling + consensus round" Description;"Based on a pre-filled matrix, experts adjust the pre-filled scores";"Each score has to be defined";"Use a workshop with all experts to discuss each score and forge a final consensus score";"Each expert fills in the matrix";"Each expert completes the part of the matrix tied to their expertise";"After an individual fill-in, a “second round” discussing the scores with high variance" Resources;"Preliminary studies, bibliography, pre-existing matrices";None;"Workshop, trained facilitators ";"Preparatory workshop";"Preparatory workshop";"Technical logistic" Time;"Variable depending on data sources availability"; None;"Long time with all experts depending on size of the matrix and number of experts";"½ day workshop + 30 s to 1 min/cell";"½ day workshop + 0.5 min/cell ";"½ day workshop + 0.5/1 min/cell + 1 day consensus workshop." Pros;"Quicker than  with an empty matrix";"No influence- analytical and statistical benefits";"Consensus validation -Collective intelligence -Capacity building -Most of the work done during the workshop";"No interaction biases - Easy to organise - Statistical power";"Experts only score in their field of expertise -Quick";"All expertise -sets are taken into account - Analytical and statistical benefits -Consensus validation" Cons;"Experts are influenced by the pre-filled scoresDifficult to differentiate whether pre-filled scores left unchanged because the expert did notthink he/she had the knowledge to credibly change them or because he/she agreed with them- Variability and reliability statistics meaningless";Time-intensive;" All Experts in attendance at the workshop Long workshop that needs well-trained facilitators Power and personality influence biases Difficult to organise (time availability of the Experts)";"Long for the Experts  Less expert input due to the time it takes to fill in the whole matrix Individual fill-in may introduce personal understanding biases";"Needs 10–15 people per type of expertise =  lot of people Difficult to have the same number of experts per score More complex for statistical analysis";"All Experts must be present at the consensus workshop Difficult to organie (time availability of the Experts)"
