Question

Modelo, S.A., is considering three providers of automated visual inspection systems for their packaging needs. A team of manufacturing engineers, production managers, and process engineers has developed the following list of criteria and assigned them ratings on a scale of 1 (completely unimportant) to 5 (critical). This team has also rated the candidate products on each of these dimensions using a scale of 1 (poor) to 5 (excellent). Which provider should they choose and what caveats, if any, should go with their recommendation?
