Does the new layout have a better score compared to the initial layout? Answer: This question is about CRAFT method, used to evaluate current design but not to create new design. Our objective is to figure out distance table, which shows the distance between all the department pairs using the rectilinear distance of their center and use this table to multiply the From-to chart, then we get the Flow*Distance Table. Then we sum up across the rows (NOT COLUMNS!) and then sum all the summations to get the final score. The layout with LOWER score is BETTER (contrary to ALDEP).
