Menu Engineering Matrix
Sorts a menu item into a Star, Plowhorse, Puzzle, or Dog (Kasavana-Smith) from its contribution-margin dollars and popularity share against the menu average. Classifies on margin dollars, not food-cost percent -- the decision that drives what to promote, reprice, or cut.
Formula and source
contribution_margin = price - food_cost; popularity_share = units_sold / total_units; popularity_threshold = (1 / item_count) x 0.70; quadrant from margin >= average and share >= threshold.
Kasavana & Smith menu-engineering model, by name.
