McDonald's also began to fail consistently with its new product introductions, such as the low-fat Mclean Deluxe and Arch Deluxe burgers, both of which were meant to appeal to adults. It did no better with its attempts to diversify beyond burgers, often because of problems with the Product development process. Consultant Michael Seid, who managesa franchise consulting firm in West Hartford, pointed out that McDonald's offered a pizza that didn't fit through the drive-through window and salad shakers that were packed so tightly that dressing couldn't flow through them.
