McDonald’s features several products on their menu that are permanent and do not change. Examples of this include their basic hamburger and cheeseburger, the Big Mac and the Quarter Pounder. After the initial development, these items remain on the menu for extended periods of time without undergoing significant changes. This strategy ensures that there is always something familiar for consumers on the menu. In addition to its permanent product offerings, McDonald’s regularly develops temporary products. The McRib, for example, is a product that is offered only seasonally. The Big Ocean burger is an example of a burger that was developed as a temporary product, offered only for a few months in 2007. The purpose of this product development strategy is to give customers something new to experience on each visit and to experiment with new items that may become permanent.
