Managed decline is a way of making sure that a business, thing, or activity decreases in size and importance over time. When something is in managed decline, changes are made to make sure it gets smaller and less important gradually, until it eventually disappears. To make sure this happens, managers (people who are in charge of making decisions) might close some of the business's stores, or stop offering some of the things they normally provide. This way, the business can keep doing business for a little longer and it can lose less money over time.
