Business process reengineering is a way to make businesses work more efficiently. It's like taking apart a machine and putting it back together in a way that makes it run faster and better. Companies look at their processes (such as making products or dealing with customers) and figure out ways to improve them. This might mean cutting out steps, automating things, or working together in a different way. This way, businesses are able to get more done in less time and with fewer resources, so they can save money and be more successful.
