Enterprise Resource System (ERS) is a business philosophy that focuses on managing and optimizing the use of resources in a company. It involves identifying and allocating resources where they can best be leveraged to achieve an organization’s objectives. These resources can include human capital, physical resources like equipment and land, financial capital, natural resources, and intellectual resources such as knowledge and technology. By using ERS, companies are better equipped to make sound decisions, become more efficient, and maximize their profits.
