An ERP system allows an organization to integrate applications across business functions like accounting, manufacturing, sales, and marketing. Implementing an ERP system is a complex process that typically involves planning, configuring, and deploying the system over several phases. Key benefits of ERP implementation include improved information accuracy and availability, enhanced reporting, cost savings, and better customer service. However, ERP projects also face challenges such as inadequate requirements definition, resistance to change, unrealistic timelines, and poor communication. Careful planning is required to successfully implement an ERP system.
