Systems and methods for semiconductor fabrication management. A processing unit receives an engineering change request (ECR) comprising information regarding new engineering for a wafer lot, generates an ECR reminder comprising information regarding the ECR request, transmits the ECR reminder to a client operator through a communication device, receives a reply corresponding to the ECR reminder, determines a reply result indicating whether the ECR is accepted by detecting the reply, and transmits the reply result to a manufacturing execution system (MES).
