Both e‐Manufacturing and Industry 4.0 adopt ICT as the enabling tool and emphasize the necessity of big data collection; while the former was proposed in 2000 and the later in 2012. The four key components of e‐Manufacturing are MES, SC, EES, and EC; while the four core technologies of Industry 4.0 are IoT, CPS, CMfg, and BDA. Because the cloud‐computing technology was not mature yet in 2000, e‐Manufacturing did not adopt CMfg as one of the enabling technologies.

e‐Manufacturing utilizes equipment managers in MES to collect all the process and metrology data; while Industry 4.0 applies IoT devices to collect all the data required. The technologies of IoT, CPS, and CMfg of Industry 4.0 can be applied to implement various EES functions (such as VM, PdM, and APC) of e‐Manufacturing with a more systematic and efficient fashion. The functions of SC in e‐Manufacturing can be accomplished by the CPS technology of Industry 4.0 as well. Also, BDA of Industry 4.0 can be applied to find the root causes of a yield loss for yield enhancement and yield management. Therefore, as mentioned previously, e‐Manufacturing is the predecessor of Industry 4.0. However, the function of EC in e‐Manufacturing is not considered in Industry 4.0 because EC is specific for the semiconductor industry but not the machinery industry.
