The pre-training should include four aspects. The first is to learn the correct ERP concept. Because of the difference between thoughts, it will bring completely different results; The second is to master the correct strategy and tactics of ERP implementation, because the right method can get twice the result with half the effort; The third is to understand the general management of manufacturing industry. Because to solve the problem, we must first find the root of the problem; The fourth is to learn the core functional framework of ERP. Because no matter what tools, there will be a basic working principle, no matter what you do, there will be a basic working method. Only when you are familiar with the basic principles and methods can you change your religion and draw inferences from others, instead of knowing why.
