The story of Bian Que's three brothers embodies three modes: pre-control, in-process control and post-control. Although each mode is of great significance for enterprises to maintain good production and operation order, prevent major accidents and deal with emergencies. But it is not difficult to judge which control mode can control risks with the least investment.

Peter drucker, the "father of modern management", said in his book Effective Managers, "A well-managed factory will always be boring if there are no exciting events." Management enterprises must learn from Bian Que's thought, plan ahead, plan ahead, and nip the factors that may bring risks and hidden dangers in the bud. It is necessary to see the micro-knowledge, see the big from the small, accurately predict the development momentum and direction of things, intervene and control in advance, and make them develop in a benign direction. It is necessary to build a complete risk control mechanism and build an intrinsically safe enterprise.
