Amazon SOP is the capitalization of the first letters of the three words Standard Operating Procedure, that is, the standard operating procedure, which describes the standard operating steps and requirements of a certain event in a unified format to guide and standardize daily work.

SOP is a standard operating procedure. The so-called standard here has the concept of optimization, that is, not all operating procedures written casually can be called SOP, but must be the most optimized operating procedure design that can be achieved under current conditions after continuous practice and summary. To put it more simply, the so-called standard is to refine, quantify and optimize the relevant operating steps as much as possible. The degree of refinement, quantification and optimization is that everyone can understand it under normal conditions without any ambiguity.
