Method, computer program, and computer readable medium for defining stage time nodes of operation process

Method, computer program, and computer readable medium for defining the stage time node of an operation process. The method includes: providing at least one object recording element in an operation process; presetting a plurality of sampling criteria in sequence in the operation process; when a target object meets any one of the sampling criteria in the operation process, the at least one object recording element recording a first message of the target object and defining the acquisition time as a first time node; when the target object meets another one of the sampling criteria, the at least one recording element recording a second message of the target object and defining the acquisition time as a second time node; calculating a time difference value between the first time node and the second time node; comparing the time difference value with a comparison value to evaluate an operation efficiency of the target object in the operation process, as a basis of precise operation.
