The paper presents a procedure enabling to reveal and systematize the techniques of purposeful process realization by classifying verbally described concept reflecting this process per general/particular principle. The focus is made on “generic” methods revelation mechanism. The procedure is exemplified in the revealing general methods of quantities transformation: the process underlying many other processes including measurement, inspection, and control. The picture of the upper classification levels of general transformation methods is drawn up and can be further developed with reference to specific types of this process as well as to other relevant processes.
