Irreversibility of a measurement procedure

It is shown in the paper that any measurement procedure possesses inherent generic property of irreversibility. The property consists in impossibility of a process where a transition is possible from a finite state of a system to its initial state through the same states but in reverse order. The irreversibility is accompanied by property of sequentiality that means multistage character of a measurement. Awareness of these properties can provide some useful ways and tools for development of new measurement methods.
