Impompo yokulinganisa ikwabizwa ngokuba yimpompo yobungakanani okanye impompo yokulinganisa. Impompo yokulinganisa yimpompo ekhethekileyo yokufuduka enokuthi ihlangabezane neemfuno zeenkqubo ezahlukeneyo zobuchwepheshe ezingqongqo, inezinga lokuhamba elinokulungelelaniswa ngokuqhubekayo phakathi koluhlu lwe-0-100% kwaye isetyenziselwa ukuhambisa ulwelo (ingakumbi ulwelo oludlekayo)
Ipompo yokulinganisa luhlobo lomatshini ohambisa ulwelo kunye nesici sayo esibalaseleyo kukuba inokugcina ukuhamba rhoqo ngaphandle koxinzelelo lokukhupha. Ngompompo wokulinganisa, imisebenzi yokuhambisa, i-metering kunye nohlengahlengiso ingagqitywa ngaxeshanye kwaye ngenxa yoko, inkqubo yokuvelisa inokwenziwa lula. Ngeempompo ezininzi zokulinganisa iimitha, iindidi ezininzi zemidiya zinokufakwa kwinkqubo yetekhnoloji ngokwemilinganiselo echanekileyo kwaye emva koko ixutywe.
