Kuyini ukusatshalaliswa okungenzeka?
Context:Emfundisweni yokungenzeka kanye nezibalo, ukusatshalaliswa kokungenzeka kungumsebenzi wezibalo onikeza amathuba okwenzeka kwemiphumela ehlukene engaba khona yokuhlolwa. Kuyincazelo yezibalo yesimo esingahleliwe ngokuya ngesikhala saso sesampula kanye namathuba ezenzakalo (amaqoqo amancane esikhala sesampula).  Ngokwesibonelo, uma i-X isetshenziselwa ukubonisa umphumela wokuphonsa uhlamvu lwemali ("ukuhlolwa"), khona-ke ukusatshalaliswa kokungenzeka kwe-X kuzothatha inani u-0.5 (1 ku-2 noma 1/2) ku-X = amakhanda, no-0.5 ku-X = imisila (kucatshangwa ukuthi uhlamvu lwemali luhle). Izibonelo zezenzakalo ezingahleliwe zihlanganisa izimo zezulu ngosuku oluthile lwesikhathi esizayo, ukuphakama komuntu okhethwe ngokungahleliwe, ingxenye yabafundi besilisa esikoleni, imiphumela yocwaningo oluzokwenziwa, njll.
Ukusatshalaliswa okungenzeka ukusatshalaliswa kwemiphumela ehlukene ngokusekelwe enanini elibonakalayo lezikhathi umphumela ngamunye ozokwenzeka ngazo.
