Xa ukhetha umbhobho we-ERW wokusila, imiba ekufuneka iqwalaselwe ibandakanya umthamo wemveliso, uluhlu lwedayamitha yombhobho, ukuhambelana kwezinto, inqanaba lokuzenzekelayo, kunye nenkxaso yokuthengisa emva kokuthengisa. Okokuqala, umthamo wemveliso ngumba ophambili omisela ukuba mingaphi imibhobho yokusila enokuvelisa ngexesha elithile. Ukukhetha ilitye lokusila elinomthamo wemveliso onokuhlangabezana neemfuno zakho ngaphandle kokwandiswa okugqithisileyo kubalulekile ukuqinisekisa ukusebenza kakuhle kwemveliso kunye nolawulo lweendleko kuluhlu olwamkelekileyo.
