Nangona ibonakala ngathi "yinto encinci" kwimveliso yemizi-mveliso, Izixhobo zokuvala ubushushu Iikhava ngokwenene "zizinto ezibalulekileyo" ezinxulumene nokugcinwa kwamandla, ukunciphisa ukusetyenziswa, imveliso ekhuselekileyo, kunye nomgangatho wemveliso. Azincedi nje kuphela amashishini ukunciphisa iindleko zokusebenza kunye nokunciphisa iingozi zokhuseleko kodwa zikwanegalelo ekufezekiseni uphuhliso oluluhlaza nolunekhabhoni ephantsi kwicandelo lemizi-mveliso. Ngokuchasene notshintsho lwangoku lwemizi-mveliso kunye nokuphuculwa kwayo, ukukhetha iikhava zokukhusela izixhobo ezifanelekileyo nezisemgangathweni kuye kwaba yindlela ebalulekileyo kumashishini ukuphucula ukhuphiswano lwawo oluphambili. Kwixesha elizayo, ngobuchule obuqhubekayo bobuchwepheshe kunye nobubanzi obandayo beemeko zesicelo, iikhava zokukhusela izixhobo ziya kudlala indima ebaluleke ngakumbi kwimveliso yemizi-mveliso, zibonelela ngenkxaso eqinileyo kuphuhliso oluphezulu lwamashishini ahlukeneyo.
