Amaketango kanye{0}}nezindandatho ezilengayo ezimise U-U kuyizinto eziwumshini ezihlukile ngokuma, ukusetshenziswa, kanye nokusebenza.
1. Umumo: Amaketanga ngokuvamile agotshwa abe u-U-umumo ukuze kuzuzwe imisebenzi ethile yokuxhumana. Iringi yokulenga engu-U{3}, ngakolunye uhlangothi, isivele imise u-U{4}}futhi ixhunywe kuzo zombili iziphetho ngamabhawudi, amantongomane, amawasha, nezinye izingxenye zokuxhuma.
2. Isicelo: Amaketanga ajwayele ukusetshenziselwa ukuphakamisa imisebenzi njengezingxenye zokuxhuma zemishini yokuphakamisa. Iringi yokulenga engu-U{2}isetshenziswa kakhulukazi njengethuluzi lasemhlabeni wonke emugqeni, enezinhlobonhlobo zezinhlelo zokusebenza, futhi ingasetshenziswa yodwa noma ngochungechunge.
3. Ukusebenza: -indandatho yokulenga emise okwe-U iwuhlobo lwezingxenyekazi zekhompuyutha zikalayini ezivame ukusetshenziselwa ukuxhuma izintambo zesivikelo noma imicu yensimbi enokulungiswa kombhoshongo, kusetshenziswa izikhonkwane, izimbobo zamehlo, namabhawudi ukuze kuxhunywe. Futhi ibhande elikhiphekayo alinalo lolu hlelo lokusebenza.
Sekukonke, amaketango kanye{0}}namaringi alengayo amise oku-U kuyizingxenye eziwumshini, kodwa anomehluko othile ekubumbeni, ekusetshenzisweni nasekusebenzeni.
