Irobhothi elibumba umjovo livamise ukuhlanganisa isistimu yokusebenza, isistimu yokushayela, kanye nesistimu yokulawula. Amasistimu okubulala kanye nokushayela aklanyelwe ukwenza imisebenzi evamile yengalo, esebenzisa amandla omoya noma amanzi ukuze ashayele izingxenye zemishini futhi afeze umsebenzi wokukha. Uhlelo lokulawula lulawula uhlelo lokushayela, luqinisekisa ukuthi uhlelo lokubulala lusebenza ngokwenqubo enqunywe kusengaphambili. Ukuthatha uhlelo olulula lokulawula irobhothi njengesibonelo:
-Isixhumi esibonakalayo somshini ←→ Ukuvula Umshini Wokubumba Umjovo Ukuvula Isignali Ephelele ←→ Isilawuli Esincane ←→ Isignali Yerobhothi Yomshini Wokubumba Umjovo ←→ Amasignali Ahlukahlukene Amavaluvu ←→ Isilinda Sokuvula
Umsebenzisi usebenza-ngokusebenzisa isixhumi esibonakalayo somshini womuntu. Lapho irobhothi lithola isignali esebenzisekayo emshinini wokubumba umjovo, linqamula isignali yokuvala isikhunta somshini wokubumba ukuze kuqinisekiswe ukuphepha kokucosha umkhiqizo. Ngemva kokucosha umkhiqizo, irobhothi liqala kabusha ukusebenza komshini wokubumba umjovo. Inselele yokuklama yesistimu yokulawula ilele ebudlelwaneni bokusebenzisana phakathi kwerobhothi nomshini wokubumba umjovo. Ngaphansi komyalo wesistimu yokulawula, irobhothi liqedela izenzo ezihlukahlukene ngokuya ngenqubo yomsebenzi enqunywe kusengaphambili, ngaleyo ndlela lisusa umjovo-umkhiqizo obunjiwe esikhunjeni futhi liwudlulisela endaweni emisiwe noma inqubo yokukhiqiza elandelayo. Lapho uklama, isistimu yokulawula kufanele inqunywe ngokusekelwe ekusebenzeni komshini wokubumba umjovo, izimo zokusebenza kanye nezidingo zerobhothi, kanye nokuma nesisindo somkhiqizo.
