Ibhokisi yokugawula esebenziswe ngokwezintambo zesitayini esihlaziyo isetshenziselwa ngokwezintambo zesitayini ezisemgibeni, ezinamandla angaphezu kwezinye zezitayini zokuhlanza nokuhluza. Isidingo sakhe esikhulu kuyokugcina izinhlobo zezinto zokusebenza zokuphathwa (njengamabhreaka wezindlela, amabhokisi, amabhokisi abaphathi, njll) kusukela emsebenzini wokuhlatshelwa kwezindlu noma ukubulawa ngamagazi amabomvu noma umlotha. Isitayini esitayini sithola ukuthi kungaba khona ukuphepha nokuhlela okuhle kwezinhlobo zokugawula, okwenza kube nomthelela wokuthandwa kwemvelo yendustri. Kuyatholakala kubalulekile kubalulekile kwezindustries ezahlukene njengoba ziyaphathwa, izinhlelo zokuthengisa izinhlelo, njll.
