Ica mbere, igikorwa co guhingura ibintu. Igihe umuntu ariko arahingura, uretse kumenya geometry n’ubunini bw’ivyo bikoresho bishingiye ku mibereho y’ibikorwa n’ingene ibikoresho vy’ivyuma bikora, birakenewe kandi ko umuntu yihweza ukuntu igishushanyo gikozwe mu buryo bwo kubona ibintu n’ibiranga ibikorwa vyo gutera, ni ukuvuga ingaruka zigaragara n’ugukomera, uguhagarika umutima n’ibindi bibazo, kugira ngo umuntu yirinde canke agabanye utunenge nk’ugutandukanya, gusenyuka n’ugusenyuka kw’imiterere y’ivyo bikoresho.
Ubwa kabiri, hategerezwa kubaho uburyo bwo gutora abantu. Ni ukuvuga, hakurikijwe imiterere, uburemere n’ubunini bw’ivyo gutera, gutera ibiranga ivyuma n’ingene bikora, uhitemwo uburyo bwiza bwo gufatanya n’imiterere, uburyo bwo gukora neza, no gushinga umurongo w’ivyuma, ivyuma bikonje, ivyuma vy’ugusuka n’ugusuka. Kugira ngo ushobore gutera neza.
Ica gatatu, uburyo ibikoresho bitagira agaciro bikoreshwa mu gutera. Uburemere bw’ivyuma, ivyuma bigoramye, amavuta, umuhinduzi, umusenyi wo gutera, umusenyi, irangi n’ibindi bikoresho ntibizoshika ku rugero rwo hejuru, ivyo bikaba bizotuma habaho utunenge nk’ibipfukisho, ivyuma vy’amabuye, gushiramwo umusenyi, n’ibindi, bikaba bigira ico bikoze ku buryo bwo kugaragara be n’uburyo bw’imbere bw’ibikoresho vyo gutera imbere, kandi bizoteza ko ibikoresho vyo gutera imbere bifatwa mu bihe bikomeye. Ica kane ni igikorwa co gukora, gutegura uburyo bwo gukora neza, gutuma abakozi bagenda neza, kugira ngo uburyo bwo gukora bushizwe mu ngiro neza.
