Gushaza inzu si uburyo buhambaye gusa bwo gushaza ahantu umuntu aba, ariko kandi birashiramwo ingingo ngenderwako z’ubuhinga n’ivy’ibikorwa. Kuva ku guhitamwo ibikoresho gushika ku guhingura inyubakwa, ikintu cose co gushaza mu nzu kiragira ico gikoze ata guca ku ruhande ku kuntu ico kintu gishobora gukoreshwa, ukuntu kizomara igihe kirekire be n’ingene gifise agaciro k’ubwiza, bigatuma gishobora guhangana n’ibindi bihugu kw’isoko mpuzamakungu.
Ica mbere, ingingo ngenderwako zikora zo gushaza inzu zirimwo ugushiramwo ubuhinga bw’ibikoresho n’ubuhinga bwo gukoresha neza umubiri. Nk’akarorero, ubuhinga bwo gushaza ibikoresho vy’ibiti bushingiye ku ntumbero y’ibiti, ukuntu bikomeye be n’ukuntu bishobora guhangana n’ubukonje, mu gihe ibisharizo vy’ivyuma canke vy’ipulasitike bitegerezwa kwitwararika ukuntu bishobora guhangana n’ubushuhe, ukuntu bidashobora gusenyuka be n’ingingo mfatirwako zijanye n’ibidukikije. Mu bucuruzi mpuzamakungu, ivyo umuntu akunda biratandukanye cane mu masoko atandukanye. Nk’akarorero, amasoko y’i Buraya n’ayo muri Amerika akunda gukunda ibiti bikomeye canke ibikoresho bishobora gusubirwamwo vyemewe n’ibidukikije, mu gihe isoko ryo muri Aziya y’amajepfo yoshobora gukunda ibikoresho vy’ubuhinga bifise agaciro-bifise agaciro. Ku bw’ivyo, gutahura ivy’umubiri bikenewe n’amasoko y’intumbero ni urufunguruzo rwo kuroranirwa mu bucuruzi mpuzamakungu bw’ugushaza inzu.
Ubwa kabiri, ubuhinga bwo gushaza mu nzu bushingiye ku ngingo ngenderwako zijanye n’ubuzima kugira ngo umuntu agire ihumure n’umutekano. Nk’akarorero, ibikoresho bifasha amasofa n’ibitanda bitegerezwa kuba bihuye n’imirongo y’umubiri, mu gihe uburebure bw’ibikoresho vyo mu nzu, ameza n’intebe bitegerezwa kwakira ababikoresha bafise uburebure butandukanye. Mwene ivyo bishushanyo ntituma gusa umuntu ashobora gukoresha neza ico kintu, ariko kandi biratuma ico kintu gishobora gutandukanywa n’ibindi bihugu kw’isoko mpuzamakungu. Ikindi kandi, ingingo ngenderwako z’ubwiza zo gushaza mu nzu na zo nyene zirahambaye. Guhuza amabara, imiterere y'imiterere, n'imiterere bifise ico bikoze ku ngingo z'ugugura z'abaguzi. Amashirahamwe y’ubudandaji yo hanze arakeneye gukora ubushakashatsi bwimbitse ku bijanye n’imico kama y’amasoko ashaka gushiramwo. Nk’akarorero, isoko ryo mu Burengero rikunda uburyo bwo gushaza bwo muri Scandinavie, mu gihe isoko ryo mu Buseruko bwo Hagati ryoshobora gukunda ibintu vy’agaciro vy’ugushaza vy’inzahabu.
Mu ncamake, ingingo ngenderwako zikora mu bijanye no gushaza mu nzu zirimwo ibintu bitatu: ibikoresho, igikorwa, n’ubwiza. Abahinga mu vy’ubudandaji n’amahanga barakeneye kwihweza neza ivyo bintu kugira ngo bashobore gushitsa neza ivyo isoko mpuzamakungu risaba no kwongerera ubushobozi ibicuruzwa.
