Maitiro Ekuongorora Vatengesi, Mari Yose, uye Kutumirwa Kwebasa
Kusarudza hardware chaiyo chikamu chimwe chete chemuenzaniso; kushanda pamwe chete nemugadziri ane hunyanzvi kunotungamira kubudirira kwenguva refu kwekushandiswa kwayo. Kuongorora kwakakwana kwehunyanzvi hwemutengesi, Total Cost of Ownership (TCO), uye rutsigiro mushure mekuiswa kunoita kuti nharembozha dzakasarudzwa dzisaputika dzive dzakachengeteka uye dzinoshanda.
Ndezvipi zvinodiwa pakutsvaga rubatsiro zvinobatsira pakuziva vagadziri vanokwanisa
Vagadziri vane hunyanzvi hwekushandisa michina isingaputike vanofanira kuratidza hunyanzvi hwekugadzira michina.chitupa cheISO 9001 chakajairwa, vatengi vanofanira kutsvaga vatengesi vane ongororo chaiyo yekugadzira zvinhu.

Vatengi vanofanirawo kuongorora kubatanidzwa kwemugadziri. Vatengesi vanogadzira mabhodhi avo makuru uye vanoisa machira avo ekuchengetedza vanowanzopa kutonga kwemhando yepamusoro uye hupenyu hwezvigadzirwa hurefu kana zvichienzaniswa nevanobatanidza vanongorongedza zvinhu zvevamwe. Kukumbira zvidzidzo zvekushandiswa munzvimbo dzakaoma zvakafanana kunopa humbowo hunooneka hwehunyanzvi hwemutengesi.
Vatengi vanofanira kuenzanisa sei nguva dzekutengesa, zvikamu zvekuchengetedza, uye garandi
Nguva dzekushanda kweprojekiti chinhu chakakosha pakuronga hurongwa hweprojekiti. Mafoni akajairika asingapindi kuputika anofanira kunge aine nguva yekushanda kweprojekiti yemavhiki mana kusvika masere, nepo magadzirirwo eSIP akagadzirwa zvakanaka ane mabhekoni akabatanidzwa anogona kusvika mavhiki gumi nemaviri kusvika gumi nematanhatu.
