Kutheni umthengisi kufuneka acele idatha yemeko yokusebenza?
Kuba iimeko zokusebenza zizo ezigqiba ngezinto ezisetyenzisiweyo, ubungakanani, ukugqitywa, ukulingana kwekheji, kunye nexesha eliza kusetyenziswa. Umthengisi ongaceli idatha yemeko yokusebenza ucaphula inombolo yenxalenye, hayi inkcazo. Kwizindlu zeengxowa zemizi-mveliso, idatha yemeko yokusebenza (ubushushu obuqhubekayo, uhlobo lothuli, ukwakheka kwegesi, umthamo womoya, indlela yokucoca, kunye nomzobo wekheji) yeyona nto ibalulekileyo kuphononongo lobunjineli, kwaye umthengisi owujonga njengesiqhelo wenza umsebenzi oxhasa inkqubo yokubuyisela iingxowa ixesha elide.
Ngaba abathengi kufuneka bakhethe ixabiso eliphantsi lengxowa yesihluzo?
Hayi. Ixabiso eliphantsi lidla ngokuba yixabiso elingabandakanyi uphononongo lwemeko yokusebenza, ukuqinisekiswa kwezinto, ukulingana kwekheji, ixesha lokunikezelwa kwempahla ngokuchasene nomlinganiselo womyalelo, okanye indlela emva kokuthengiswa. Ixabiso elishiya ezi zinto alifanisi nexabiso elifana nexabiso elibandakanya zona. Umthengi kufuneka athelekise ixabiso elikwinqanaba leenkcukacha ezipheleleyo, hayi ixabiso leyunithi, kuba ixabiso lengxowa engalinganiyo, izinto ezingalunganga, okanye ukuhanjiswa okungahambanga kakuhle kuphezulu kunokonga kwixabiso leyunithi.
Ngaba umthengisi weengxowa zesihluzi zokuqokelela uthuli angaqinisekisa ukuba ziyathotyelwa iigesi ezikhutshwayo?
Hayi. Umthengisi unokuxhasa ukukhethwa kwezinto, uphononongo lweenkcukacha, kunye nonxibelelwano lwemveliso, kodwa ukuthotyelwa kokukhutshwa kothuli kuxhomekeke kwinkqubo epheleleyo yokuqokelela uthuli, iimeko zokusebenza, ishedyuli yokugcinwa, kunye neemfuno zomthetho zasekuhlaleni. Umthengisi oqinisekisa ukuthotyelwa kokukhutshwa kothuli wenza ibango elingaphaya kwengxowa ngokwayo. Ingxowa yinxalenye enye yenkqubo, kwaye iziphumo zenkqubo zixhomekeke kwinkqubo iyonke.
