Ngenxa yokuthi ama-oda afakwa ngqo efektri, izinzuzo zabadayisi ziyasuswa futhi izilinganiso zakhiwe ngokusobala kusukela kwisisindo sezinto, ukuhloma kanye nenkokhelo yempahla. Intengo iqinisekiswa esigabeni sokulinganisa, futhi amasampula amahhala ayatholakala ukuze ahlolwe ngaphambi kokuba kufakwe i-oda elikhulu.
Yimaphi amazwe enithumela kuwo ikhebula le-YJV, futhi lipakishwa kanjani?
Ukuthunyelwa okuvamile kuya ezimakethe kulo lonke elaseNingizimu-mpumalanga ye-Asia nase-Afrika, kuhlanganise namaphrojekthi okwakha, ezimboni kanye namaphrojekthi wamandla avuselelekayo. Izintambo zigoqwa emiphongolweni yokhuni noma yensimbi elinganiswe ngamakhonteyina ajwayelekile, iziphetho zazo zivikelekile futhi kubhalwe ngokucacile ubude, usayizi nenombolo yeqembu. Imibhalo yokuthumela ngaphandle njengohlu lwempahla, ama-invoyisi, izitifiketi zemvelaphi kanye nemibiko yokuhlolwa ilungiselelwa ukuhambisana nezidingo zendawo ekuyiwa kuyo. Ukuthutha kuhlelwa ngokubambisana nama-ejenti bokuthutha ukuze izikhathi zokuhamba zihlale zibikezelwa.
Yisiphi isikhathi sokulinda okufanele ngisilindele uma ngioda ikhebula le-YJV?
Isikhathi sokuhola sincike kubuningi, inhlanganisela yesigaba esiphambanayo nokuthi i-oda liyijwayelekile noma lenziwe ngokwezifiso. Izinto zekhathalogi ezinosayizi abajwayelekile zihamba ngokushesha, kuyilapho imikhiqizo ehlomile, ekwazi ukumelana nomlilo noma yobude obukhethekile idinga isikhathi esengeziwe sokukhiqiza nokuhlola. Isikhathi sokuhola esiqinisekisiwe sishiwo esivumelwaneni se-oda ukuze izinhlelo zesiza zikwazi ukuhlelwa ngaso. Ama-oda aphindwayo alandela ukucaciswa okugunyaziwe okufanayo, okuvamise ukunciphisa kokubili ukukhiqiza nokuhlola.
