Iyini le ndlela yokuphatha iphrojekthi enezinyathelo eziningi ezihlukene?
Context:Kunezigaba ezinhlanu zomjikelezo wokuphila kwephrojekthi; ezaziwa ngokuthi amaqembu enqubo. Iqembu ngalinye lenqubo limelela uchungechunge lwezinqubo ezihlobene ukuze kuphathwe umsebenzi ngokusebenzisa uchungechunge lwezinyathelo ezihlukile okufanele ziphothulwe. Lolu hlobo lwendlela yephrojekthi luvame ukubizwa ngokuthi "ngokwesiko" noma "i-waterfall". Amaqembu ezinqubo ezinhlanu yilezi:  Izigaba ezivamile zokuthuthukiswa komsebenzi wobunjiniyela Ukuqala Ukuhlela Ukwenza Ukuqapha Nokulawula Ukuvalwa  Ezinye izimboni zingase zisebenzise ukuhluka kwalezi zigaba zephrojekthi futhi zibize kabusha ukuze zihambisane kangcono nenhlangano. Ngokwesibonelo, lapho kusetshenzwa ekwakhiweni nasekwakhiweni kwezitini nodaka, amaphrojekthi ngokuvamile ayodlula ezigabeni ezinjengokuhlela kusengaphambili, ukwakhiwa komqondo, ukwakhiwa kwesikimu, ukuthuthukiswa komklamo, imidwebo yokwakha (noma imibhalo yenkontileka), nokuphathwa kokwakhiwa.  Nakuba indlela ehlelwe ngezigaba isebenza kahle kumaphrojekthi amancane, achazwe kahle, ngokuvamile ibangela inselele noma ukwehluleka kumaphrojekthi amakhulu, noma lawo ayinkimbinkimbi kakhulu noma anezinto eziningi ezingacacile, izinkinga nezingozi
Indlela yokwehla kwamanzi, ngezinye izikhathi ebizwa ngokuthi yendabuko, iyindlela yokuphathwa kwephrojekthi enochungechunge lwezinqubo ezihlobene.
