Yimodeli apho inkqubo ichazwa njengenethwekhi apho indibano-malungu nganye imele izibonelelo zenkonzo ezinikezela ngohlobo olunikeweyo lwenkonzo kunye nomngcelele wezinto ezikhoyo ezilindele ukuncedwa; umzekelo, imodeli echaza inethwekhi yokuthumela ngolwandle kunye nezibonelelo zasechwebeni apho iinqanawa kumele zenze umngcelele ukuze zikwazi ukothula imithwalo yazo.
