Chiŵerengero cha michere pakugwiritsa ntchito feteleza woyambira wamankhwala ndichokwera kwambiri, ndipo gawo la madzi ophatikizika ndi feteleza ndizochepa. Kusankhidwa kwa feteleza ndi kosagwirizana ndi sayansi. Alimi makamaka amadalira nkhani zabodza zamabizinesi posankha feteleza, ndipo zopatsa thanzi zimakhala zosakwanira.
