Njengoba kunikezwe lesi sigaba esiyisihluthulelo ngomlando wendlela "yezizathu ezinhlanu", yayiyini inhloso yokuqala yokubuza "izizathu ezinhlanu"?
Context:Le ndlela yasungulwa ekuqaleni nguSakichi Toyoda futhi yasetshenziswa ngaphakathi kweToyota Motor Corporation ngesikhathi sokuvela kwezindlela zayo zokukhiqiza. Kuyingxenye ebalulekile yokuqeqeshwa ekuxazululeni izinkinga, enikezwa njengengxenye yokungeniswa ohlelweni lokukhiqiza lweToyota. Umklami weToyota Production System, uTaiichi Ohno, wachaza indlela yezizathu ezinhlanu ngokuthi "isisekelo sendlela yesayensi kaToyota ngokuphindaphinda ukuthi kungani izikhathi ezinhlanu uhlobo lwenkinga kanye nekhambi layo kuba sobala". Leli thuluzi selisetshenziswe kabanzi ngaphandle kweToyota, futhi manje selisetshenziswa ngaphakathi kweKaizen, ukukhiqiza okulula, ukwakhiwa okulula kanye neSix Sigma. Izizathu ezinhlanu ekuqaleni zasungulwa ukuze kuqondwe ukuthi kungani kudingeka izici ezintsha zomkhiqizo noma izindlela zokukhiqiza, futhi azenzelwanga ukuhlaziywa kwezimbangela eziyisisekelo.
Inhloso yokuqala yokubuza 'izizathu ezinhlanu' kwakuwukuqonda ukuthi kungani izici ezintsha zomkhiqizo noma izindlela zokukhiqiza zazidingeka emikhubeni yokukhiqiza yeToyota.
