Indlela yokugweba umgangatho womgca wendibano yocweyo?
Undoqo kukuthintela iimpazamo ukuba zenzeke.
Yintoni "ubungqina bempazamo"?
I-Poka-YOKE ibizwa ngokuba yi-POKA-YOKE ngesiJapan kunye noBungqina bempazamo okanye ubungqina beSidenge ngesiNgesi.
Kutheni kukhankanywa isiJapan apha? Abahlobo abasebenza kwishishini leemoto okanye kwishishini lemveliso kufuneka bazi okanye beve ngeToyota Production System (TPS) yeToyota Motor Corporation.
Ingcamango ye-POKA-YOKE yaqalwa nguShingo Shingo, ingcali yolawulo lwekhwalithi yaseJapan kunye nomsunguli we-TOYOTA Production System, kwaye yaphuhliswa ibe sisixhobo sokufezekisa i-zero defects kwaye ekugqibeleni isuse ukuhlolwa komgangatho.
Ngokoqobo, i-poka-yoke ithetha ukuthintela iimpazamo ukuba zenzeke. Ukuqonda ngokwenene i-poka-yoke, masiqale sijonge "iimpazamo" kwaye kutheni zisenzeka.
"Iimpazamo" zibangela ukuphambuka kwizinto ezilindelweyo, ezinokuthi ekugqibeleni zikhokelele kwiziphene, kwaye inxalenye enkulu yesizathu kukuba abantu abakhathali, abakho zingqondweni, njl.
Kwishishini lemveliso, eyona nkxalabo yethu inkulu kukwenzeka kweziphene zemveliso. “Umntu, umatshini, izinto, indlela, indawo esingqongileyo” zonke zinokuba negalelo kwiziphene.
Iimpazamo zabantu azinakuphepheka yaye azinakuphetshwa ngokupheleleyo. Ezi mpazamo zinokuchaphazela oomatshini, izixhobo, iindlela, okusingqongileyo, kunye nemilinganiselo, njengoko iimvakalelo zabantu azihlali zizinzile kwaye zinokukhokelela kwiimpazamo ezifana nokusebenzisa izinto ezingalunganga.
Ngenxa yoko, ingcamango "yokuthintela iimpazamo" yavela, igxininise kakhulu ekulweni neempazamo zabantu. Ngokuqhelekileyo asixoxi ngezixhobo kunye neempazamo eziphathekayo kwimeko efanayo.
