A Khiav Chart yog ib qho yooj yim daim duab uas qhia cov ntaub ntawv muaj nuj nqis nyob rau hauv ib lub sij hawm ib ntus (qhov kev txiav txim uas cov ntaub ntawv raug generated). A Khiav Chart tuaj yeem pab tau rau kev txheeb xyuas cov kev hloov pauv thiab cov qauv. Piv txwv: Tus thawj saib xyuas ntawm lub chaw pabcuam cov neeg siv khoom sau cov ntaub ntawv ntawm cov ntawv tsis txaus siab uas tau foob txhua lub hlis.

Hais txog qhov no, daim ntawv qhia khiav qhia li cas?

A khiav daim ntawv qhia yog kab daim duab ntawm cov ntaub ntawv npaj rau lub sijhawm. Los ntawm kev sau thiab sau cov ntaub ntawv nyob rau lub sijhawm, koj tuaj yeem pom cov qauv lossis cov qauv hauv cov txheej txheem. Vim lawv ua tsis siv cov kev txwv, khiav kab kos tsis tuaj yeem qhia koj yog tias tus txheej txheem ruaj khov. Txawm li cas los xij, lawv tuaj yeem ua tau ua yeeb yam koj yuav ua li cas cov txheej txheem khiav.

Kuj Paub, daim ntawv qhia khiav thiab tswj daim ntawv yog dab tsi? A khiav daim ntawv qhia yog qhov yooj yim tshaj ntawm kab kos . A khiav daim ntawv qhia tuaj yeem pab koj pom qhov nce thiab nqis zuj zus thiab nws tuaj yeem qhia koj cov duab dav dav ntawm cov txheej txheem. A tswj daim ntawv qhia kuj npaj ib kab ntawm cov ntaub ntawv dhau sijhawm. Txawm li cas los xij, tswj kab kos suav nrog sab sauv thiab qis tswj txwv cov kab nrog ib tug centerline.

Hauv qhov no, daim ntawv qhia tswj hauv Six Sigma yog dab tsi?

Cov txheej txheem tseem ceeb ntawm Statistical Tswj (SPC) cuab yeej rau Six Sigma teg num yog cov tswj daim ntawv qhia - graphical taug qab ntawm cov txheej txheem tawm tswv yim lossis cov zis tawm dhau sijhawm. Hauv tswj daim ntawv qhia , cov kev ntsuas taug qab no yog pom pom piv rau kev txiav txim siab txwv suav los ntawm qhov tshwm sim ntawm qhov ua tau zoo ntawm cov txheej txheem.

Yuav ua li cas koj suav cov khiav ntawm ib daim ntawv qhia khiav?

A khiav yog ib tug series ntawm cov ntsiab lus nyob rau hauv ib kab ntawm ib sab ntawm qhov nruab nrab. Ib qho qauv uas tsis yog-random lossis teeb liab ntawm kev hloov pauv yog qhia los ntawm tsawg lossis ntau dhau khiav los yog hla ntawm kab nruab nrab. Los txiav txim tus naj npawb ntawm khiav saum toj thiab hauv qab qhov nruab nrab, suav tus naj npawb ntawm cov sij hawm cov ntaub ntawv kab hla qhov nruab nrab thiab ntxiv ib qho.
