Te Hoahoa me te Hangarau o ngā Pūnaha Whakahaere Kounga
I tēnei taiao ahumahi e piki haere ana te whakataetae, ehara te kounga i te mea he uara tāpiri noa iho; he whakaritenga matua mō te whakaae hua me te whakawhirinaki a te kiritaki. Mā te kounga pumau ka āwhina ngā kamupene ki te whakaiti i ngā utu rahunga (te mahi anō, te para, me te whakahoki), te whakapai ake i te whai huatanga o ngā tukanga, me te whakapakari i te ingoa o te waitohu. Nō reira, ko te hoahoa me te whakatinanatanga o tētahi pūnaha whakahaere kounga he tūāpapa nui mō ngā mahi hanga me ngā mahi ratonga. Kei roto i tēnei pūnaha ehara i te mea ko ngā mahi tirotiro anake engari ko ngā paerewa, ngā tikanga, ngā raraunga, ngā hangarau, me te ahurea mahi e whakarite ana kia tutuki i te hua whakamutunga ngā whakaritenga.
1. Ngā Ariā Taketake o te Mana Kounga
Ko te Mana Whakahaere Kounga (QC) he raupapa mahi hei aroturuki, hei ine, hei whakarite hoki kia tutuki ngā whakaritenga o te putanga tukanga. He maha ngā wā ka whakaritea te QC ki te whakapūmau kounga (QA). Ahakoa e aro nui ana te QC ki te manatoko hua me te tukanga mā te ine me te tirotiro, e aro nui ana te QA ki te aukati i ngā raruraru mā roto i ngā pūnaha whakahaere, ngā arotake, te whakangungu, me te whakapai tonu. I roto i te mahi, ka whakauruhia e te hoahoa pūnaha whakahaere kounga pai ngā mea e rua—te whakaiti i ngā hapa pea mai i te tīmatanga me te kite i ngā hapa i te wā e taea ai.
E toru ngā whāinga matua o tētahi pūnaha whakahaere kounga whai hua: (1) te whakarite kia tutukihia ngā paerewa me ngā ture, (2) te pupuri i te ōritetanga o te putanga i waenga i ngā puranga, i waenga rānei i ngā wā whakaputa, me te (3) te whakarato urupare raraunga hei whakapai ake i te tukanga.
2. Wāhanga Hoahoa Pūnaha Whakahaere Kounga
a. Whakatauhia ngā hiahia me te whānuitanga
Ko te taahiraa tuatahi ko te tautuhi i ngā whakaritenga a te kiritaki, ngā whakatakotoranga hangarau, ngā paerewa ahumahi (hei tauira, ISO), me ngā whakaritenga ture. Me mārama te whānuitanga: mēnā kei te whakawhanakehia te pūnaha mō tētahi raina whakaputa kotahi, mō tētahi tipu katoa, mō te mekameka tuku rānei (ngā kaiwhakarato ki ngā kaituku). Mā te whānuitanga ka āwhina ki te whakatau i ngā tikanga whakahaere, ngā taumata tuhinga, me ngā whakaritenga taputapu.
b. Ngā tukanga mahere me ngā pūwāhi matua
Ka tīmata tonu te hoahoa QC me te mahere tukanga. Ko ngā tikanga noa ko ngā tūtohi rere, te SIPOC (Kaituku-Whakauru-Tukanga-Putanga-Kaihoko), te mahere rerenga uara rānei. I roto i tēnei mahere, ka tautuhia e te tīma ngā pūwāhi whakahaere matua e tino pā ana ki te kounga. Ko ngā pūwāhi matua ko ngā tawhā mīhini, ngā āhuatanga rauemi, te pūkenga o te kaiwhakahaere, ngā āhuatanga taiao rānei (te pāmahana, te haumākū, te ma).
Mai i konei, ka taea e ngā whakahaere te whakatau ko tēhea wāhi me tirotiro: ngā rauemi e haere mai ana (ngā rauemi e haere mai ana), ngā rauemi kei te tukatukahia (i te wā whakaputa), me te tirotiro whakamutunga (te hua whakamutunga). Ko te mātāpono matua, kaua ngā tirotiro e "hopu" noa i ngā hapa i te mutunga, engari me aroturuki i te tukanga kia kore ai e whanake ngā hapa hei raruraru nui.
c. Te whakawhanake i ngā paerewa me ngā paearu whakaae
Me whakamaori ngā paerewa kounga ki ngā paearu ine: ngā ine, te taumaha, te kaha, te tae, te ma, te mahi, me ētahi atu tawhā e tika ana. Ka tautuhia ngā paearu whakaae mā roto i ngā manawanui, ngā rohe whakatakotoranga (USL/LSL), me ngā whakarōpūtanga hapa pēnei i te mea nui, te mea nui, me te mea iti.
I tēnei wā, ka whakatūria hoki e te kamupene he mahere tauira (tauira whakaae) mēnā kāore e taea te tirotiro 100%. Me whakarerekē te tikanga tauira, te rahi o te tauira, me te Taumata Kounga Whakaaetia (AQL) kia whakaata i te mōrearea o te hua, ngā utu tirotiro, me ngā hua o te korenga.
3. Te Hoahoa o ngā Tikanga Whakahaere me ngā Utauta
a. Te Whakahaere Tukanga Tatauranga (SPC)
He huarahi tatauranga te SPC hei aroturuki i te pumau o te tukanga mā te whakamahi i ngā tūtohi whakahaere pēnei i te X-bar/R, I-MR, tūtohi-p, tūtohi-c rānei. Mā te SPC ka taea te wehewehe i waenga i te rerekētanga noa (take noa) me te rerekētanga nā ngā raruraru motuhake (take motuhake). Mena ka hangaia he pūnaha QC me te whakaaro ki te SPC, ka taea e te tīma whakaputa te mahi whakatika tere ake—ahakoa i mua i te peka ke o te hua i ngā whakaritenga.
b. Tātari Pūnaha Ine (MSA)
Ka hua ake ngā whakatau hē i ngā inenga ngoikore. Nō reira, me whakauru e te pūnaha whakahaere kounga ngā MSA pēnei i te Gage R&R kia rite ai ngā hua mō ngā taputapu ine me ngā kaiwhakahaere. He mea nui rawa ngā MSA i roto i ngā ahumahi e hiahia ana ki ngā manawanui pakari. Ki te kore he MSA, ka puta he "raruraru" i te tukanga ina ko te pūnaha ine tonu te mea kāore i te pumau.
c. Ngā taputapu tātari take pūtake
Ina kitea ngā hapa, me whakarato e te pūnaha he tikanga tātari pūtake paerewa. Ko ngā taputapu noa ko: Ngā tūtohi Pareto hei whakatau i ngā momo hapa, ngā tūtohi wheua ika (Ishikawa) hei mahere i ngā take, me te tikanga 5 He aha hei hura i ngā take pūtake. Mā te hoahoa pai ka tautuhia te wā e whakahaerehia ai te tātari, ko wai te kawenga, me pēhea te whakamaoritanga o ngā hua hei mahi whakatikatika.
d. FMEA me te whakahaere mōrearea
Mā te Tātari Aratau me ngā Pānga Rahunga (FMEA) ka āwhina i te mahere i ngā rahunga pea mai i te wāhanga hoahoa hua, tukanga rānei. Mā te aromatawai i te kaha, te tūponotanga o te puta, me te kitea, ka taea e ngā kamupene te whakarite i ngā mahi ārai. Ko ngā pūnaha whakahaere kounga hou e whakarite ana i te whakahaere mōrearea, e arotahi ana ki ngā rauemi QC ki ngā wāhi mōrearea nui.
4. Te Whakaurunga o te Hangarau me ngā Pūnaha Mōhiohio
I roto i te hoahoa o nāianei, kāore e taea te wehe i te QC mai i ngā raraunga matihiko. Ka taea te whakauru i ngā pūnaha mōhiohio pēnei i te QMS (Pūnaha Whakahaere Kounga), te MES (Pūnaha Whakahaere Hanga), me te ERP ki te tuhi i ngā hua tirotiro, te tūnga kore e tutuki, te aroturuki i te rota/puranga, me ngā mahi whakatikatika me te ārai (CAPA). Ka tautokohia e tēnei whakaurunga te whai i te hua - te kaha ki te whai i te hua mai i ngā rauemi mata ki te kiritaki.
Hei tāpiri, mā te whakamahinga o ngā pūoko me ngā tātaritanga IoT ka taea te whakahaere kounga i runga i te āhua o te wā tūturu. Hei tauira, ka taea e ngā pūoko wiri te aroturuki i te hauora o te mīhini, ka taea e ngā kāmera tirohanga te whakarato tirotiro tirohanga aunoa, ka taea rānei e ngā pūnaha whakaoho te whakatūpato i ngā kaiwhakahaere ina tīmata ngā au o te tukanga ki te whakatata atu ki ngā rohe whakahaere. Ka taea e te aunoatanga o te tirotiro te whakapai ake i te tere me te ōritetanga, engari me taurite ki te whakamana pūnaha me te whakangungu kaiwhakamahi.
5. Te Hoahoa o ngā Tukanga Whakahaere me ngā Tuhinga
Me "ora" te pūnaha whakahaere kounga i roto i ngā tikanga mārama, ngāwari hoki ki te whakatinana. Ko ngā tuhinga matua ko:
1. Te Whakatakotoranga mō te tirotiro me te whakamātautau (tikanga, taputapu, auau, paearu).
2. Ngā tohutohu mahi mā ngā kaiwhakahaere me ngā kaitirotiro.
3. Puka tuhi (ā-ringa, ā-matihiko rānei) mō ngā hua ine me te pepa tirotiro.
4. Ngā tikanga whakahaere hua kāore i te tika (te wehewehe, te tapanga, ngā whakataunga tuku: te mahi anō, te para, te tukunga).
5. CAPA hei whakarite kia tuhia ngā mahi whakatikatika me ngā mahi ārai, kia manatokohia hoki tō rātou whai huatanga.
6. Ngā arotake ā-roto me ngā arotake ā-wā hei tikanga aromatawai pūnaha.
Ehara i te mea he nui rawa ngā tuhinga pai; ko te mātāpono he rawaka hei whakarite i te ōritetanga, te whai i ngā whakaritenga, me te tutuki i ngā paerewa.
6. Te Whakahaere, Ngā Tūranga, me Ngā Pūkenga
Kei roto hoki i te hoahoa pūnaha QC te hanganga whakahaere: ko wai te rangatira o te tukanga, ko wai e tirotiro ana, ko wai e whakaae ana ki ngā tukunga hua, me pēhea te whakapiki i ngā take. He mea nui te pūkenga rauemi tangata ki te angitu. Me uru ki te whakangungu te mārama ki ngā whakaritenga, te whakamahi i ngā taputapu ine, te whakamārama i ngā tūtohi whakahaere, me te ahurea "kore-hapa".
He mea nui anō hoki kia mau tonu te mana motuhake o te mahi QC kia kore ai ngā whakataunga kounga e ahu mai i ngā whāinga whakaputa anake. Heoi anō, kāore te angitu e whakawhirinaki ana ki te QC anake; me mahi tahi ngā mahi maha (te whakaputa, te hangarau, te hoko, te whare putunga) hei whakatika i ngā take matua.
7. Te Whakatinanatanga, te Whakamātautau, me te Whakapai Tonu
Kia oti te hoahoa, me whakahaere e te kamupene tētahi whakatinanatanga whakamātautau hei whakamātautau i te reremahi, te kawenga tirotiro, te tere urupare, me te kounga raraunga. Mai i tēnei whakamātautau, ka taea e te tīma te whakapai ake i ngā pūwāhi whakahaere, te whakarerekē i te mahere tauira, te whakapai ake rānei i te whakatakotoranga pūrongo. Ko ngā tohu mahi noa (KPI) ko te reiti hapa, te reiti para, te hua tuatahi, ngā amuamu a te kiritaki, te wā arahi CAPA, me te utu o te kounga ngoikore.
Ko te pūnaha whakahaere kounga pakari e whakamahi tonu ana i te huringa PDCA (Mahere-Mahi-Tiro-Whakahaere). Ko te tikanga o tēnei, ehara ia kitenga i te hua whakamutunga, engari he whakakorikori mō te whakapai ake i te tukanga. Mēnā he ahurea whakapai tonu, ka noho te pūnaha QC hei taputapu rautaki hei whakapiki i te whakataetae, ehara i te mea he mahi tirotiro noa iho.
Te Katinga
He haumitanga te hoahoa me te whakatinanatanga o tētahi pūnaha whakahaere kounga e pā tika ana ki te whai huatanga, te makona o te kiritaki, me te pumau o te pakihi. Ka tīmata tētahi pūnaha angitu mā te mārama ki ngā hiahia o te kiritaki, te mahere i ngā tukanga, te whakatū paerewa ine, te whiriwhiri i ngā tikanga whakahaere pēnei i te SPC me te MSA, me te whakauru pai i te hangarau me te tuhinga. Hei tāpiri, ko te angitu o te pūnaha ka whakatauhia e te pūkenga tangata, te whakahaere tika, me te whakapau kaha ki te whakapai tonu. Mēnā he hoahoa tika, ehara te whakahaere kounga i te "tātari hapa" noa iho, engari he mea matua hei akiaki i te hiranga o te mahi.
